Science, Engineering & Environment Building, Salford

Sotech Ltd

5500m2 of Optima TFC+ has been used in the completion of the brand new Science, Engineering and Environment building on Salford University’s Peel Park campus.As you can see from the photos, a striking colour palette has been used in the modified window interface details. Interpon’s D2525 Ostuni Y2211I, 3030 High Gloss & 7022 High Gloss in 3.0mm Aluminium 3103 Grade PPC were selected.The unique overhang window details were created using the 20mm overlapping joint that is standard in Optima TFC+. A bespoke sharp edge detail was added to window interface locations for dramatic effect, creating a stunning visual contrast between the bright red window pods against the white vertical cladding as per the architect’s original design intent.Sotech assembled a full-size sample rig in the factory for the client, architect, main contractor and installer to view a full scale mock-up of the final proposed solution. This ensured that any design details or install sequences were scrutinised and fully understood before the project began onsite. Sotech then created a full 3D model of the project alongside their long-term partners Metclad Contracts. This allowed both parties to identify and avoid potential issues at the design stage before panels were fabricated and delivered to site.The SEE Building is Salford University’s brand new £65 million hub for discovery and innovation. Consisting of four stories over 15,500 sq meters, the department will house the university’s departments of Built Environment, Computer Science and Networking, Mechanical Engineering and Human & Natural Science, in addition to the university’s Morson Maker Space – an additive manufacturing and digital fabrication facilityTESTIMONIALS:Jamie Brown of Sotech said: “This is yet another example how close collaboration from day one, involving the full supply chain, ensures projects can be delivered on time and on budget. The very clever and intricate window interface details showcases just how versatile rainscreen cladding can be, whilst staying within the boundaries of a fully CWCT tested and accredited system.”Naveen Sandhu at Akzo Nobel said: “Great to see this installation following an increasing trend of injecting vibrant tones into the elevation. One of a plethora of schemes in Salford and Manchester adopting our enhanced D2525 PPC technology across the envelope. Pleasure to work with the team at Sheppard Robson and delivering yet another outstanding higher education facility with Sotech.”

Automotive - Nissan

Hart Door Systems Ltd

An innovative door design was required for a new manufacturing process about to be introduced in the new Nissan battery plant manufacturing facility. Project/doors:100 Bespoke Conveyor screensThe challengeNissan required a unique door for a new production facility. The doors needed to give 60-minute fire resistance and be capable of completing up to 400,000 open/close cycles a year. Further, the doors needed to meet strict air leakage criteria and be able to withstand sudden air-pressure increases. The doors also had to interface with third-party equipment such as conveyor belt controls and fire alarms. Each required an LCD display control panel that provided a quick and easy diagnosis of what each door was doing at any point in time. The solution Using an already proven design solution which Hart developed for the baggage handling system in Heathrow’s Terminal 5, Hart adapted the product to suit this new requirement. As this was not a product already on offer, invention and rigorous testing were required.The successA decade has passed since the doors were installed and commissioned. The facility continues the manufacture of the battery cells and the doors remain a critical part of the success of the plant and have proved exceptional reliability and total cost of ownership

1820m2 School Roof Refurbishment - St Edmunds Catholic Academy - IKO ULTRA Prevent 25

1820m2 School Roof Refurbishment - St Edmunds Catholic Academy - IKO ULTRA Prevent 25

IKO PLC

IKO worked with Brindley Asphalt on this school. The school has 900 pupils, works include replacing the defective waterproof covering, incorporating new tapered insulation to current building regulations and creating falls to remove the drainage of the surface water. Also, replacement of windows and M&E plant to the kitchen area.This was a highly complicated insulation design due to the deflection and backfalls within the existing roof. The roof had several different interfaces such as adjoining roof level, rooflight and specialist M&E equipment.COMPLEXITY AND WORKMANSHIPThere were many changes in elevation and some very neat workmanship was observed, the largest Insulation board was over 350mm deep. In most areas, tapered insulation schemes were designed to alter points/elevations of drainage run-off due to existing issues of ground-level flooding experienced by the site.THE EXCEPTIONAL ACHIEVEMENTS ON COMPLETION OF THIS PROJECT WEREMajor proportion of the work was carried out during the 2020/21 winter months.Impacts of Covid 19Removal of all surface water from a complex roof.The school remained in full operation and the key access point was via the central/core courtyard which involved critical management throughout the contract to ensure both the health and physical safety of pupils could be maintainedCritical programme to our works as access route was to be lost due to new-build extension start date already having been agreed immediately abutting our roof areasAssociated demolition of plant room and isolation of services was also undertaken
The Gate, Furnival Square, Sheffield

The Gate, Furnival Square, Sheffield

Ash & Lacy

Topping out at 64m tall, Furnival Square hosts a brand new £35 million, 445 bedroom, purpose built student accommodation building on a prime site in the heart of Sheffield City Centre, adjacent to the Sheffield Hallam University campus.Built by McAleer & Rushe and aptly named the ‘The Gate’, the 22 storey building offers modern, quality student accommodation to support Sheffield’s thriving higher education sector. The building is designed to a BREEAM Very Good rating, developed and detailed by TODD Architects using the latest in Revit and BIM technologies.The specification called for the use of special bricks that gave depth and texture to the external skin. The 22 storey student accommodation tower also had to comply with all current Building Height Regulations for residential use and the construction team was faced with the considerable additional challenge of completing the build during global pandemic restrictions.Ash & Lacy provided over 4,000m2 of the fully-tested noncombustible, mechanically-fixed NaturAL-X brick cladding system, suitable for residential buildings above 18m tall. The system is also CWCT A1-rated and BBA certified (20/5773). Brick choice was SD102 from the Simplicity range.This lightweight system offers fast and simple installation and enabled a large amount of labor to be completed offsite, improving time efficiencies on site and facilitating just in time delivery.Over 50,000 cut and bonded corner bricks were manufactured at our in house facility, creating the deep castellating reveals that sweep across the building elevations. Soffit bricks were designed and manufactured to return underneath window heads, providing a realistic genuine brick aesthetic at key interfaces, achieving the original design intent.

G Park Northampton - Promat has played an instrumental part in the fire protection of the latest unit of GLP’s warehouse and logistics facility, G-Park, Northampton

Promat UK

Promat has played an instrumental part in the fire protection of the latest unit of GLP’s warehouse and logistics facility, G-Park, Northampton - providing a tailored 240-minutes fire resistance solution for Unit 4, a132,000 sq. ft speculative warehouse/distribution unit.  Situated within the popular Moulton Park industrial estate just north of the town and within 10 miles of J15 of the M1, G-Park has exceptional transport links, access to national markets, a locally skilled workforce and is home to a wide range of regional and national companies.   At short notice, the latest and final unit within the park required a solution that provided 4-hour fire resistance for the steel frame construction. Sub-contractor FAA Installation Ltd traditionally uses intumescent paints in its projects, but as this method was unable to meet the 4-hour fire protection required for the steelwork structure it was decided that boarding would be a more suitable alternative.  Promat VERMICULUX®-S and TD Boards® were specified for the project by Encon, a leading Promat distributor, as they knew that these were two of a limited number of products on the market that could meet the project’s requirements.   Promat worked closely with Encon and FAA on the final specification to provide a solution that could not only achieve the 240-minute requirement, but could also overcome the design complexities of the project, including fixing to both the structural steel and cladding rails, which most traditional boards were unable to accommodate. The completed installation demonstrates how VERMICULUX®-S and TD Boards® can interface together to create robust fire protection for warehouse and industrial applications. 
Premium Roofing Membrane for Luxury Holiday Accommodation

Premium Roofing Membrane for Luxury Holiday Accommodation

IKO PLC

The Clowance Estate is an all-year-round luxury holiday accommodation based in Cornwall. Recently, the estate decided to include a tree house in their holiday complex which is situated in a forest location and looks over a lake.Blue Forest -the world’s leading tree house consultancy – is involved in the design of this luxurious holiday home consisting of two main intersecting circular elements (one radius 2600mm and the other 3700mm) and one rectangular zone. The tree house has an outstanding design incorporating modern materials and a bold sharp angular canopy roof.The concept demanded a complex roof design as it had to meet so many requirements for visual appearance and detailing work such as conical-to-conical and conical-to-dual pitch valley interfaces and curved fascia detail.The steeply designed pitch made the installation very challenging. As the aesthetics were an important element of this high-calibre project, it was essential to achieve excellent workmanship standards on crisp lines of the field area, drip trim facets and standing seams.The roof build up consisted of three layers of 6mm plywood which were waterproofed by 110m2 of fully bonded IKO Armourplan P PVC Membrane. Standing seam profiles were also installed on a faceted deck using contact adhesive to give the roof the desired sharp look.IKO Armourplan P is a membrane unique to IKO Polymeric. With its superior reinforcement and the use of premium quality PVC throughout, the membrane’s enhanced formulation provides ease of installation.The extra flexibility of the membrane helped to achieve the desired tight and crisp details on the standing seams. It is also completely UV stable which makes the membrane more durable.
340a Clapham Road

340a Clapham Road

Ash & Lacy

In partnership with leading global investment firm KKR, Regal London recently completed a strategic new site at 340a Clapham Road, SW9, situated between Stockwell and Clapham North. Previously a brownfield site (tool hire depot), the site has been completely transformed into a vibrant mixed use, residential-led development, totalling 94,740 sq ft and will deliver 62 one, two and three-bedroom apartments spread over nine floors. The ground and lower ground floors also comprise approximately 18,250 ft2 of flexible commercial space. Planning permission was granted in June 2017 following a collaborative working relationship with the London Borough of Lambeth and the project reached its completion in 2021.With a high quality and contemporary design, both of which are hallmarks of Regal London schemes, the development perfectly complements the surrounding streetscape of new build and period properties, featuring a subtle interplay of façade materials including brick, aluminium and glass installed by Buildtherm Services. Ideally located for commuters, an established network of transport links is within easy reach of the development, with Stockwell Underground Station just 0.2miles away, as well as Clapham North Underground Station and Clapham High Street Overground Station both within a short walk. A thriving social and leisure scene is also nearby, led by the bars, pubs, restaurants and cafes, as well as a selection of amenities, in situ along the lively Clapham High Street and its surrounds.The undeniable kerb-appeal of this luxury residential development is testament to the design capabilities of the modern methods of construction used throughout the build and the quality of workmanship involved. The architect’s ambitious concept design called for a modern and sleek interpretation of the surrounding vernacular to satisfy planning requirements. The vision is clearly represented by the multiple challenging interfaces; including large expanses of glazing, cantilevered balconies and rooftop garden spaces which represented an important consideration within the design of the main structure and supporting steel frame systems. In order to comply with the latest building regulations for residential buildings over 18m in height, topping out at 9 storeys, Regal London also needed to ensure that all façade materials met with the requirement for non-combustibility, with a minimum EN13501-1 rating of A2, including the balconies.Over 3000m2 of A1 rated NaturAL-X brick cladding has been installed across several new elevations, with the architect having selected 3 different brick finishes to satisfy planning requirements, specifying subtle and muted tones including a textured dark, smooth off-white, and glazed white. As well as varying the colours and textures of the brick cladding, hundreds of bespoke cut and bonded return bricks were manufactured to suit the angular interfaces at balcony levels. The project design also called for elements of flexibly orientated brick coursing, with soldier courses, stack bonded and soffit return sections featuring at ground level and interspersed within the columns and beams stretching across the front elevation. The adaptability of this BBA certified innovative brick cladding system allows for modern interpretations of brickwork design to be easily integrated using standard components, without any requirement for additional structural support and with the added reassurance of all relevant system testing.Set back from the main brick façade, the top two floors featuring luxurious penthouse apartments are clad in VariAL-CF2 Concealed-fix 3mm aluminium cassettes, with a powder coated finish produced to Qualicoat standards. This CWCT tested, A2 rated rainscreen system is designed to accommodate large format vertically orientated modules, as well as complex details such as soffits, verges and goalpost details; making it eminently suitable for the balcony fascia areas too. Concealed fixings located in the panel joints are colour coated to match the panels, delivering an uninterrupted aesthetic. With long-term maintenance in mind, VariAL-CF2 allows for individual panels to be demounted, removed and replaced if required, without causing any detriment to the surrounding areas.
King's Cross Gasholders Triplets, London

King's Cross Gasholders Triplets, London

The Safety Letterbox Company

THE PROJECTWe start 2018 with a case study that is truly the epitome of ingenuity and design! What a privilege to be involved in Gas Holders.King’s Cross is inextricably linked to London’s industrial past. The telescopic gasholder was invented in 1824 and provided the storage needed to meet the demand of an ever-expanding city.The interlocking gasholder triplets were built and revised between 1860 and 1880 and now, some 150 years later, they are once again responding innovatively to The Capital’s ever increasing population. Architects Wilkinson Eyre have produced a truly stunning and extraordinary development.Luxury apartments designed by Jonathan Tuckey Design have designed internal beauty that benefit from a Regent’s canal waterside location, breath-taking communal roof gardens, and an array of amenities elegantly furnished and dressed by London interior designers No12 Studio. Amenities include spa and gym, residents lounge and a sophisticated entertainment suite including private dining and catering kitchen, a 14 person screening room, with an adjacent elegant games room, for use before or after the show.The Gasholders lobby displays extraordinary attention to detail in its integration of the building’s industrial heritage with contemporary design and style. A 24-hour concierge team operates from a bespoke desk made in natural stone, while polished concrete floors with brass inlay, a sweeping spiral staircase and feature light sculpture introduce guests to the drama of the interior. It also houses the bespoke brass mailboxes painstakingly developed and created by our Innovation team.THE PRODUCTBack in 2014, we were approached by Wilkinson Eyre Architects to create a curved bank of mailboxes with particular emphasis on the hinge and finish, the overall requirement for a suitably stunning yet functional solution.Houston Cox Central were awarded The Triplets contract to design, manufacture and install all specialist joinery, which included the solid brass bespoke mailboxes that formed an integral part of the reception area. The joinery design presented its challenges, working within a cylindrical building with zero design tolerance. All the joinery interfaced (between panels, doorsets, wardrobe and vanity units) with each other to form an integral part of each living space. As on previous projects, we worked closely with Houston Cox Central over many months to ensure the clients brief was met. The bespoke designed mailboxes aligned with full height panels following the curved atrium wall within the ground floor reception area. The unique design of the brass mailbox doors with robust solid continuous brass hinges are very fitting for this iconic building. Houston Cox Central are delighted with the end result, having completed the installation late 2017.

Carea Façade

Location: London, UKConstruction type: new buildInstallation system: wall cladding with backing structure (CWB)Product: SMOOTH MATTArchitect: The Kalyvides Partnership4 Merchant Square East in Paddington is a magnificent addition to the Merchant Square Development but crucial to the design of this distinctive and elegant £87 million residential building is a facade system which includes cladding from leading specialist Carea.Designed by The Kalyvides Partnership, the sixteen storey residential building forms part of the Paddington Basin waterside development and is now a focal point in the area due to its striking and aesthetically pleasing exterior façade, designed to create a visually stimulating building.To achieve the impressive façade, The Kalyvides Partnership specified a number of different materials, including glass, curtain walling and rainscreen cladding, a key ingredient being mineral cladding from Carea.To create the stunning façade specialist contractor Prater, working for main contractor Carillon, were called upon. The challenging project saw them complete the installation of the 9,700 m2 facade which required the management and installation of 20 different products and systems across multiple interfaces – Carea’s cladding with backing structure being two products (grooved panels and anchor panels). The Kalyvides Partnership specified 14mm low pressure Carea grooved cladding which along with the 16mm anchor cladding created a chequerboard pattern effect. Chosen in white with a smooth finish to create symmetry in the building’s decorative facade, the high quality of each Carea cladding panel creates a stylish finish which met the architect’s vision.‘The concept for the use of the Carea stone was to form an organising sheer wall component,’ commented Tryfon Kalyvides, Partner at The Kalyvides Partnership. ‘This commenced at ground and first levels, progressing as a winding aesthetic system encapsulating the façade elements, rising to the thirteenth floor and then descending vertically to the ground on the east.’Each of the Acantha and Artema panels were installed by Prater using innovative grooves at the top and bottom edges to create a seamless finish. As well as an efficient secret fix installation process, Carea cladding panels provide several performance benefits and were crucial to the building achieving a BREEAM ‘Excellent’ rating. Offering a high degree of insulation, they will play a pivotal role in the development’s thermal efficiency, thereby lowering its heating needs and aiding sustainability.With this striking new development along the Grand Union Canal now complete, Carea has been instrumental in creating a building which will continue to perform and look great for generations.

This is also where its name comes from.14,000 m² of parklandAll objects are being built with net zero-energy efficient features. Solar collectors are being installed on many roofs to provide hot water. As part of the thermal insulation, Schöck’s Isokorb® T thermally separates elements while forming part of the structure. It is being used here on a massive scale in different variants. Around 1,700 units were installed in five different building complexes. The versatile range of Schöck Isokorb® T structural thermal breaks allowed the planners great scope for design and energy efficient solutions, since they not only offer thermal separation and additional fire protection but also freedom of interface access (e.g. balcony to living space). In addition to Isokorb® T, Schöck Dorn (shear reinforcement, heavy-duty dowel), Schöck Bole® (punching shear reinforcement) and the Sound Protection System Schöck Tronsole® (for stairwells) were used in many installations.A total of 89 apartments with 75 balconies will be built whereby the ground floor apartments each have their own small garden. The roof surfaces are all planted. The living areas of balconies that extend outwards have an L-profile. The resulting visual plant staircase on the sunny facades creates the impression of a hanging garden for the residents and neighbors. This has a relatively striking effect and yet this version of gradation and the enclosed balustrades provides a certain degree of privacy for the inhabitants. To achieve the desired level of green, balconies are to have two flower boxes each (1.5m in length) that will be tended to by the residents. The three-meter deep balconies are thermally separated with Schöck Isokorb® T elements.Arcades thermally separated"We have done everything that is technically expedient to save energy. The Isokorb® T has been installed in the terraces and arcades" (Karrer). A solar system was installed on the roof. "All the green diminishes the specified high construction density," says the architect. Gradated terraces ensure that even in the courtyards there’s good light. The buildings were handed over in the summer of 2014.
Fire training centre home & dry with Condair

Fire training centre home & dry with Condair

Condair Limited

Firefighters at the new training centre of the Cheshire Fire and Rescue Services at Winsford are benefiting from a Condair dehumidifier to dry out their protective kit at the end of each wet training exercise. The equipment was specified by T Clarke, one of the UK’s leading building service companies, for the centre’s drying room as part of the new build project.Equipment ensuring the strict control of moisture in a drying room is essential to save firefighters’ gear from the effects of water damage after a call-out or a training exercise. It’s vital that they have access to a drying facility to prevent extensive damage and potentially significant replacement costs for the fire service. Condair supplied T Clarke with a Condair DC 50W wall-mounted unit that had to be in place at the Centre within one day of arriving on site prior to handover to fire chiefs. This timescale proved no problem as the dehumidifier was tailor-made for the job and was easily installed by the contractor’s engineers.T Clarke’s Project Engineer, Doug Lumb, explained: “A new build project like this is really quite exciting with the scope to start from scratch. The Condair DC 50W dehumidifier was actually chosen by our designers, as it fit the bill perfectly for the environment. The unit size was based on the quantities of kit hung in the room to dry when the firefighters return to the Centre at the end of their training exercises. It’s a reliable product and currently operating at the station just as expected, plus installation was really simple and didn’t take long at all, so all very good. I would definitely specify Condair dehumidifiers for future projects.”The Condair DC 50W is part of a range of condensing dehumidifiers that offer powerful drying performance. It is easy to install and has an attractive galvanised sheet metal cover with powder enamel finish. The wall-mounted versions can be supplied with steel feet for extra stability. As well as the built-in digital user interface, the dehumidifier has an optional remote wall controller, which can be located up to 50m away. Remote mechanical hygrostats are also available.The unit installed by T Clarke has a dehumidifying capacity of up to 49 litres per day (@30°C/80% RH). Capacities in Condair’s wider condensing dehumidifier range from 49 to 930 litres per day with airflows of up to 8,000m³/h. They can provide dry air directly to a room or be connected to a building’s ducted ventilation system. Models are also available with an external condenser that can expel the heat generated during the drying process remotely and therefore manage temperature control as well as humidity.Winsford’s fire training centre offers the most up-to-date technology to ensure the best possible training for existing firefighters and new recruits, serving a large area of the North West Fire Services. After training the firefighters return to their allocated bases from where they operate a shift system of nine firefighters and officers crewing a fire engine, major rescue unit and incident response unit 24/7. The training centre operates Monday to Friday with high numbers of staff and trainees, and potentially a lot of clothing that needs drying out on a daily basis, so reliability is essential.
Prestigious building complex in London benefits from the next generation of the automatic parking system

Prestigious building complex in London benefits from the next generation of the automatic parking system

Lödige Industries

The first to enjoy the latest generation of Lödige Industries' proven technology are the homeowners of a luxury residential complex containing 29 luxury apartments for the over 60s on Fitzjohn’s Avenue in London. The building’s footprint could not accommodate enough conventional parking spaces and street parking was not a viable option. To meet this challenge, Lödige Industries, on behalf of the London-based residential development company Lifestory Group, installed a fully automated parking system with capacity for 29 vehicles, all equipped with electric vehicle charging docks, at a depth of 10m over two levels.Today's cars are bigger, heavier, and more and more often electric. We are responding to this development with a major update of its RESPACE technology. Among other things, we have increased the load capacity of the automatic parking solution to 3 tons, adapting the equipment and drives as well as expanding charging technology for electric vehicles. Globally the number of electric vehicles is on the rise. In 2019 alone, global e-vehicle stock climbed by 43%. Architects and developers alike are forced by regulations as well as buyer intent to offer e-charging in their parking facilities. This has long been an issue for many automated parking technologies, especially since car manufacturers have yet to agree on a standard for wireless charging.  The new RESPACE offers 100% e-charging for all spaces. Following an engineering breakthrough, the new technology is resilient against dust and dirt and responds automatically to periods of high system activity to ensure vehicles can be retrieved quickly and efficiently at any time. The new e-charging technology supports individual billing per vehicle and can be retrofitted in existing systems. Furthermore, an intelligent load management system automatically exchanges a fully loaded car with an empty car, if not all parking spaces are equipped with a charging facility. RESPACE uses a sliding pallet system and provides optimal use of space in residential developments as it eliminates the need for drive or walkways within the parking system and the requirement for internal or external access ramps, the combination of which can save more than 60% of the space taken up by traditional car parks.  Faster installation and commissioning times are another major benefit of the optimised RESPACE technology. This increases the number of parallel movements possible, whilst avoiding any single point of failure. New engineering software integration also means that system configurations can be tested early in the development process using simulation programmes to optimise planning and give a greater range of viability options to developers.An improved cabin setting means that drivers accessing the system are now going to benefit from a much-improved user guidance. Users of the system will enjoy the new on-screen visualisation with specific step-by-step task focused instructions, on larger, eye friendly screens. In-cabin panels have been given a modern design overhaul in line with Lödige Industries’ successful CUBILE technology and are now equipped with security and motion sensors, cameras and number plate recognition technology if requested.  In addition, a new app, called ParkGO!, now available in iOS and android app stores, enables users to park and recall their vehicles with the touch of a smartphone. A handy system status view allows retrieval of cars during less busy periods. With its overhaul of the cabin and introduction of the app, Lödige Industries has brought the luxury parking experience that has defined their public automated parking systems in outstanding architectural objects in Denmark and elsewhere to private parkingUSP -       The Car Park System RESPACE is an extremely space-saving option - up to 60 percent more cars can be placed in the same space in comparison to traditional car parks. -       Residents will use a modern and intuitive smartphone app ParkGO! developed by Lödige Industries to retrieve their cars.  -        Due to the increase of e-vehicles, the new RESPACE offers 100% e-charging for all spaces. Easy parking and unparking guaranteed by parking aids, safety checks and the provision of the vehicle in the direction of travel. “This solution ticked all our boxes. With Lödige’s RESPACE, every apartment has its own parking space and owners will benefit from a seamless parking experience; they will simply drive their car onto a pallet in a cabin, the only interface between the driver and the car park. From then on, the process is entirely automated.”David Newey, Director of Development at Lifestory Group
Harrods Grand Entrance, Hans Crescent, London

Harrods Grand Entrance, Hans Crescent, London

Domus Facades Ltd

Two years after Domus Facades completed their stone contract works for Harrods Entrance Hall 3 on Basil Street they received a call back to tender for Harrods next large project, their 1930’s Grand Entrance Number 5 on Hans Crescent.  The project was shortlisted for the World Interior of the Year awards and won the Blueprint Awards for Best Interior Project (Leisure).This would be a step up from the previous project with a more generous budget for more opulent marble. When you enter from Hans Crescent you realise you have entered something special.  A clever combination of hand-crafted materials complimented by French and Italian marble, conceived by MAKE Architects.When you enter you immoderately walk onto 650m2 of Grigio Genova marble paving. Flanked either side of you is 945m2 of Grigio Genova shear walls, uninterrupted running 25 metres from the lower ground floor level to the sixth-floor level.As you leave the entrance hall you pass through Noir St Laurent marble portals on every level (240m2).Many hours and flights were dedicated to the selection of stone material. To achieve the finish a dry laying process was agreed to understand the characteristics of Grigio Genova and Noir St Laurent to draw out the best of the material.  Every portal (21) on the project had a dry lay. This enabled the design team to control the direction of the veining, create subtle book matching and dictate the final impression.Due to the program and volume of Grigio Genova (1,595m2) a control range was set up to provide more practical control measures. The material proved to be quite wild as you moved through the quarry and ran from bold dark tones and features to a light subtle tonality. The lighter subtle tonality and detail is what you will see on the project. The result of this selection meant a longer procurement time frame had to be worked with.The scant selection was the first point of the quality control process. When the panels were cut to size another check was carried out against the control range. A third check was carried out on site to deal with any failures in visual checks when the panels are wet from the factory. The final selection was carried out on site on the scaffold boards! The Grigio Genova marble panels were laid out vertically in line with the shear wall and the Architect selected which panel would go were.On the ground floor lies the White Hall Corridor. This is formed of large format panels which infill between 13 curved archways and pilasters all formed out of Grigio Genova marble.  Heavy lifting equipment was used to place the panels on Domus Facades support system. Domus Facades used Stone Circle in Basingstoke to carry out the CNC work to the archways and the concierge desk.  You will notice the White Hall skewers as you walk down its path. Setting out the project was one of the great challenges due to the numerous levels on every floor.On each level the stone work interfaces with high-definition advertising screens, information boards and services often creating very tight fixing points. There are over a dozen secret access hatches across the hall built into the stone panels to enable regular maintenance.What is behind this marble stone work is where Domus Facades expertise also come into play. Behind the stone work is a complex cavity of services to enable the hall to function. Domus Facades had to allow for an uninterrupted support system spanning up to 4 metres floor to floor. This allowed for services to work behind the stone comfortably. The bronze channels that interrupt the stone shear walls also act as air ventilation by using dummy panels.Strip out and refit projects on grade II listed building as old as Harrods tend to through a number of surprises at you.  Domus Facades design and installation team had to set themselves up on site to be able to react immediately to situations that changed. Because of the tight program they had to strip out existing works, carry out a survey and design the substrate and support system in situ.  Awards worth mentioningWorld Interior of the Year 2017 Shortlisted - RetailFX Awards 2017 Shortlisted - Best Public Space SchemeBlueprint Awards 2017 Winner - Best Interior Project (Leisure)
Welsh Slate helps save Dover mansion block from its Waterloo

Welsh Slate helps save Dover mansion block from its Waterloo

Welsh Slate

Dover’s Waterloo Mansions are treated to a Welsh Slate reroof. An unusual double-mansard roof on a Grade II listed seafront mansion block is enjoying a new lease of life, thanks to Welsh Slate. Some 11,000 Penrhyn Heather Blue Capital-grade slates from Welsh Slate now adorn the roof and elevations of Waterloo Mansions, part of a Georgian terrace which overlooks Dover harbour, designed in the 1830s by Philip Hardwick, architect of the Euston Arch. The multi-million pound project to refurbish the six-storey building envelope for client Dover Harbour Board was completed this summer by main contractor Walker Construction after several years, and several Covid lockdowns. Architects Hazle McCormack Young LLP were commissioned to carry out a series of specific refurbishments/repairs to areas of the building. But the project eventually grew to encompass a full exterior envelope refurbishment to address the poor condition of the fabric and rectify some of the original design defects and subsequent poorly executed repairs/alterations that were contributing to the deterioration of the building. Challenges included its Grade II listing which required extensive discussions and close collaboration with Dover District Council’s heritage team, its highly exposed location on the historic seafront, and resolving issues with the original design without impacting the character of the building in a Conservation Area. Original slates taken from the roof and elevations of the fifth and sixth storeys of the older parts of the building were identified as Welsh and the specified 500mm x 300mm products from Welsh Slate were the closest match. Project architect Nathaniel Seall said: “Some areas had been previously replaced with slates we believe were Spanish and the appearance did not match. The use of traditional materials and techniques as close as reasonably possible to the original was a key part of the project philosophy and approach taken by the client and design team.” The upper and lower mansards are steep (up to around 72º), which affected the overlaps and some of the leadwork detailing, but the specification was otherwise mainly determined by the size and format of the original slates to maintain the appearance, as well as the exposed location, to ensure the roofing and cladding covering would be robust enough to withstand the coastal conditions. The roof presented a wide range of features – hipped ends, several changes of pitch, parapet gutters and dormer windows. It also had to be vented below the coverings, as a layer of insulation was introduced between the timbers to improve its thermal performance. This meant careful detailing at all the direction changes – eaves and ridges, for example - to ensure the ventilated cavity was maintained but still achieving the weathering. The slate’s main interface is with traditionally executed leadwork to abutments, parapet gutters and the roof crowns, which required careful detailing and close collaboration with the specialist roofing contractor, Butler Brothers Roofing, to maintain the ventilated cavity below the coverings. Here, the architects made extensive use of stainless steel formers to the leadwork in place of timber grounds, as this keeps these details very slim and discreet, allowing them to be incorporated without impacting the balance of lead to slate and affecting the overall appearance. Nathaniel said: “The Welsh Slate plays a significant part in the project as the roof covering was the only element of the fabric to be fully replaced. Everything else has been refurbished or repaired in situ. It is also an important part of the overall appearance and character of the building, particularly with the slightly unusual double-storey mansard.” He added that buying British had a role to play too. “While the heritage connection and desire to match the original covering from a conservation point of view was the principal driver behind selecting Welsh Slate, we were also conscious of the general consensus that the longevity and robustness of a Welsh slate is superior to other options, and given the condition and scale of the project felt that this made it more appropriate,” he said. So too did slate’s sustainability. Nathaniel said: “As a conservation project where the material choice is somewhat pre-determined, this was not initially as much of a consideration as it would be on other projects, but we do take the overall environmental impact and carbon cost of the materials we specify very seriously, and in this respect a natural, more locally-sourced, durable, and in principle re-usable material like slate has many plus-points. “Part of the interest in this project, and in conservation work generally, is understanding how some of the materials and techniques used in the past can be adapted to modern construction, and actually have better environmental credentials than many of the more modern, commonly-used materials we are familiar with. “As a practice we have specified Welsh Slate in the past, principally on other projects with a conservation aspect. Often this ends up being changed as part of value engineering, unfortunately.” Butler Brothers Roofing were 18 months on site fixing the Welsh slates on 633m2 of roof with two stainless steel nails each, to minimum headlaps of 76mm (on the vertical faces of mansard) and 98mm (to roof pitches over 30°) over counter-battened sarking boards. Director Gary Butler said: “This project was very challenging if you take into consideration the problems with updating the insulation and ventilation whilst trying to adhere to conservation rules. The specification shows the complexity of the project. But the Welsh slates performed brilliantly, as they do every time.”

Welsh Slate

Two types of Welsh Slate feature on the new roof of London’s Irish Embassy. The £2.5 million re-roof of the Grade II listed Irish Embassy in London, with more than 10,000 Penrhyn Heather Blue slates from Welsh Slate, has required its own exceptional levels of diplomacy. DarntonB3 Architecture had multiple challenges to factor in when it came to specifying the replacement slates, including the City of Westminster’s planning department, which was keen to see as many of the existing slates re-used as possible and required convincing to embrace the “new” metric sizes. Then there were landlords Grosvenor Estates, leaseholders the Department of Foreign Affairs and Trade, and Historic England, not to mention the site being opposite Buckingham Palace, on a “Red route” with diplomatic bays nearby, and between two of the most important Conservation Areas of Belgravia. Work began on the landlocked Grosvenor Place site in March 2018, a year after DarntonB3, who are specialist conservation architects, were appointed to oversee the project, and has just completed (January 2019). Two types of Welsh slates have been used on the former terraced town mansion with decorative metal roof crest that was designed by architect Thomas Cundy, who was surveyor to the Grosvenor Estate at the time, and built in 1868 in a French Renaissance style. Roofing contractor Mundy Roofing was involved at an early stage in the project and were ultimately appointed as principal contractor. Specialising in leadwork and natural slate roofing, they were pivotal to the project’s success. A total of 600m2 of County-grade 500mm x 300mm slates have been used on the numerous standard 30° to 35° pitched roofs while Capital-grade bespoke arrow-head slates of the same colour but sized at 400mm x 250mm were used around dormer windows on the 80° mansard roof elements that are reminiscent of Paris and feature lead secret gutter detailing around the perimeter. There is also some vertical slating to the rear elevation.  The old 5mm to 7mm thick slates had been on the roof since it was first built 150 years ago. The rectangular ones had been slightly longer and narrower, at 510mm x 255mm, while the arrow-head slates had been smaller all round, at 350mm x 200mm.  But a roof survey showed they were not laid to the correct bond or headlaps and fixing points were far from ideal and non-existent in places (the headlaps between 0 and 50mm), leading to the hardened sarking underneath becoming sodden in places. In fact, most of the roof had been repaired over the years with different types of slates using temporary lead tags or painted with a bitumen solution in an attempt to prolong its life. DarntonB3 argued that if the roof was re-installed as existing, its appearance would alter as they would have no option but to lay the slates at the correct headlap which would create additional courses. In addition, using the slightly larger arrow-head slates for the mansard roof would enable them to form a more robust detail at the abutments to the dormers and party wall.  Home to the Irish Embassy for the past 70 years, the building comprises office and entertainment space. The traditional timber truss roof featured timber sarking boards with penny gaps, a form of construction usually found in Scotland. The slates were then fixed with copper nails directly to the boarding without any timber battens. Once city planners had agreed to 100% replacement of the Welsh slates, at the new metric sizes (a process that took a year), the addition of timber counter battens, to improve ventilation of the roof and prolong the life of the new slates, was also proposed by the Architects. Mundy Roofing produced sample comparison mock-ups to demonstrate to the conservation officer this change would not be detrimental to the building’s character. As it is, the interface details where slates have been lifted has not altered the character of the building and the introduction of battens would not be known by the general observer.  DarntonB3 senior associate Matthew Jones, who was project manager and lead architect throughout, said: “Westminster City Council are regarded as one of the leading conservation-led councils in the UK, with some of the highest standards and criteria to meet, and dialogue with the conservation officer was detailed and robust. The need for wholesale replacement of the existing slate due to them being at the end of their life was a delicate decision and sufficient evidence of this necessity was proven. The replacement of the slates with metric sizes was also an extensively discussed item but the principal contractor and Welsh Slate worked with us to develop the narrative.” Keith Hamilton, an architect accredited in building conservation, acting for DarntonB3 alongside Matthew was reasonably sure Welsh slates had been used previously but was keen to ensure the correct thickness and grading were eventually used throughout the renewal process.  He said “We have specified Welsh Slate on numerous other projects and their reputation for the highest quality precedes them. We were able to argue the merits of increased ventilation behind the slates using cross battening in lieu of direct nailing to the existing sarking board, which in the majority of areas had survived over 150 years’ performance. “The risk of lack of ventilation on the lower roof pitches behind the slates was particularly relevant at the eaves and head. We had previously considered introducing slate vents and felt underlay to augment any need for ventilation but the existence of the ‘penny gaps’ in the sarking boards encouraged us, to believe that this was not required.  “This was another point of continued discussion with the conservation officer who was against an underlay in this instance. The timber sarking was found to be in remarkable condition considering the lack of existing underlay and the direct fix of the slates, highlighting the quality of the original slates. Hence, there is no secondary layer apart from the slating itself and we trust the quality of the new Welsh slate will replicate the existing quality and last another 100 years.” Due to tight access on the roof, they were also able to widen the lead gutters and set back the lower courses of slates to avoid getting them broken. All the new Penrhyn slates were holed and traditionally fixed with 38mm copper nails as opposed to clipped or other methods. The standard-size slates were able to cope with the wide variation of roof pitches and new rooflights encountered by varying the lap and gauge slightly. In virtually every case, the slate junctions are with lead or copper flashings and as it was appreciated there is some risk of staining, all lead was treated with patination oil. Using new treated timber battens for fixing the new slates proved a great success as direct fixing into the old hardened sarking boarding would have been a major problem and time consuming.  Matthew said the support they had received from Welsh Slate had been “fantastic” and included a site visit to match the type of slate, a letter explaining the need to change from imperial to metric sizing, technical drawings of the arrow-head slates, technical information on the end life of slates and their unsuitability for re-use, on-time deliveries with little if no wastage, and recommending experienced slating contractors. Mundy Roofing were on site for a total of 10 months. Work included the rebuilding of three chimney stacks, involving 30 tonnes of stone and brickwork, and restoration of traditionally-forged wrought ironwork to the pavilion roof crest, all underneath a temporary roof. Russell Mundy said: “This project was extremely challenging due to it being a working embassy but Welsh Slate were excellent with their support in achieving planning consent and the product has received widespread praise from the client.” Matthew said: “Due to the extremely difficult access to this roof, we were conscious to use a slate that will require little maintenance (if any) and satisfy appearance for an extended period of time. Welsh Slate were able to provide technical studies comparing different types of slate and their longevity. This enabled the landlord, Grosvenor Estates, that the new roof should outlast the previous roof and match it entirely with other buildings nearby. Welsh Slate’s evidence on the existing slates being at the end of their useful life, and the lifecycle information of the new slates, helped give the conservation officer comfort that the right approach was being taken for the building.” Keith added: “Essentially, Welsh Slate ensured we got the right slate, quality, consistency and sizes for the varying roof pitches and conditions. There have been no problems with mixing batches or colour variations which can occur. They also met the stringent programme requirements, reducing risks of delay from the main contractor. To our knowledge, there have been no rejects on quality of slates. “The final result is the new slating looks exactly like it was envisaged in 1868, except with the knowledge it is better-fixed and easier to reach for maintenance, with a discreet fall arrest system fitted. The client is extremely happy with the quality of the final works.” Andrea Fox, senior architect with the property management unit of the Department of Foreign Affairs and Trade, said: “The team have provided us with an exceptional and beautiful project that we know will stand the test of time and one we are extremely proud to have commissioned.” “I want to thank the Welsh Slate team for the support they provided during our project and especially in relation to protracted issues relating to the listed building consent approval.”
