ArchitectPerkins+WillContractorMcLarenSectorCommercialLocationLondon, EC1150 Holborn is a new office building in central London, housing 1,000 employees from the brands that make up the DAR Group international consultancy.The eight-storey building is designed to maintain views of St Paul’s Cathedral. According to architect and occupier Perkins&WillThe interior design ensures each respective business keeps its unique identity while supporting cross-brand interaction.The blind design was focused on keeping the building ‘smart enabled’ using a KNX control system, putting a backbone in place to ensure all motorised shades were intelligently controlled over a KNX-BACnet solution. Meanwhile, the rest of the building had KNX integration capabilities through the internal risers, enabling future blind system upgrades to be made simply.Its state-of-the-art construction aims at LEED Platinum, BREEAM Outstanding and SKA Gold.The Requirements150 Holborn has been designed to be energy efficient, resilient, and adaptable to climate change. A high-performing envelope maximises both daylight and outside views during London’s long winters, while minimising solar gain. The building’s façade fins have been arranged to provide solidity and reduce solar exposure, and internal blinds augment this performance.As the spec developed, two themes emerged as fundamental to the architect’s approach. The building was to be smart and sustainable. In other words, it was to reflect the values of its users. Initially, we were asked to supply over 550 blinds.The ChallengesA smart building meant smart blinds. Perkins&Will proposed that the blinds respond automatically to a range of scenarios. As an example, when people book a conference room, they should walk in and find the blinds correctly set to their needs and in response to external conditions.However, after a value engineering process, it was deemed motorisation was only required for key areas. Out of 550 blinds, around 76 were motorised. The rest were specified as high-performance manually operated blinds using the same fabric. Furthermore, as mentioned above, the remainder of the building was complete with the ‘smart enabled’ KNX backbone, giving DAR Group the opportunity to upgrade the shading system in the future through KNX integration.Installation was another challenge. In the original drawings, the blind box seemed to float as there was no fixing detail. A fireproof treatment meant the blind box would need to sit outside of the intumescent expansion zone. The upshot was that we could not top fix the blind boxes to the façade and had to find a bespoke solution.Our SolutionOur team steered the client through a variety of smart blind options to work out the most cost-effective solution.Eventually, the client agreed with our recommendation of our S3 Synchronised Solar Shading automated blinds, using Vestamatic SMI motors and Warema KNX SMI actuator control systems, working with a Loytech KNX-BACnet interface. This provided intelligent BMS integration into our KNX system. Using this BACnet interface, the blinds were then connected up to the Schneider system, which was also using a KNX based controls strategy. Therefore, we were able to seamlessly integrate into their system and provide a simple solution for automated control to the end client.This not only met the requirements for smart blinds, but also provided a cost-effective way to cable and required a lower power supply than other systems, resulting in an M&E saving on the project. The blinds give DAR Group the functionality of time clock operation, alignment across multiple stop positions for a neat appearance, and intelligent links to the BMS.Perkins&Will specified maximum sustainability in every element of the project. In respect of the blinds, they wanted a high recycled content in the fabric.While several options were available, they all had limitations, particularly related to width. Some of the blinds were nearly three metres wide. The most sustainable fabrics could not span that space in one piece. Two lengths would have to be joined.Therefore, we recommended Verosol Enviroscreen 2%, which is a recyclable, fire resistant polyester fabric which would not need joins. The fabric has a highly reflective metallised backing to reduce heat and glare and is available in two widths to keep fabric wastage to a minimum.As well as guiding the architect through the intelligent and sustainable options, we also proved we are experts in solving installation problems.Our project manager and installation team designed a bespoke strap bracket which fixed onto the I-beam. From the bracket, a steel strap projected the blind pocket back into the façade. We were not allowed to drill into the I-beam so the team created a wraparound solution which clamped round the beam with its own fire-proofing.The gauge of the steel was carefully calculated as it had to be sturdy enough to withstand the weight of the blind system and box. Once installed, we applied intumescent paint to all the bracketry on the right-hand side of the blind box.The OutcomeThe Enviroscreen fabric created a highly efficient, attractive, heat and glare resistant appearance, giving uniformity to the exterior of the building, whether the blinds were automated or manual.The strap brackets did not just function well, they looked unobtrusive once the rest of the interior was decorated. While we had used similar strap brackets to install curtain tracks, this was the first time the solution had been designed and used with blinds. It is part of our DNA to design a bespoke solution to overcome any client’s fitting challenges.Another key to the project success was the way in which we surrounded the project with all stakeholders. Our team communicated with the architect, cost consultants and contractor simultaneously.Although the solution appeared to be architect led, the project was in fact design and build. Therefore, McLaren had full reign over the suppliers they chose as the main contractor, and we worked closely with them and Schneider to meet the brief set by Perkins&Will. Our team developed a very strong relationship with all parties during the project, maintaining constant communication by answering queries, overcoming challenges and providing confidence throughout.

ClientRHS WisleyArchitectWilkinsonEyreContractorOsborneSectorCommercialLocationWokingService DeliveredWe installed 200 blinds for the RHS Hilltop building, using a combination of manual and motorised rollers in both standard and blackout fabrics, alongside shaped and rooflight blinds.Situated at the Royal Horticultural Society’s flagship garden, RHS Wisley, the RHS Hilltop building became the first dedicated centre of excellence for horticultural science following it’s opening in June 2021.Designed to inspire the next generation of scientists and gardeners, the beautiful space is home to three separate gardens promoting wellbeing, world food and wildlife respectively, as well as an event space, café and sky terrace.With an emphasis on sustainability, RHS Hilltop is partly fuelled by renewable energy sources, including rainwater to reduce the reliance on tap water, and an incredible 99% of the waste generated during construction of the building was recycled.The RequirementsOn the initial specification, one room in particular stood out; the event space.Motorised blinds were required throughout to provide solar shading for the stunning shaped window, rooflights and large-drop windows, while standard roller blinds were required for the rest of the building.Furthermore, a combination of blackout and screen fabrics were required in the event room to create a versatile space.Our SolutionOur team worked closely with Osborne and WilkinsonEyre to ensure we met the design intent within budget.The initial proposal for the sloped glazing was for staggered drop-down roller blinds. However, as there was no fixing detail due to the limited amount of space within the roof line and bulkhead, this wasn’t possible.Our team overcame this by using a combination of upward pulling tensioned blinds, our ShadeTech® MSW system, and standard gravity drop roller blinds to ensure 8.3m x 5.4m section of glazing was fully shaded.The motors were fixed to the steel running across the middle of the window, with tensioned springs in the cassette and cables connected to a pulley above the window keeping the upward pulling fabric taut.Our ShadeTech® RBL-E motorised blinds were the ideal solution for the 6m-drop clerestory windows, as it allowed us to link the motors to save on wiring and hardware costs and create the aforementioned dual system, comprising of blackout and screen fabrics.Finally, blackout blinds were also required for the rooflights in the event space and circulation areas. Here, we used Shy’s ZIP Blackout system as the edge of the fabric is concealed with the side channels, preventing any light ingress.The OutcomeAs the photos demonstrate, the finish is spectacular.The dual system creates a versatile event space where heat gain and glare is controlled by the screen fabric, which also provides a view to the surrounding gardens, while the blackout fabric is also an option for scenarios in which this is required.The £35million project, led by WilkinsonEyre, was awarded the RIBA South East Regional Award in 2023.

ClientVR CaptialArchitectn/a - Design and Build with ContractorContractorODB GroupLocationKensingtonService Delivered13 SMI blinds powered by S3 Automated Blind SystemWaverley was appointed to deliver a high-spec blind control solution for a premium office fit-out at The Kensington Building in London.Working with ODB Group and their client, VR Capital, the project demanded an elegant, integrated system that complemented the sleek interior design and exposed ceiling aesthetic. Our S3 system, combined with custom KNX integration, provided the ideal solution, blending performance with discretion and simplicity.The RequirementsAs part of a high-end office fit-out for ODB Group, on behalf of VR Capital, the brief was clear: deliver a premium finish with seamless integration between lighting and blind controls. The client had selected bespoke switches to match their lighting controls, which were not part of the standard KNX range. With exposed ceilings and a clean aesthetic being central to the design, Waverley’s S3 system was the ideal choice to reduce visible cabling and floorplate equipment.The ChallengesThis project marked Waverley’s first time building and commissioning a full control panel entirely in-house, following our recent KNX integration training. The unique switches required a custom approach — we needed to integrate binary input KNX devices to convert the client’s switching signals into KNX-compatible commands. Added to this, there was no high-level containment for wiring and the ceilings remained exposed, requiring careful coordination with the site team.Our SolutionWe pre-programmed each motor with individual IDs and fully built and commissioned the panel off-site. This preparation allowed for a swift and simple installation once on site. Close collaboration with the electrical contractor ensured the panel was safely powered, and we worked with the project manager to agree on cabling routes in areas without traditional containment. Despite an initial mix-up regarding first-fix dates, open communication meant we resolved everything on the day.The OutcomeThe install and commissioning of the S3 system were completed efficiently and without issue — a smooth and successful execution thanks to thorough off-site preparation. While the final installation felt almost anticlimactic due to how quickly it was completed, it reflected the strength of our in-house capabilities and the benefit of continued technical training. A clean, coordinated result for a discerning client.
