Marylebone Square

Located in the heart of Marylebone, this is a self-contained building in one of London’s most sought-after locations. The building features private lateral apartments in a beautifully designed, mixed-use building on the site of the former Moxon Street carpark.

Amenities include retail shops, restaurants, and community facilities. The basement offers residents with parking facilities.

We worked with SEC to supply our TerraSmart Rail Paving System both internally and externally.

On the external balconies of the project, we had to overcome wind-uplift, so we carried out a survey and used a fixing mechanism to secure the system against any adverse weather conditions.

Wind uplift occurs when strong winds encounter a building and are forced up and over it. This accelerates the wind and creates a pocket of negative pressure above horizontal surfaces, such as balconies and terraces.

This negative pressure exerts a suction effect on the surface, lifting paving and decking from the supporting substructure and causing significant damage.

We have a dedicated article on this topic if you are interested in reading more about it.

On the internal walkways of the building, our TerraSmart Rail was transported off-site where it was fixed to a steel frame. Our non-combustible joist-support RD-FR pedestals were spot-welded onto the main steel and the DS joists fixed to that. This was aligned with the overall height build-up for the 600x1200mm pavers on the internal gantries to be sitting onto. This is how the installers achieved the seamless integration between internal and external spaces of those areas.

TerraSmart® Rail is made up of super-strong, 100% recyclable aluminium joists, which overlap to create a lattice framework, offering the maximum possible level of support for the paving surface. The system is fully non-combustible, achieving a Euroclass A1 fire rating.

The finish of the internal areas at ground level, where no fire rating was required, featured 40mm granite pavers supported by our self-levelling adjustable RPA paving pedestals.

Kier was the main contractor of the project which completed in 2023.
