NACWL is involved on this exciting project at Sussex House which involves the facade refurbishment on Upper St. Martin’s Lane and Long Acre frontages, and a sixth and seventh floor roof terrace with glazed facade, architectural balustrade and canopy.

The site is located close to Leicester Square within the City of Westminster. It is trapezoidal in shape over an area of 207m2. It is bounded to the west by Upper St. Martin’s Lane, and to the south by Long Acre. It is the most prominent of the corner buildings at this central London intersection.



The majority of the facade refurbishment will be the installation of the Linit cast glass cladding product. This is a system designed and patented by Ian Ritchie Architects. The glass is produced in Germany and the connections to the structure are made through a variety of bespoke, extruded profiles.

In addition to the Linit, NACWL will be designing and installing vertical glazed window ribbons and incorporating decorative Sto Verolith panels, reaching from 2nd floor to the roof level.
At the ground and 1st floors, NACWL will install a combination of retail glazing and doors, framed with decorative anodised profiles. Linit will be used to clad the columns at these levels.
The proposed design will uplift the quality of the existing offices above and create a desirable retail space at this exceptionally accessible site.

Osborne commented on the project: “Overall, the design proposal has adopted an approach for sustainable development that encompasses environmental, social and economic aspects and delivers a long-lasting healthy and comfortable atmosphere for the future users. We look forward to working closely with NACWL to deliver a successful project and develop our professional relationship moving forward.”
