1-3 Grosvenor Square

Reconstructing facades with an independent steel frame restraint system

1-3 Grosvenor Square, also known as MacDonald House which used to serve as the Canadian High Commission, is being demolished, re-built and restored to its former physical beauty whilst changing the use of the building into 48 residential units, associated ancillary leisure facilities, car parking and a restaurant.

The new development of the Grade II listed building provides residential use over 7 levels above ground and 3 storeys of new basement space. The existing facade were carefully dismantled so the materials could be retained and reused in the facade reconstruction.

Working with PAYE stonework we provided the design and detailing of the reconstructed facades, including designing an independent steel frame restraint system and limiting the need for movement joints. The overall length of both facades were 105m and over 2km of stainless steel used as the restraint system.

The overall project is due to complete at the end of 2020.
