In respect of the Conservation Area, the Weymouth Street facade has been retained and refurbished so that it blends virtually seamlessly with the surrounding vernacular; however bright brass cladding dramatically caps the building, containing two new levels of penthouses. This cladding fully envelops the rear elevation, where the building has been strikingly extended horizontally and vertically to provide 12 new luxury apartments, exploding with punched balconies that cantilever out from internal living spaces.

Brass was chosen for its sustainable and distinctive qualities; natural oxidisation will cause the totally recyclable material to weather over time and provide a depth and character to the building. Each panel will patinate differently, but this process has been enhanced by mixing a different ratio of copper and zinc components to achieve colours ranging from golden yellow at the rear of the building, to a russet brown on the new upper levels that are glimpsed from Weymouth Street. The colours complement the surrounding architectural palette and will gradually tone down to echo the shades of the surrounding buildings.

This cladding system has been wrapped around a concrete-frame structure. The new enclosed balconies play with the verticality of the neighbouring blocks, and the pattern of this facade has been repeated within the balcony frames themselves, perforated into the screens to create a Mondrian-like design which casts intricate, artistic shadows.
