1-4 Marble Arch (formerly Project Nash) reinvents a 1930s office building creating a unique office led mixed-use building with improved retail at street level.

Given its prominent location as a backdrop to Marble Arch, the proposal ensures the restoration, protection and reinterpretation of the existing historic architectural features. The facade will be retained, carefully and respectfully enhanced, and extended to accommodate an additional office floor.

These facade alterations are intended to be subtle and in harmony with the existing building’s design. The fenestration to the lower levels is expanded within the stone facade, linking the ground and first floors. New shopfronts are designed as elegant insertions into the existing facade with profiled bronze coloured metal surrounds and carefully enhanced stone detailing.

The existing internal structure is replaced, allowing for the creation of approximately 5000 square metres of flexible and significantly higher quality office space over seven floors. The structural alterations also facilitate the occupation of the basement level, further extending the retail potential for a large flagship store.
