33 Grosvenor StreetImages1 / Information
Location London W1
Status Completed 2015
33 Grosvenor Street is a grade II listed part-heritage refurbishment part-extension project in the heart of Mayfair. Considered to be a fine example of an Edwardian residence, the building had fallen into disrepair prior to purchase by Grosvenor. Their aspiration was to create a next generation townhouse office building, exceeding tenant expectations through innovative design, specification and building flexibility.
Squire and Partners’ design integrates new and existing elements of the building to create a cohesive visual narrative. Their heritage sensitive approach retains and enhances historic features, while integrating discreet servicing and a contemporary extension.
The building segments are linked by a central spine, glazed to maximise visual connections between heritage and new build areas. Details employ common design motifs and materials to tie the scheme together, whilst contemporary lighting highlights original features.
Externally, a new build extension is designed to be aesthetically unobtrusive, clad in hand cut Costwold Buff brick. Careful detailing such as GRC window linings offer a contemporary take on traditional white window reveals typical of the area.
