Squire & Partners is retrofitting and extending 65 Gresham Street to deliver one of the largest building reuse projects in the City of London, comprising circa 36,800m² of Grade A office, retail and ancillary spaces.
Four new lightweight floors will extend the existing eight-storey office building. Taking inspiration from the Gothic architecture of the nearby Guildhall and its brutalist modern extension, proposals offer a contemporary response to the surrounding architectural context.

Avoiding demolition through large scale reuse and regeneration, the world class, all-electric office building will target a 66% whole life carbon reduction and operational carbon at 12% lower than the 2022 GLA criteria. 70% of the existing building’s structure will be retained and 95% of the materials will be recycled or reused.
The creation of external terraces and inset balconies will provide outdoor space on every floor. At ground floor, the expansion of existing entrances and relocation of retail space will activate the Aldermanbury streetscape, whilst the repurposing of an existing vehicle ramp will create a new cycle entrance leading to generous end of journey facilities.
