Mace to Lead Landmark Retrofit Scheme in London
14 April 2025 | Updated 16 April 2025
 

Mace has been appointed to deliver one of the largest building reuse projects in the City of London, at 65 Gresham Street.

The extension, designed by Squire & Partners, will include over 36,800m² of Grade A office, retail and ancillary spaces. Four new floors will be added to the existing eight-storey building, with terraces and inset balconies.

More than 70 per cent of the existing building's structure will be retained, with 95 per cent of materials recycled or reused on-site. A whole-life carbon reduction of 66 per cent is being targeted, as well as a 100 per cent increase in biodiversity net gain.

The scheme received planning approval in January 2024. JP Morgan Asset Management secured a pre-let agreement with Squarepoint, a global investment management firm, for the entire 400,000 sq ft office space.

Ged Simmonds, Managing Director Private Sector, Mace Construct said: ‘’This ambitious retrofit project exemplifies Mace's commitment to sustainable construction, showcasing innovative solutions that reduce environmental impact and set the standard for the next generation of sustainable offices.

“In the past five years we’ve seen a growing trend in the City of London for sustainability-driven, reuse-focussed office developments."  

65 Gresham Street is due for completion in 2028.
