J.P. Morgan Asset Management has appointed Mace to carry out a building reuse project at 65 Gresham Street in the City of London, UK.
This project will deliver more than 36,800m² of Grade A office, retail, and ancillary spaces, with a focus on sustainability.

Over 70% of the existing structure will be preserved while 95% of the materials will be recycled or reused on-site. This strategy seeks to cut the building’s whole-life carbon by 66%.
The building will be fossil-fuel-free both during construction and operation, utilising air-source heat pumps for heating, cooling, and hot-water generation.
The project will also involve the addition of four new lightweight floors to the existing eight-storey building.
External terraces and inset balconies will offer outdoor areas on all floors. The redesign also includes expanded entrances and relocated retail spaces.
The site’s sustainability efforts are expected to raise biodiversity net gain by more than 100%.
The City of London Corporation approved the 65 Gresham Street project in January 2024.
The project team comprises Squire & Partners as the architect, with Buro Happold handling structural engineering, ARUP overseeing services engineering, and Murphy Facade Studio tasked with facade engineering.
Additionally, Gardiner & Theobald is the project manager, with DP9 as the planning consultant, Turner & Townsend Alinea managing cost consultancy, Gustafson Porter + Bowman as the landscape architect, and Longevity consulting on sustainability.
Mace, a construction company, operates in markets across the globe.
Last month, it was selected for the £140m ($181m) extension of Pier 6 at London Gatwick Airport, with completion expected in 2027. This project will introduce eight new aircraft gates directly adjacent to the runways.
Mace is also redeveloping the Great Hall at Imperial College London. The retrofit team will overhaul the 4,230ft² Great Hall within the Sherfield Building, with completion of the project due by mid-2026.
