Wedoany.com Report-Apr. 11, J.P. Morgan Asset Management has engaged Mace to lead a building reuse project at 65 Gresham Street in the City of London, UK. The initiative will transform the site into over 36,800 square meters of premium office, retail, and support spaces, prioritizing sustainable design. Approved by the City of London Corporation in January 2024, the project underscores environmental responsibility.
The City of London Corporation approved the project last January.
The redevelopment will retain over 70% of the existing structure, with 95% of materials recycled or reused on-site. This approach aims to reduce the building’s whole-life carbon footprint by 66%. A project spokesperson stated: “Our focus is on creating a sustainable, modern space that meets the needs of occupants while minimizing environmental impact.”
The building will operate without fossil fuels during construction and use, relying on air-source heat pumps for heating, cooling, and hot water. Four lightweight floors will be added to the current eight-story structure, expanding capacity. New external terraces and inset balconies will provide outdoor access on every level, while redesigned entrances and relocated retail areas enhance functionality.
Sustainability efforts are projected to increase biodiversity net gain by over 100%, enriching the local ecosystem. A London-based environmental consultant noted: “This project sets a strong example for balancing urban development with nature.” The design integrates green principles without altering local consumption patterns, focusing solely on construction and operation.
The project team includes Squire & Partners as architects, Buro Happold for structural engineering, ARUP for services engineering, and Murphy Facade Studio for facade work. Gardiner & Theobald manages the project, with DP9 handling planning, Turner & Townsend Alinea overseeing costs, Gustafson Porter + Bowman designing landscapes, and Longevity advising on sustainability.
Mace, based in London, brings extensive construction expertise. Last month, it secured a £140 million ($181 million) contract to expand Pier 6 at London Gatwick Airport, adding eight aircraft gates by 2027. Additionally, Mace is retrofitting the 4,230-square-foot Great Hall at Imperial College London’s Sherfield Building, with completion expected by mid-2026. A Mace representative said: “We’re committed to delivering innovative, high-quality projects that serve communities and clients.”
The 65 Gresham Street project aligns with London’s vision for sustainable urban growth. By preserving existing materials and adopting energy-efficient systems, it creates a modern workspace while reducing environmental impact. The collaborative effort ensures the site meets high standards for design and functionality, benefiting occupants and the broader city.
