Four upper floors to be added to 65 Gresham Street
JP Morgan Asset Management has signed off a deal with Mace to deliver one of the largest building reuse projects in the City of London.
The project to overhaul 65 Gresham Street, adding four extra lightweight rooftop floors, comes after a major pre-let deal this week with a city investment firm to take all 400,000 sq ft of space.
The £200m-plus building overhaul will see the building raised in height to 12 storeys, adding external terraces and inset balconies will provide outdoor space on every floor.
Prioritising a reuse first approach, the project will retain more than 70% of the existing building’s structure, with 95% of materials recycled or reused on-site, targeting a 66% reduction in whole-life carbon.
Redesigned building will add around 140,000 sq ft with four new landscaped rooftop floors
Fossil fuel free during construction and operation, the building will incorporate air source heat pumps for heating, cooling and hot water generation.
