Roots in the Sky London, UK

Roots in The Sky will be London’s first office building to deliver an urban forest rooftop, and will set a new benchmark for sustainability and the circular economy. The project involves the transformation of a former 1960s courthouse into an all-electric office building that will be Net Zero in both construction and operation.

It will also be the first building in the UK to have an urban forest on its rooftop. The 0.6-hectare area will hold 1,000 tonnes of soil into which will be planted 125 mature trees and 10,000 other plants. On completion in December 2026, the project will provide all building users with cooling shade, fresh air and contact with the natural world. The Roots in the Sky rooftop terrace will also have exceptional views over the capital.

- 41%

Its passive design, use of renewable energy and embedded smart energy management systems will reduce the operational emissions of Roots in the Sky to more than 41% below the UK baseline.

This highly sustainable worldclass workspace project by Fabrix will target the highest environmental certification levels currently available: BREEAM Outstanding, WELL Platinum and Nabers 5*.
