Holbein Gardens is a redevelopment and one storey extension of a 1980s office building near Sloane Square, setting a new benchmark for sustainable workplaces and Grosvenor’s first net zero office development. The project centres on retaining the existing four-storey structure, innovative re-use of materials and the introduction of extensive greening.    

Designed by Barr Gazetas, it is the first scheme to apply Grosvenor’s Sustainable Development Brief, which is based on best practice from current certification schemes and Grosvenor’s sustainability targets.  

All contractors and advisors on the project have been challenged to help Grosvenor deliver against its goals of net zero carbon, zero waste and a significant biodiversity gain. 

As a result, the development of Holbein Gardens saved 59 tonnes of carbon by retaining the façade, the equivalent of 557 return flights from London to Amsterdam, reused 13.5 tonnes of steel, trialled a range of other low embodied carbon products and diverted 99.5% of strip out waste from landfill.  

Holbein Gardens has achieved BREEAM Outstanding, NABERS 4.5* certification and is targeting an EPC A rating.
