WATCH: The story of the UK’s most sustainable heritage homes

After a final review from BRE, the sustainability benchmarking body, Grosvenor’s 119 Ebury Street scheme has secured the first ever BREEAM Outstanding rating for a listed residential retrofit.

It’s a big deal for both Grosvenor and the wider UK housing market, and proves that traditional, heat-guzzling period properties can be turned into lean green machines with some clever alterations and the right kit.

The three apartments created from the former rundown hotel in Belgravia ended up scoring 89.2, 90 and 90% on the sustainability scale – the highest ratings to date for a BREEAM Domestic Refurbishment.

The flats – converted in collaboration with Westminster City Council, Historic England and David Morley Architects – have been designed to reduce carbon emissions by more than 75% from the property pre-development, a full 30 years ahead of the national target of 80% by 2050.

Victoria Herring, Director of Refurbishment and Retrofit, London estate, Grosvenor Britain & Ireland, said: “Meaningful carbon reduction is a huge challenge for Grosvenor, the wider property industry and the country as a whole. That is why we’re taking these measures and we hope 119 Ebury Street will make a valuable contribution that we can apply across our estate and that others can learn from too.”

David Morley Architects’ Head of Environmental Design, Jennifer Juritz: “This exemplary retrofit project has been a fascinating creative challenge from conception to completion. The opportunity provided to us by Grosvenor and Westminster City Council has allowed us to reimagine a neglected property of historic significance into highly sustainable 21st century homes. 119 Ebury Street shows that with sensitive design, innovative low carbon solutions can be combined with historic fabric enabling our city’s heritage of older buildings to remain protected whilst contributing to a modern environmentally conscious built environment that is well suited to contemporary lifestyles.”
