Grosvenor Crescent Mews is part of The Grosvenor Estate, in the Belgravia Conservation Area of Westminster.

Walter Lilly converted and extended an existing two-storey garage and flats on the Mews, into one prestigious three-storey, four bedroom residence.

Works included the addition of a third floor, complete with slated roof to the rear and lead mansard to the front elevation. The existing façades were cleaned down and restored, new windows were installed and bi-folding oak doors were fitted in the basement living space.

A highly-specified kitchen with granite work surfaces was fitted, as well a stunning oak staircase and oak flooring throughout.

The finished project is the oldest building in the UK to obtain a rating of ‘Excellent’ in the BREEAM EcoHomes Environmental Assessment.
