Luxurious remodel behind traditional stable mews facade, within Mayfair Conservation Area. The scope included lowering the existing Lower Ground floor, replacing all the internal floor joists with ‘posi-joists’ to accommodate new services, and connecting the new floors with a beautiful, elegant new staircase. We also constructed a 2-storey extension to the rear, with a roof terrace, accessed from the master bedroom, and extended into the loft space, to create a new family room and private roof terrace at the top of the house. This project was carried out as a development, and sold within a week of going to market.
