Flat Extension & Full Luxury Refurbishment — Conservation Area, Westminster MTA won planning permission from Westminster City Council for an extension to a two-bedroom flat in Belgravia — one of London's most prestigious residential addresses and one of Westminster's most carefully controlled conservation areas. Delicate negotiations with Westminster's conservation officers secured permission for a new bedroom, en-suite bathroom and conservatory addition, sensitively designed to complement and enhance the existing 1930s building in matching style and finish. The conservatory is the centrepiece of the project — creatively designed with a large sliding rooflight that opens the space fully to the elements, flooding the conservatory and surrounding rooms with natural daylight and direct sunlight. When open, the boundary between inside and outside dissolves entirely, creating a uniquely generous living space in what is one of London's most constrained planning environments. The flat was successfully extended from two to three bedrooms while retaining the existing large terraces. The full refurbishment transformed every room — new bathrooms, new kitchen, and considered finishes throughout to create a light, contemporary feel that respects the character of the existing building. Built-in storage was designed for all rooms and the main hallway, maximising the sense of space and organisation throughout. The result is a beautifully resolved luxury flat that feels significantly more generous than its original footprint suggested.
