This singe storey rear extension is one of the most modest yet one of the most challenging projects designed by our company. Clients approached us with a request to design a Ground Floor level bedroom with an En-suite. The host dwelling is Grade II listed in Pimlico Conservation Area; therefore finding a common ground with conservation officers was one of most important parts of the project. The design both externally and internally is blending well with the main character of the building and immediate neighbourhood.
