Located within a Conservation Area, in depth negotiations were required with the local planners to successfully secure this sensitive planning approval. In addition to creating a full basement extension beneath the existing house and garden, the roof has been extended and the internal layout has been re-planned at each level. The house benefits from an unusually large garden for the location. The design optimises this asset. Unlike many basement excavations, the design successfully links the new basement to the garden, and also to the ground floor main family kitchen living area via an internal feature stair.
