This project involved the complete remodelling and extension of a five-storey Victorian townhouse in Chelsea, including the excavation of an additional basement level beneath the footprint of the house, vaults and most of the rear garden. The property had been extensively 'chopped and changed' over the years, including various 1970s accretions. The opportunity therefore existed, planning permitting, for a complete internal rebuild. This was grasped to the full, and only the front facade and roof now remain of the original.
