This project has involved the complete remodeling and extension of a five-story Victorian terraced house in Chelsea, including the excavation of an additional basement level beneath the footprint of the house, front vaults and most of the rear garden. The house had been extensively ‘chopped and changed’ over the years, including various 1970s accretions, so the opportunity existed, planning to permit, for a complete internal rebuild; only the front façade and roof now remain of the original.
