Together with number 48, these two stuccoed buildings with mirrored-angled entrance doors, form the central pair of an important terrace of houses in central London. Designed by Robert and James Adams and built in the 1770s as a single occupancy residence. It remained as such until the 1930s when it was converted to medical consultancy rooms and flats. In the 1980s an extension was built on the lower ground and ground floors to provide additional office space. More recently the building housed a 370 sqm gallery exhibiting contemporary Chinese art.
As it stood the building comprised office accommodation of the lower ground, ground and 1st floors, with residential on the 2nd, 3rd and 4th floors. The brief was to provide a scheme to redevelop the building for single residential occupancy in the 21st Century (not the 18th Century). The building is Grade II* listed, retaining many of its’ original features such as the staircase and ornate plasterwork, so strict planning requirements were in place. In order to comply and work with these restrictions the scheme focused on the internal layout and creating additional space below and above. Demolishing the 1980s rear extension would provide a new basement for a swimming pool, additional family rooms, and a garden terrace on the first floor level. Additional basement excavation would provide space for plant machinery, with further space on the main roof for more plant machinery.
