7-8 St James's Square

An unusually complicated city centre project, involving significant ground works and temporary works and a highly varied superstructure, plus the retention of a listed building. The site occupies a prominent position on the north side of St James's Square on the corner of Duke of York Street and returns into Apple Tree Yard. It includes a Grade II listed building, 7 St James's Square designed by Sir Edwin Lutyens, and lies within the St James's Conservation Area.

No.7 has also been restored for use as a single grand residence as originally intended by Lutyens. Our scope was therefore not to refit the house internally, but to form a new two storey basement below the rear of the existing building for a future underground car park and swimming pool and form a new ground floor courtyard above.

Completed 2015.
