18b Charles street is an impressive Arts and Crafts Edwardian period Grade II listed building located in one of London's most prestigious areas. The site consists of a twentieth century property located within the Mayfair Conservation area on the corner of Charles Street and Chesterfield Hill.

The proposals was to sensitively convert the current multi let office into 5 residential luxury
Apartments (spread over 7 floor levels) and to bring the building back to its original state as a
Proud and Prominent corner property in Mayfair.

This brief has been fulfilled by removing attachments added for its commercial function and with careful conservation and refurbishment of its major internal and external features. In addition to this an extension to the rear and a mansard roof at third floor level, both designed to be subservient and respectful to the existing building, have increased the habitable area and private amenity has been gained in the form of a balcony terrace to flat 5. The refurbishment of the existing alcoves within the lightwells provide secure dedicated off street storage facilities such as undercover cycle parking and refuse storage.
