Meticulously restoring Britain’s most expensive terrace to its original residential use.

Silk House was the Evening Standard’s Best New Luxury Home in 2011

We worked closely with Oakmayne Properties, English Heritage and The Crown Estate to rebuild and restore the Grade I listed Cornwall Terrace, which overlooks central London’s Regent’s Park, to its original residential use. The front elevation has been fully restored, while behind the listed façade eight new luxury homes have been created. The low floor to ceiling heights in the basements and top floors, which would have originally been used as service quarters and ancillary accommodation, were unsuitable for use as high-end residential spaces. We redesigned sections of the roof and added two extra floors below the original basement to increase the floor-to-ceiling-heights and allow for a contemporary use of the space.


The building was originally designed by Decimus Burton under the supervision of John Nash, and completed circa 1820 as part of Prince Regent’s scheme to develop grand housing in Regent’s Park. The property was severely damaged during the Second World War and subsequently used as offices from 1975 until it was bought by Oakmayne Properties in 2007. Our design carefully preserves original architectural features such as marble staircases, period fireplaces, cornicing and other decorative detailing. The houses feature state of the art technology including air cooling, IT and audiovisual systems and hydraulic lifts.
