The concept for this striking penthouse - situated within a three-storey house, built in 1889 - was to strip everything back to its essential quality. All existing interior walls were removed and a steel A-Frame introduced to achieve a 7m double height, column free space.

A mezzanine floor with a glass balustrade forms the sleeping area; below this three large folding walls enable the open plan format to be subdivided into a series of smaller, more intimate spaces.

As the exterior fabric of the building is protected by an historic preservation order, the project's new glazing complements the fenestration of the building as a whole.

The visual impact of technology is kept to a minimum despite there being a comprehensive computer controlled heating and lighting system. This, among other things, delivers fourteen different illumination scenarios via a series of bespoke lamps. The apartment’s indirect lighting is subtly integrated into the full-length cupboards and window niches.
