This project is the refurbishment of a large flat in Highpoint in Highgate, London. Berthold Lubetkinís seminal modernist flats of 1935 are Grade I listed, which necessitated delicate negotiations with English Heritage. Twentieth century changes were removed, the old kitchen was converted into a study, and the dining room opened out to become a large family kitchen. New built-in elements in the kitchen, bathroom and study stand out by the use of a range of colours from subtle khaki to flaming fuscia. A new bookcase was designed as the centerpiece of the flat, based on a 1:10-scale model of a cut through the whole block.
