A small residential project in hackney uses one digital three-dimensional model as the single source of all project information. The site is an existing 45m2 maisonette terrace conversion distributed over three floors in the heart of the de Beauvoir conservation area. Due to the conservation area restrictions, the designer deliberately decided to concentrate on the reorganisation of the interior space and its relation to a split-level garden on the roof, offering intimacy and privacy as well as unobstructed views to the city of London. The external treatment only hints at the less orthodox internal arrangement. The roof garden is sited on the two shifted bedroom nests, resulting in one section of the garden being at lower elevation, creating a more intimate and private space or outdoor room. The other garden is higher, with a lower parapet allowing for an open view of the skyline of London.
