The project is a complete remodelling of a two-bedroom 1980s basement apartment in Chelsea. With both light and space in short supply, the client asked for a piece of architecture that possessed the spirit and sophistication of traditional and contemporary Japanese architecture without reverting to pastiche. The building is located at the lowest level of a 6 story Victorian terrace. The apartment was stripped back to the structural frame in order to optimise the design in terms of ceiling heights and construction tolerances, which also included removal of the existing screed. To make the most of the south-facing courtyard garden, the windows were made full height, continuous between rooms and the rear French doors enlarged to bring the outdoor spaces into the flat. Additionally to further emphasise the fluidity of the space between inside and out, all of the materials we chose form a palette of muted, natural colours that reference the Japanese aesthetic of Zen palaces. The materials are colour true with a matte or satin brushed finish, so that as the apartment ages the finishes will develop a patina from use, ageing gracefully over time. It is our hope that by rethinking the flat in this way, it will ensure that it’s lifespan will be extended for at least another 100 years.
