The clients, from Japan and China, and their young children were looking for a flexible outbuilding to provide space for entertaining, working, and accommodating guests on overnight stays. Cave Coop designed a garden building incorporating a Japanese style tea house in the garden of a suburban Kingston upon Thames home. The 36m² outbuilding contains the wooden room surrounded by semi-opaque sliding doors surrounding Tatami mats and a sunken table. There's an office containing shelves full of games and a deep-toned bathroom.
