Box House is one of 10 pioneering self-built houses, built at Graven Hill in Bicester: The Graven Hill development is of national significance, a ‘vanguard’ project helping to meet the government’s commitment to doubling the number of Custom & Self Build Homes by 2020. Box House featured on the new Grand Designs spin-off (known as Grand Designs: The Street) in April 2019. As a direct response to this brief, Studio Bark developed an innovative system of flat-pack timber building boxes, known as U-Build. The box modules were simple enough to be built by the client, but complex enough to perform the many requirements of a building envelope, and meet the stringent tests of the structural warranty provider. It is modular, flexible and can be ‘nested’ onto standard sheets of plywood, resulting in minimal wastage.
