Combined Residence and Shop in Narrow Downtown Space
Built on a small, narrow block of 4.5m width and about 66㎡ area adjacent to a city-center main street, this “Box House” was planned as a multipurpose residential house with a shop space on the ground floor. In order to provide sufficient internal volume in such a narrow area, 105×105/2mm climbing beams are aligned 455mm apart. In the section that forms the main structure, 105x105mm members are aligned 1.8m apart, which are joined to 105x105mm ridgepoles with connectors which are internally, hidden, allowing for a clean exposed structure while securing the required bearing force. In addition, tie rods to take pressure thrust are aligned 1.8m apart, each end of which is connected to a girt using Node.Fork connectors. The joint strength between the climbing beams and ridgepoles was confirmed by a Stroog.test strength test.
