CLT plates can bear compressive and tensile forces in both orthogonal directions. Based on this strength characteristic, we realized large spaces of 7.5 m wide and 7.5 m high for the first time in Japan with a wooden folded plate structure using only 90 mm thick CLT, creating rich, comfortable, and unique interior spaces. The high thermal insulation performance of the CLT walls, combined with the moderate thermal capacity of the wood, has resulted in a space that is three times larger than a conventional office, but consumes about half the energy with the same floor area, resulting in significant energy savings and a low-carbon footprint.
