This is a new three-story wooden research building in Sumitomo Forestry's Tsukuba Research Institute, and was designed as a one-hour fireproof building. The structure consists of load-bearing walls made of radiata pine (LVL) using the post-tension construction method developed by Sumitomo Forestry, and post and beam made of larch laminated wood. The load-bearing walls are arranged in an S-shape in the longitudinal direction of the entire building. The inner courtyard is enclosed by post-tensioned wall columns made of 1,200 mm square, 300 mm thick LVL blocks made of radiata pine, stacked in a checkerboard pattern.
