Tokyo Institute of Technology (TIT) was originally located in Kuramae, it was moved to the site of present Ookayama Campus after the Kanto Earthquake of 1923. The 800-seat auditorium was built to commemorate the seventieth anniversary of the school’s funding. The floor of the auditorium follows the slope of the site, but the exterior envelope disguises the building’s bulk. Daylight is introduced from one side of the space and dispersed by a wood lattice screen. An interesting combination of different textures is provided by the wood screen, concrete, glass and brick.
