This private training center has 2 capsule-hotel and 3 tatami-style buildings. They are positioned with various angles of axis and all the rooms have a view of the Tokyo Bay, each one becoming a space like a ship's cabin. The client requested guest units that had the possibility of future relocation or addition. While clearing these requirements and in order to ensure the necessary dimension for the bedroom spaces with economy, we utilized a wooden structural frame on a standard freight-truck of adequate dimensions.
