Around 1212, Kamo no Chōmei completed Hōjōki, An Account of a Ten-Foot-Square Hut. The hut he describes measured one jō, about three meters, on each side, and was seven shaku, about two meters, high.
The pillars were joined with tenons, and the walls were held with latches. The hut stood on a base frame instead of posts set into the ground. An architectural study of the hut notes that this structure assumes the building will be moved. Its materials were carried on two oxcarts.
