This site is located at Torigoe, which is between Asakusa and Akihabara, in the old downtown area where there are many small factories. The client requested a small office and his wife is planning on operating a small gallery in the area. Second-hand containers were used, the aesthetics of the worn-out containers fitting with the surrounding factories. A 40-foot marine container has one hatch on the gable side and is normally picked up from outside. The direction of the hatches was planned so as to open from the inside, and two containers were cut and stacked.
ISO (International Organization for Standardization) marine containers that circulate widely in the world are not allowed to be used as a main structure, because the Japanese Building Standards Act requires JIS (Japanese Industrial Standards) materials for structure. Therefore, the architects made the container house with an outside-steel-frame, making a “fake” container house which fits JIS in the Japanese Building Standards Act. To preserve the worn-out container's appearance, a timber frame was built inside, treating the container as a skin, and the timber as the structure, making a “legal container house,” but also a safe structure that resists earthquakes. This project has inspired thinking about ways to reuse scrap marine containers in order to reduce the excessive worldwide stock.
