The Japan Wood Products Export Promotion Council has made up four models of wood houses based on the Chinese wood building standard.
The models correspond with the Chinese needs of Japanese species like cedar, cypress and larch to differentiate from 2x4construction. The Council is now planning to promote sales of domestic wood products and wood house to China.
At the moment, there are four model plans. M1 type has two stories with floor space of 170-300 m2 and M2 type has two to three stories with floor space of 170– 300 m2. M1and M2 are both medium grade specifications.
J1 type has two stories with floor space of 200-300 m2 and J2 type has two stories with floor space of more than 300 m2. 1 and J2 are both high grade specification. They are different from Japanese houses, with much higher height of ceiling like 3-4 meters on first floor and 2.4-2.5 meters on the second floor.
The Chinese wood construction standard allows to build up to three stories and the committee is now discussing for higher wood multilayer building. They are also interested in wood multilayer buildings in North America and Europe including use of CLT.
