wait. so standard pitch of earth for a house is just 100sq.meters? so 2 floor house would average something like 70sq. meters, right? my apartment that i rent with 2 friends while i study is 76sq.m. and rent is 600$
someone said it is 1200+$ in Japan for an apartment...that is a lot. and probably only some 50sq.m at best, right?
and you can't compare houses in USA with houses in Japan. half of them in the warm climate zones of the USA are made from plasterboard and the likes which is cheap and unsafe.
