This is what you can end up with after about 1.3 million US dollars here in Japan (Live in totsuka which is like a 15 minute drive from Yokohama)...
Basically we used to own a house just like the neighbors that you can see in the pics but with the parents getting older the wife wanted to tear it down and build a 2 generation home. (this is semi-common here) So we tore it down and built this concrete home which ran like 500 grand.
Figure the land goes for about the same price and other costs such as the original house and it all adds up to quite a bit of cash for not a whole lot of house.
and i guess i broke the thread...hmm those are some big pics /
