@kitty63 Yeah could be worth it if you can "plan" your house and change what you want before it's built. If you do plan to stay in the long run it could be convenient. Maybe it will have better sound proofing than the average house?
@kitty63 Yeah exactly. The situation in Japan is different than in Europe or america.
I'm guessing new would be too expensive for the same area/surface as an older one?
