I think I specified USD = US dollar, but that is cheap, our neighbor got an offer of USD 160000 for a house of about 180m2. That was with ceramic tiles, but afaik it’s not that much cheaper even if you chose cheaper materials, I think the cheapest was about USD 120000.

Edit

I have been misinformed, I looked up prices and you can get a new roof for a 100m2 house approximately 1000 ft2, for about USD 10000.
