Amazing House (6 pics)
This house is called "The Subterranean Mansion" and it's located in England. It's on sale for £2,000,000.The house is not that big. There are several bedrooms, WC's, etc. But there is something that makes it one of the most daring & innovative houses ever built. Do you see this round hole in the bedroom wall? Any ideas what it is for? Just take a look at the second photo.
