Designed by its owner, Robert Bruno, the Steel House is built entirely out of steel and weighs at about 110 tons. That’s a lot of steel, if someone was to sell the house for raw material alone, they’d probably fetch something around $30,000. But that’s just small change for a project that Bruno has worked on for 28 years, ever since he saw a similar sculpture and thought it would be nice to actually walk through something like it.

The interior of this unusual house built in Lubbock, Texas, is also made out of forged steel and it was all made by hand.
