Sutyagin House in Arkhangelsk, Russia

Maybe it's the world's tallest wooden house with 13 stories and a 44 m tall tower. Nikolai Petrovich Sutyagin and his family started the construction in 1992, and finished fifteen years later. In 2008 the city ordered it to be demolished because of fire hazard (wooden structures are limited by law to two stories). What a loss! Here are some incredible strange or wonderful castles and mansions that were built by only one person.

An underground home in Las Vegas, converted from a Cold War-era bunker

3970 Spencer boasts all the comforts of suburban life in Las Vegas, circa the late 1960s: A heated pool (with a water fountain), a four-hole putting course, jacuzzis, a bar, and a dance floor. Then there are more unusual features, like the sky control system—a dimmer that can be set to "morning," "dusk," or "night," which activates the "stars" embedded in the ceiling. Just above them, a thick concrete shell protects this perfect suburban simulacra from impending nuclear doom.

The home was built in the mid-70s by one Girard B. “Jerry” Henderson, an entrepreneur whose company, Underground World Home Inc., specialized in luxury bunkers.
