Sutyagin House, Russia（俄羅斯蘇特亞金房屋）

Sutyagin House was a wooden house built by Russian businessman Nikolai Petrovich Sutyagin over a time-span of 15 years (starting in 1992). Even though the building had only two stories, the roof spanned 11-15 stories more, making it the world's, or at least Russia's, highest wooden house. In 2008, the tower was condemned a fire hazard and part of it was pulled down by the local government. The remaining four-storey structure ironically burned to the ground on May 6, 2012.
