As a certain fictional FBI agent would say, we want to believe. Why not? The Underground Home was a 12,000-square-foot, totally underground house built in the aftermath of the Cuban Missile Crisis, as Narratively reported in 2012. With an air filtering system its makers advertised as able to filter fallout particles, the Underground Home tapped into American fears of the times. In addition, the home had 10 rooms, windows made of screens that could show different scenes, and a Steinway piano. The Underground Home was both weird and baller.
