The Vehicle Assembly Building (VAB) - the largest one story building in the world. At 525 feet (160.0 m) tall, 716 feet (218.2 m) long, and 518 feet (157.9 m) wide, it encloses 129,428,000 cubic feet (3,665,000 cubic metres) of space. Maybe it should be named the VBB (Very Big Building). Photo by Jim Lovett
