- The average house in the U.S. is 2,700 square feet, according to the National Association of Home Builders. If that's a one story, it would run you about $640 million.
- The White House is about 55,000 square feet, with six stories. Counting only three of those stories (the maximum of the graphic), that means a pricetag of more (probably a lot more, with the extra stories) than $18 billion to put into orbit.
- Bill Gates' home is 66,000 square feet. Again, counting with the maximum three stories, that's almost $22 billion.
