15 Facts About Bill Gates House


The Guest House

The 1,900 square foot guest house is a mini version of the main structure. It only has one bedroom, one bathroom, and one fireplace. This is one of the smaller structures and is almost hidden underground. Since this was one of the first buildings to be completed, Gates used it to test the technology that was designed for the main house. He spent a lot of time in this house writing his book, The Road Ahead.
