Gates didn’t leave a stone left unturned when he thought about the architecture of Xanadu 2.0. He used Bohin Cywinski Jackson Architects and Cutler-Anderson Architects to collaborate on this extensive project. Neither of the architecture companies have photos of the inside of the house posted, for the family’s privacy.
The house is built into side of a hill, which is called earth sheltering. Earth sheltering will helps maintain a steady climate and reduces heat loss. Being built into the hillside, Gates took extra precaution and built some of the reinforcement much thinker than building codes require.
