Gates' Washington estate, named "Xanadu 2.0," after the fictional home of "Citizen Kane" title character Charles Foster Kane, spans 66,000 square feet. It also features six kitchens, an enormous library housing expensive manuscripts, a home theater, seven bedrooms, and 18.75 bathrooms, per Business Insider, citing public records.

The mansion, which required 100 electricians and 200 construction workers to build, features plenty of high-tech details. One of these high-tech features includes a sensor system that helps guests monitor and customize the temperature and lighting to their preference.

In addition to the sensor system, the mansion is also equipped with numerous speakers hidden behind wallpapers. These speakers allow music to follow guests from room to room.

The mansion is fitted with over $80,000 worth of computer screens, allowing guests to display their favorite paintings or photographs at the touch of a button.

Outside the mansion, there is a 3,900-square-foot building housing a 60-foot pool. People swimming in the pool could go under a glass wall to come up to a terrace area on the outside. The pool also has its own underwater music system to entertain guests.

The mansion's exercise facilities, spanning a total of 2,500 square feet, include a sauna, steam room, locker rooms, and an indoor trampoline.

Lastly, the property has a 2,300-square-foot hall that could seat up to 150 people for a seated event or 200 people standing up for a cocktail gathering, per US News. One side of the hall features a six-foot-wide limestone fireplace, while another has a 22-foot-wide video screen.
