Bill Gates House, Xanadu 2.0: Details

Bill Gates House Location Map

• The Bill Gates house sits at 1835 73rd Avenue NE, Medina, Washington 98039 — one of the most exclusive zip codes in the Pacific Northwest.
• Neighborhood: Medina is a small, affluent city on the eastern shore of Lake Washington, directly across the water from Seattle. It borders Clyde Hill and Bellevue to the south and east, and sits within King County.

The property occupies roughly 5.15 acres of prime lakefront real estate, with 300 feet of private Lake Washington shoreline. Medina’s location offers sweeping westward views toward Seattle’s skyline while maintaining the quiet, forested character of the Eastside.

Bill Gates House, Washington: A Tour of Xanadu 2.0

I will be honest about what strikes you first when you study this property from every available photograph and architectural record: it does not look like what you might expect from the world’s most sophisticated private home. The earth-sheltered, Pacific Lodge-style structure blends deliberately into the hillside. The building is simultaneously massive and understated — as if it is trying not to announce itself to the lake below.

Then you look closer, and the scale becomes clear. At 66,000 square feet, Xanadu 2.0 is approximately three times the size of the White House’s usable residential space. The estate took seven years and an estimated $63 million to build, and it is equipped with technology that was genuinely ahead of its time when completed in 1997 and has been continuously updated since.

Bill Gates House Inside: A Room-by-Room Tour

Exterior Design and Architectural Highlights

The Xanadu 2.0 estate, crafted in a Pacific Lodge style, blends natural wood and stone with wide roof overhangs and a horizontal, earth-sheltered design that integrates into the hillside for energy efficiency. It boasts 300 feet of private Lake Washington shoreline, a pier and boat dock, and lush landscaping for privacy. Additional features include underwater music speakers in the swimming area and a high-end perimeter security system, combining luxury, seclusion, and innovation.

Grand Entrance Hall and Smart Home System

The entrance to Xanadu 2.0 sets an immediate tone of quiet precision. Every guest to the home receives a special electronic pin on arrival the pin communicates with sensors throughout the house, automatically adjusting lighting, temperature, music, and artwork displays to match each guest’s preset preferences as they move from room to room. The system reportedly cost around $80 million to design and install, making the technology alone more expensive than most mansions in the country.

The Library

One of the most celebrated rooms in the Bill Gates house is the 2,300-square-foot domed private library. It features a hidden bar behind a panel of wood and contains a complete collection of Leonardo da Vinci’s scientific writings the Codex Leicester, which Gates purchased at auction in 1994 for $30.8 million, is kept here.

The dome ceiling is inscribed with a quotation from The Great Gatsby: “He had come a long way to this blue lawn, and his dream must have seemed so close that he could hardly fail to grasp it.”

Home Theater

The 20-seat private theater features a reception area with a full concession-style setup and is equipped for professional-grade film screenings. The theater’s audiovisual system is fully integrated into the estate’s central smart home network, allowing seamless control of every element of the viewing experience. 

A similar dedication to immersive design can be seen in other landmark estates such as the Ira Rennert Hamptons House, where private entertainment spaces define the character of the home.

The Trampoline Room

Perhaps no room in any private residence in America is better known for sheer unexpectedness: a full-size indoor trampoline room with a ceiling high enough for serious use. Gates has discussed his love of trampolining publicly, and the room has become one of the most frequently cited details in coverage of the estate. It is a reminder that even the world’s most sophisticated home contains spaces designed purely for joy.

Swimming Pool

The indoor-outdoor 60-foot swimming pool is equipped with an underwater sound system that pipes music directly through the water. The pool connects to a pool house with locker rooms and adjoining outdoor entertaining spaces overlooking the lake. The integration of the pool with the estate’s smart systems means temperature, lighting, and audio are all controlled from a central interface.

Garage and Vehicle Collection

The 23-car underground garage is among the largest private garages attached to any residential property in the United States. Gates has maintained a notable vehicle collection over the years, including a Porsche 959 that famously sat in a US Customs warehouse for years because it did not meet American emissions standards a situation that eventually helped change federal importation law.

Outdoor Spaces

The grounds of the estate extend across 5.15 acres and include manicured gardens, mature Douglas firs, a sandy private beach, and direct access to Lake Washington. The shoreline is equipped for water sports and features the private boat dock. Evening lighting across the grounds and the dock makes the estate particularly striking viewed from the water.

What Makes Bill Gates’ Xanadu 2.0 Genuinely Special?

The Xanadu 2.0 compound succeeds by solving a genuinely difficult problem: how do you build a home that is simultaneously a private sanctuary, a technological showcase, an art gallery, and a functional family residence without it feeling like a museum or a corporate campus?

The answer, in Gates’ case, is the restraint of the exterior combined with the richness of the interior. The Pacific Lodge architecture grounds the building in its Pacific Northwest landscape. The smart systems serve the people inside them rather than performing for visitors. The library, the art, the theater each space has a clear purpose rooted in genuine personal interest.

The overall result is a residence that reflects its owner: methodical, purposeful, and more interesting the closer you look. For another example of a residence defined by its owner’s personality, see our coverage of Jeffrey Altman’s house.

Bill Gates House Zillow and Public Records

The Bill Gates house does appear in King County public property records under the address 1835 73rd Ave NE, Medina, WA 98039, though detailed interior imagery is not publicly available through standard real estate platforms. King County Assessor records confirm the 66,000-square-foot figure, the 5.15-acre parcel size, and assessed valuations that have risen steadily over recent years as Eastside Seattle real estate values have surged.

Zillow and Redfin both show the parcel in their databases, but listing photographs are limited to satellite and exterior views due to the estate’s extensive privacy measures. Public records also confirm that Gates has made various permitted improvements to the property over the years, consistent with the ongoing technological upgrades the home is known for.

Bill Gates House Lake Washington: The Setting

The Lake Washington shoreline is the defining feature of the Bill Gates house site. Lake Washington is a glacially carved freshwater lake approximately 22 miles long and up to 4 miles wide, stretching between Seattle to the west and the Eastside cities of Bellevue, Kirkland, and Medina to the east.

The lake was significantly lowered in 1916 with the opening of the Lake Washington Ship Canal, exposing new shoreline that became some of the most desirable residential real estate in the Pacific Northwest. Gates’ 300-foot stretch of that shoreline faces west, providing afternoon and evening light across the water toward Seattle — one of the most coveted orientations on the lake. Water temperatures support year-round use of the private beach and dock.

• Given its one-of-a-kind technological infrastructure and custom-built nature, any future sale would represent one of the most significant residential real estate transactions in American history

Rumors of a sale have circulated periodically in tabloid coverage, particularly in the context of Gates’ 2021 divorce from Melinda French Gates, but no listing has materialized. Medina property records continue to show the estate in Gates’ ownership.
