The most expensive home on the Washington housing market belongs to a Bellevue residence, with a price tag of a whopping $79 million.
Built in 2016, the six-bedroom, 10-bathroom home is situated on the Lake Washington waterfront and is listed with an undisclosed address, according to Zillow.
“A one-of-a-kind presence on Lake Washington, Triptych is the vision of renowned architect Tom Kundig,” Zillow stated. “Kundig’s iconic details are highlighted throughout the design, materials, and interior features. A home conceived for entertaining — both large and intimate — integrating art, nature, and exceptional panoramic views.”

The 16,284-square-foot home sits on a 3.37-acre plot of land with a six-car garage, an in-ground pool, and a more than 10,000-bottle wine cellar.
Paired with the more than 434 feet of flat Lake Washington waterfront, the home includes a “lakeside pavilion” equipped with a seating area, kitchen, and fireplace, a short distance away from the boat dock.
Residents of the two-story home can navigate the space by using an elevator to access several upstairs bedrooms, the full-scale kitchen, and the spacious media room.
“All the luxury amenities one expects are present,” Zillow stated. “Triptych offers a once-in-a-lifetime opportunity to own an eminently livable, architecturally significant Tom Kundig masterpiece in an unmatched setting.”
Other essential features include a rooftop deck, hot tub, spa, sauna, large detached gym, and a lush garden space filled with fruit trees and elegant sculptures.
The home’s architect, Tom Kundig, is a University of Washington (UW) graduate who has spent four decades designing award-winning architecture, including the Burke Museum in Seattle, the LeBron James Innovation Center for Nike, among various other restaurants, residences, and wineries across six continents.
