A lakefront mansion listed for more than $30 million in a Chicago suburb has reportedly set a record with its sale price after more than a year on the market.

The Winnetka estate known as the “Windsor House,” a 2.3-acre property listed for $35 million, has officially sold for $31.25 million.

That’s a record, marking the “highest-priced home resale in Chicago-area history,” according to the Chicago Tribune.

Listing agent Jena Radnay called it a “one-of-a-kind situation” and described the sale as “seamless from one generation into another.”

“Everything kind of fell into place for all the right reasons,” she told NBC Chicago.

The home was first listed in August 2024, described as “the most iconic lakefront estate in IL,” according to its listing.

“The ‘Windsor House’ has been elevated to a new grandeur of living with a best in class collaboration lead by nationally recognized interior design, landscape architects & coastal engineering teams,” the listing read. “Gloriously expanded to 2.3 acres with the purchase of 429 Sheridan transformed into a commercial level botanical garden with a Lannon stone custom fountain, manicured hedges & grassy lawn, heated motor court for 10 cars, & meticulously engineered nailess pergola overlooking the infinity pool area with panoramic lake views. The only home on the entire shoreline that is reminiscent of 5-star boutique level European hotel delivering a true vacation living experiences 365 days a year.”

The 22-room mansion was designed with French inspiration and includes 223 feet of private beachfront property that includes a boathouse and commercial-level boardwalk.

“There is nothing even remotely comparable to this estate,” the listing read.

Radnay said the year-long search for a buyer proved fruitful, but she wasn’t worried about the price.

“I really believed in the price because I knew the house delivered,” she said. “There’s always a buyer when something is truly unique.”

The home wasn’t the most expensive mansion to be listed in the Chicago area, however.

In 2022, a luxurious Lincoln Park estate was listed at a record $50 million – the most expensive home for sale in Chicago. The price later dropped to $45 million, and again to $30 million. It ultimately sold for $15.25 million.
