This massive Lake Michigan-front mansion asks $35M — the most expensive home for sale in its state

An historic 20,000-square-foot estate in the tony Chicago suburb of Winnetka has listed with an asking price of $35 million, making it the most expensive property for sale in Illinois.

Built in the 1920s, the century-old stunner is being sold by its longtime owners — current financier and former Goldman Sachs global co-head of the principal debt group Muneer Satter and his wife, Kristen Hertel — who purchased it for $9.5 million 2002, the Wall Street Journal reported . A huge selling point: a prime waterfront perch.

“This is an iconic lakefront property in the north shore” of Lake Michigan, Jena Radnay of @properties Christie’s International Real Estate, who holds the listing, told The Post of the “spectacular” compound.

Other fittings include 223 feet of sandy beach; a commercial-level boardwalk that wraps the lakefront; and a “double-door, state-of-the-art boathouse with ‘in bluff’ his-and-her changing rooms and a hotel-level edgeless pool and spa,” Radnay added.

During their 22 years of ownership, Satter and Hertel extensively renovated the French Normandy-style residence, reportedly sinking approximately $35 million into its restoration and expansion to its current 2.3 acres. The couple, Radnay told the outlet, are selling as they downsize; most of their five daughters having now grown up and moved out.

The limestone abode was originally constructed for Popular Mechanics publisher Henry Haven Windsor Jr., who occupied the property with his opera singer wife, Louise Hunter.

A number of period details remain from Windsor’s time there, including the home’s original stained-glass windows, parquet floors, a few decorated ceilings and the dining room’s mahogany paneling.

Today, the compound is listed as having seven bedrooms and plenty of other inclusions. Those are a wine cellar, multiple offices, libraries, a tropical-mural decorated Palm Room — and, on the grounds, manicured hedges, botanical gardens, a heated motor court for 10 cars and a custom Lannon stone fountain.
