Lake Geneva’s Historic Waterfront Allegheny Estate Hits Market

A nearly 21-acre waterfront estate in Lake Geneva hit the market Thursday for $24 million, claiming the title of southern Wisconsin’s most expensive active listing.

The property, known as Allegheny, features a 102-year-old Colonial-style mansion and 560 feet of Geneva Lake shoreline on South Lake Shore Drive. The $24 million ask is more than double the price of the market’s previous top listing, a 9.2-acre estate at W2908 Walcowis Drive that hit the market last week for nearly $11 million.

David Curry of Geneva Lakefront Realty holds the Allegheny listing. Curry declined to comment on the property, but in an interview earlier this month with The Real Deal he highlighted the lack of inventory in the area’s ultra-luxury sector, noting he could sell multiple $15 million to $25 million properties within 30 days if they were available. The competing Walcowis Drive property, listed by Tricia Forbeck of Compass, features 160 feet of shoreline and a five-bedroom main home.

A sale near Allegheny’s asking price would mark the fourth Lake Geneva-area property to trade for $20 million or more. The area’s last transaction in this tier was an off-market $20 million sale on Lackey Lane in June 2025. The largest residential sale on the lake so far this year was the $14.3 million off-market trade of Sprout Social founder Aaron Rankin’s Fontana mansion in March.

Completed in 1925, Allegheny was the final Lake Geneva project by Chicago-based architect Howard Van Doren Shaw. The estate features a wishbone entry off South Lakeshore Drive that routes vehicles through a carriage house and an old-growth forest. The main residence retains its original hardwood floors, five masonry fireplaces and century-old wallpaper by Parisian artisan Zuber.

The estate’s acreage sits under a conservation easement, prohibiting subdivision for new home development.

Shaw designed the home for Lewis Myers, an industrialist who worked for Thomas Edison before making his fortune in the late 1800s electrifying Chicago’s elevated trains and city streetlights. The Styberg family purchased the property in 1945 following Myers’ death. A trust in the name of the late Bernice Styberg currently owns the estate. Her father-in-law, Ernest Styberg, headed a Racine, Wisconsin-based firm that manufactured military, bicycle and telephone components.

Previous Shaw-designed properties in the area command top-tier pricing; Aloha Lodge sold for nearly $22 million in 2024, and Villa Hortensia sold for $17 million in 2022 before being demolished to clear the site for new homes.
