Oheka Castle to auction in New York with developable condo site

Oheka Castle, the 127-room Long Island landmark featured in Citizen Kane and Taylor Swift's Blank Space, is headed to auction through Concierge Auctions. The sale includes a 5.13-acre developable site approved for 95 luxury condominiums, adding a rare development angle to one of America’s most famous private estates.

Why it matters: - Oheka Castle is one of the most recognizable private estates in the U.S., with cultural cachet, wedding revenue and development potential in one offering. - The auction could reset expectations for trophy real estate near Manhattan, where large-scale, historic estates rarely come to market. - The adjacent entitled land adds a second value story beyond the mansion itself.

What happened: - Concierge Auctions will sell Oheka Castle in cooperation with Adam Modlin of The Modlin Group. - Bidding is scheduled to open and culminate live on 27 October at The Dominick in New York City. - The property sits on Long Island's Gold Coast, about 40 miles from Midtown Manhattan. - The estate is a 127-room French Renaissance château and a National Register landmark. - Oheka Castle is described as the second-largest private residence ever built in America.

Between the lines: - The listing pairs prestige with optionality, giving bidders a historic residence, an established hospitality business and a separate development play. - Concierge Auctions is using the property’s fame and scarcity to reach buyers who want a landmark with income and repositioning potential. - The long list of film and TV credits reinforces Oheka Castle's role as both a real estate asset and a pop culture brand.

What's next: - Bidders will compete at the live auction in New York on 27 October. - The closing will trigger a donation through Concierge Auctions' Key For Key program. - The next owner will inherit both the restored estate and the approved development opportunity.
