Bidding opens at $6 million for a hidden Hampshire House penthouse

Concierge Auctions has opened bidding at $6 million for a three-level penthouse atop Manhattan’s Hampshire House, with the sale set to close July 14 through its online marketplace. The nearly 9,000-square-foot Central Park South residence comes with approved plans and permits, positioning it as a rare redevelopment opportunity in one of New York City’s most coveted addresses.

Why it matters: - The penthouse offers a chance to buy and reshape a trophy residence in a location where comparable opportunities rarely come to market. - The property sits atop one of Manhattan’s most recognizable buildings, directly overlooking Central Park and near Billionaires Row. - The sale could appeal to luxury buyers seeking both architectural history and a custom build path with plans already in hand.

What happened: - Concierge Auctions said the reserve has been met and bidding is open at $6 million for the three-level penthouse at 150 Central Park South. - The offering is being sold through Concierge Auctions’ Developer Services division in cooperation with Tal Reznick of Nest Seekers International. - Bidding will conclude July 14 on Concierge Auctions’ online marketplace. - The property was originally listed for $18.75 million.

The details: - The penthouse sits 37 floors above Central Park South and is hidden within Hampshire House’s copper roofline. - The residence spans about 9,000 square feet of total work scope across three levels. - The offering includes about 1,200 square feet of exterior living space, including terraces overlooking Central Park. - Buyers receive a package of previously approved plans and permits, subject to any required renewals or approvals by the building and relevant authorities. - SPAN Architecture created award-winning plans for the property. - Hampshire House dates to the 1930s and remains a white-glove cooperative known for privacy and exclusivity. - The building is steps from Central Park, Columbus Circle, Fifth Avenue shopping, and major dining and cultural destinations. - Images of the property are available at property photos and details. - Concierge Auctions said more information, diligence documents, and property details are available at ConciergeAuctions.com or by calling +1.212.202.2940.

Between the lines: - The auction format signals a push to create urgency around a highly specialized asset that may be difficult to price through a traditional listing process. - The approved plans lower one major barrier for a buyer, since the next owner can move faster on redevelopment than with a raw shell space. - The penthouse’s hidden placement inside a familiar skyline landmark adds a rarity premium that is as much about story and status as square footage.

What's next: - Bidding continues until July 14, when the property is expected to sell through Concierge Auctions’ timed process. - The closing will trigger funding for new homes through Concierge Auctions’ Key For Key giving program with Giveback Homes. - Agents are to be compensated under the terms of the listing agreement.
