Steeply Priced Roof Space Slashed

Steeply-pitched, unused mansard roof space in Manhattan heads to a slashed no reserve auction after failing to sell for £30.3 million

A currently unused roof space with an existing apartment overlooking Central Park that has bopped on and off the market since 2013 is being placed in a no reserve online auction early next month. It follows on from the fire sale of another ritzy penthouse we featured in June this year that went on the market for 64% lower than it sold for in 2014.


Featuring the existing 37th floor unit and having “pre-approved, shovel ready design, plans and permits” to extend into what was home to the mechanical systems of Hampshire House (alternatively known as ‘150 Central Park South), the potential triplex penthouse on offer could extend to 9,650 square foot.


Offered initially in 2013 for £12.7 million, the development opportunity was bought by a London based Israeli developer and artist named Arnon Katz in 2014 and 2015 for a combined total said to be £16.6 million. He attempted to sell it on for £18.9 million in June 2018 and then increased the ask to a staggering £30.3 million more recently.


Speaking of the 5-bedroom, 5.5-bathroom scheme – which also includes a “grand salon, formal living and dining rooms and an eat-in kitchen” – Katz remarked:


“Years of passion and knowledge went into the planning, design, and obtaining of the permits necessary to offer this extraordinary offering.”


“There is absolutely nothing else like it in the world, and this is what makes it truly special. I’m confident that Concierge Auctions’ incredible global reach and a team of top talent will identify the perfect buyer, an individual as unique as this property itself, who not only understands the value, but who also has the vision to complete this magnificent penthouse to its reality.”


The Concierge Auctions online sale commences on 18th December and closes on 22nd December and if sold, the buyer will get to live in a building dating to 1931 which has counted the artist Frida Kahlo and the tenor Luciano Pavarotti amongst its former occupants.

  1. It’s not a family home, is it? Most peculiar design. Interesting to find out who buys – maybe UHNW oligarch who desperately needs a 5th home.
