La Gorce Palace's penthouses have found themselves in a unique position, as they are listed separately for a combined $5.9 million, but the seller has made it known that a buyer can have them both for $5 million. Currently the units are connected via a rooftop terrace, but the buyer will have the option to knock-down the walls to create a mansion high-in-the-sky. Penthouse 1-2, already a combined duplex, is 3,825 SF and asking $3,695,000. Next door, Penthouse 3 is asking $2.25 million for its 2,280 SF. The rooftop terrace is over 3,100 SF. The price comes to roughly $650 SF including half of the outdoor space in the number. Listing and photos by Justin Rubin of The Rubin Group, Douglas Elliman Real Estate.
