The owners of a gas station were able to reap the benefits of both the High Line and inclusionary air rights when it was sold for $23.5 million to become a condo.

Offers had been made to the owners of as much as a record $600 a foot when Brock Emmetsberger, first vice president of sales, and James Nelson, a partner at Massey Knakal, were retained to sell it.

“Because they already had record pricing on the table, we knew we could do better,” said Emmetsberger, who explained to the owners the “bottleneck” caused by too many buyers and too few sites along the High Line, especially those on avenues with corners for retail.

Because this was a receiving site in the Special West Chelsea District, as well as in the High Line Transfer Corridor, the brokers canvassed the neighborhood, and in some cases were exclusively retained, to sell more transferable and inclusionary air rights along with this sale.

“It was a way to create additional leverage to help get past the fact it was an operating gas station,” explained Nelson.

The sale to Michael Shvo, CEO of residential development company Shvo, who teamed up with Victor Homes, set a price-per-square-foot record for Chelsea at $23.5 million — or $855 per foot for 27,300 buildable square feet. This was over the asking price of $18.95 million.

The final price will rise once the developers pay for the additional air rights, which could bring the building to a total of 41,475 square feet. It will be designed for and marketed toward art collectors.
