Solow files plans for 19-story resi building next to 9 West

Graphic artist Ivan Chermayeff’s “Red 9” sculpture outside Sheldon Solow’s exclusive 9 West 57th Street office tower may be getting a neighbor.

Solow is planning to develop a 19-story, 16-unit residential next door to the iconic commercial tower at 7 West 57th Street, according to application filed with the city Department of Buildings Thursday.

Details are scant, but the developer plans to include 32,099 square feet of residential space and 4,131 square feet of retail space on the 32-foot-wide lot on the eastern side of 9 West, according to filings.

A representative for notoriously press-shy Solow was not immediately available for comment.

Solow bought the property, which is now home to a five-story brick building, for $25.5 million back in 2005.

While technically on Billionaires’ Row, the proposed building will top out at 237 feet tall, a fraction of the size of the supertall towers that have come to define the luxury residential enclave.

The architect of record is Hill West, which recently changed its name from Goldstein Hill & West after the named partner retired.

Solow last year paid $128 million to buy a development site on the opposite side of 57th Street, where he could build a tower with 213,000 square feet of residential space.
