Janus Property Co., one of the most prolific developers in Harlem, filed plans this week for a new 428,000-square-foot commercial building on the site of a two-story storage warehouse in the neighborhood.

The new 12-story building at 460 West 128th Street, located between Convent and Amsterdam avenues, will hold a mixture of retail and office space as well as a medical facility, according to a permit application filed Tuesday with the city’s Department of Buildings.

Retail space will occupy the building’s ground floor, while the cellar and lower levels will hold offices and “multipurpose urban outdoor recreation [area] with eating and drinking,” according to the filing.

“Outpatient medical offices” will span the second through fifth floors of the property, while the sixth through 12th floors are designated for general offices. The top four stories at the property – floors 9 through 12 – will feature roof terrace spaces for tenants.

In total, the building will hold more than 107,000 square feet of “community facility” space for medical offices and nearly 322,000 square feet of commercial space.

Demolition permits for the existing warehouse on the site were approved in September. Janus Property Co., led by Scott Metzner and Jerry Salama, purchased the property – as well as two adjacent properties at 439 West 127th Street and 461 West 126th Street – for $5.5 million about a decade ago.

Neither Janus Property nor HOK, the project’s architect of record, could be immediately reached for comment.
