Marketing has begun for the "Zinc Building" at 475 Greenwich Street in TriBeCa.

The building, which is triangular in plan, is being developed by Douglaston Development of which Jeffrey E. Levine is a principal.

The building will contain 21 condominium apartments and is located on a triangular block bounded by Canal and Watts Streets. The site is over the Holland Tunnel and has been occupied by low-rise buildings that once housed a ceramic tile company and a car audio store.

The developer obtained a zoning variance last year for the 7-story project and has agreed with Community Board 1 not to lease any of its retail space to nightclubs, or bars.

A sales office is expected to open at 145 Hudson Street next month.

A new rendering of the building by Greenberg Farrow Architects indicates that the project has been redesigned and the new design has a setback-top floor with an overhang but not any slightly angled windows.

Mr. Levine told CityRealty.com today that the project is now in foundation work and should be completed in about 16 months.

He said that apartments will range in size from about 1,000 square feet for one-bedroom units to about 2,400 square feet for four-bedroom apartments. He said the duplex penthouse units will have wrap-around terraces.

The builidng, which is located near several other new residential construction projects in north TriBeCa and southwestern SoHo, will have a 24-hour attended lobby, refrigerated storage, individual storage units, a superintendent, floor-to-ceiling windows with operable center sashes, 10- to 11-foot-high ceilings, Asko washers and dryers, Sub-Zero refrigerators, Miele gas cooktaops and dishwashers, Franke sinks, white oak Italian kithcen cabinetry with frosted glass upper cabinets and under-cabinet lighting, Kohler 6-foot whirlpool baths, frameless glass showers with Grohe rainshower heads and Thassos white marble slab bathroom countertops and dual sink vanities.

Douglaston Development is nearing completion of a condominium apartment tower at 325 Fifth Avenue.
