The residential conversion of the very impressive former warehouse building at 415 Greenwich Street will have not one atrium but three, two of which will be designed by Thomas Balsey, the landscape architect whose projects include Riverside Park South and the atrium at Trump Tower.

The free-standing building, which is notable for its very fine and large cornice, will have 66 condominium apartments. Two setback penthouse floors were added to the former 8-story building, which is within a landmark district.

It has a prime TriBeCa location and is located between Hubert, Collister and Laight Streets and is catty-corner to the large and impressive office complex at 388 Greenwich Street.

Some units will be known as bay apartments because they were have sidewalk terraces with six-step-up entrances and a glass canopy over the terraces, which are modern interpretations of the traditional truck loading bays of older commercial properties.

Many of the apartments have unusual layouts.

Loft 2C, for example, has a 37-foot-1-inch-by-6-foot entrance gallery that leads into an open kitchen area that measures 16-feet-11-inches-by14-feet-nine-inches that opens onto a living space that measures 34-feet-2-inches-by-15-feet-inches.

Loft G on floors three through eight has a 48-foot-by-7-foot entrance gallery that leads to a 29-foot-by-15-foot-1-inch living space. Its kitchen and dining/family space open onto a balcony about 21 feet long overlooking the large "south" atrium.

Occupancy is expected in about a year.

The building will have a concierge, a garage, a landscaped sundeck, a fitness center, and a children's play area.

The handsome building was designed by Victor A. Bark and completed in 1913 as a neo-Renaissance style warehouse.

The building was sold by the Globix Corporation in January, 2004 to 415 Greenwich Fee Owner, LLC, a successor in interest to Heritage Partners, for $60 million in cash.
