This new, 10-story, 43,000-SF residential condominium is located in the Carnegie Hill Historic District in Manhattan. Located just a block from Central Park, this project consists of a buffed-colored brick and an articulated limestone base over a concrete superstructure main building containing seven full-floor apartments and one penthouse duplex unit. In order to erect the 10-story building above the bank, Pavarini McGovern constructed a steel platform above the existing one-story branch bank, which remained fully operational through construction. The project also included a 4-story townhouse located directly to the north of the main building, at 1281 Madison Avenue, which contains a ground-level commercial unit, four residential units for the residents' domestic support staff, and an apartment for the property's on-site superintendent. Many of the residential units were customized during construction to meet the needs of the future owners.

The structural engineer proposed a system comprised of a conventional reinforced concrete building supported on a structural steel transfer plate that would deliver building loads to a new residential core and just five other steel columns. Working closely with the architect and Citibank, the engineer chose column locations that would minimize disruption of bank operations because aside from 14 prearranged closure dates, the bank operated during its regular hours Monday through Saturday.

Over one weekend, the five steel columns - which would support about three quarters of the building's gravity load - were "needled" through holes in Citibank's roof and ground floor and placed upon concrete footings in the bank basement. Over two subsequent weekends, the steel transfer plate on the second floor was erected. Once completed, the steel transfer plate and existing bank roof provided enough protection so that construction could proceed without closing the bank.
