feature School Back in Session after 30-Year Recess The historic but dilapidated P.S. 90 provided a perfect opportunity for adaptive reuse. Now condos and choreography do a pas de deux BY CLAIRE WILSON hen Mark Ginsberg, FAIA, LEED AP, first laid eyes on P.S. 90, the roof was gone. There were no windows. Trees sprouted from the top of the building, which had been abandoned in the 1970s, a casualty of the city’s fiscal crisis. Derelict apartment buildings lined the street. No one walking that block of West 148th Street in Manhattan today would find evidence of that dreary chapter now. P.S. 90 is a stellar 1907 example of Collegiate Gothic architecture designed by Charles B.J. Snyder, the superintendent and chief architect for NYC schools from 1891 to 1922. Ginsberg’s firm, Curtis + Ginsberg Architects, tucked 75 bright, spacious new condo units into the old school. What was once the school’s basement and auditorium is now home to the National Dance Institute (NDI), a nonprofit dance education program founded in 1976 by Jacques d’ Amboise, former principal dancer with the New York City Ballet. All the older, low-rise residential dwellings along the street have been refurbished, most by L+M Development Partners, the developer of the PS90 Condominiums. Ginsberg recalls what a mess the school was at the outset, covered with mold and still filled with desks, chairs, and school paraphernalia. It was also dangerous. “If you stepped in the wrong place you’d go right through the slab,” says Ginsberg. Replacing those slabs on all five floors was the first order of business. Next was designing a layout using the original window configuration of the throughblock “H” plan inspired by Paris’s Hotel de Cluny. The architect then devised attractive, double-hung, operable windows with a third, fixed pane at the top. The exterior frames are painted to match the decorative details on the building’s façade. For the lobby, Ginsberg dropped the ground floor to create a double-height space that also provides elevators between the lobby and all floors. “Coming in on the ground level to a double-height lobby created a much more gracious entrance,” Ginsberg says. An elegant new staircase leads up to the first floor, which opens onto a common garden court yard, designed by Curtis + Ginsberg Architects Thomas H.

The sunken, landscaped entryway at the front has the pleasant feel of a garden oasis slightly below street level. Twenty of the 75 units are affordable housing and, except for finishes, identical to the market-rate condos. The dance institute will use residential units as offices (d’ Amboise will also be a tenant), and the lower level for studios and a performance space. “There is a beautiful synergy with the fact that it is a revitalized public school and we are a public-schoolbased program,” says Kathy Landau, executive director of NDI, which teaches 4,000 students citywide. PS90 incorporates a number of sustainable features: insulated low-E glass windows; Energy Star appliances; energy-efficient heat pumps, boilers, and light fixtures; light-colored paving materials on the rooftop and courtyards; and drought-resistant plantings. Most importantly, adaptive reuse preserved the existing building’s embodied energy and its incalculable beauty. It was a long, hard project, says Ginsberg, but restoring “this wonderful, historic building” was well worth it. ■ Claire Wilson writes for the New York Times.
