Jessor became known for ensuring working-class families had proper social amenities in their daily lives. He included entrance
foyers, eat-in kitchens with windows, and bedrooms with cross-ventilation, so working-class families without
air-conditioning could benefit from natural breezes. At the time Jessor was an architect, air-conditioning was especially expensive. He eschewed the typical
railroad flat design, which required walking through one room to get to the next, favoring a design where rooms were accessed from a common hallway, providing more privacy to the residents. Jessor was a close ally of such
labor unions as the
Amalgamated Clothing Workers Union, the
International Ladies Garment Workers Union, and the
International Brotherhood of Electrical Workers. Many of the buildings he worked on were funded with the help of these unions. In January 1999, in the wake of a collapse in the
Seward Park Housing parking garage, New York City building inspectors suspected there could be a potential flaw in Jessor's "honeycomb" design of the massive garage roof. The roof had been built to support a vast playground/park above, with trees and grass upon hundreds of thousands of pounds of soil. After the collapse on Friday night, January 15, 1999, the
New York City Department of Buildings opened an investigation into other Jessor projects to test for durability. The investigation did not turn up any major design flaws, and cited convergence of many elements including several days of warm rain, followed by quick freezing, thawing, and refreezing, along with a stoppage in the drainage system combined with minor cracking of the concrete in the roof and the immense weight above. After a four-year lawsuit, the Greater New York Insurance Company, insurer for Seward Park Housing, lost their nonpayment case to the cooperative, and $18 million for the damages. After the insurer won a subsequent appeal, the insurer and coop settled in 2010 with the coop returning $3.25 million to the insurer. ==See also==
