In a surprising decision a couple of weeks ago, a state judge ruled to revoke the approval for the top 20 floors of a market-rate, luxury, residential building on the Upper West Side, 200 Amsterdam Ave.

Despite the unusual zoning lot that the developers created to amass the air rights for this 52-story tower, few would have imagined that after receiving the required approval from the Department of Buildings and the Board of Standards and Appeals, the developer may need to demolish the upper third of the building.

Instead of wasting this already-built space, Esther Sperber proposes an alternate solution to convert the bottom 20 floors of the building into 160-200 new affordable housing units. This idea is more environmentally friendly than demolition and would improve the city’s socio-economic issues.
