voids

The Board of Standards and Appeals' vote resulted in a tie, which favors the developer.

According to an engineering analysis commissioned by Landmark West, less than 22 percent of the void designed for the condo project 50 West 66th Street is actually occupied by mechanical equipment.

Back in January, the design of the 775-foot-tall tower known as 50 West 66th Street appeared to be in jeopardy after the city's Department of Buildings threatened to revoke the project's permit.

A proposed zoning amendment is intended to discourage developers from using mechanical spaces, also known as 'voids' to add extra height to buildings.
