In May 1984, Eichner announced that he would build a 72-story skyscraper on the site, designed by Murphy/Jahn.[1] The building would contain 22 stories of offices and 49 stories of condominiums.[7][2] It would be shaped like an octagon with setbacks and a domed roof.[59] A key part of Eichner's development was his proposal to purchase unused air rights above City Center.[7][60] Eichner would also make improvements to City Center to obtain additional space.[7][31] The sale was expected to raise $10 to 14 million for the New York City Opera, New York City Ballet, and City Center's sublessee 55th Street Dance Theater.[5][59] The proposed air-rights sale received criticism both for its relatively low price[61] and for the fact that it would allow an excessively large building.[62] City Center Tower was one of several high-rise developments planned for the area at the time; Metropolitan Tower and Carnegie Hall Tower were being proposed as well.[63][64]
