Eichner proposed CitySpire in 1984, acquiring unused air rights above City Center and making improvements to the theater to almost double the tower's area. After several agencies approved the project, City Center began construction in 1985 and was topped out by June 1987. A controversy ensued when the building exceeded its approved height by 11 or 14 feet (3.4 or 4.3 m); Eichner agreed to add dance-studio space to compensate for the height overrun, but he ultimately never built the space.
