721 5th Ave

A 58-story, 1983-built condominium tower on Fifth Avenue, this high-rise contains 72 large residences ranging from one- to three-bedroom layouts. The building’s exterior is a glossy, black-glass modernist tower that presents expansive city and park panoramas from high floors. Interiors commonly feature formal entry foyers, separate dining rooms, plaster and parquet finishes, generous walk-in closets and windowed marble baths; many homes offer floor-to-ceiling glazing and oversized corner rooms. Shared spaces include a staffed white-glove lobby with attended elevators, a private 56th Street entrance for residents, and a landscaped courtyard. A comprehensive amenity floor introduced in recent years adds an expansive fitness center and yoga studio, a screening theater, library and business center, a residents’ lounge and event spaces, children’s playroom and billiards room. Services extend to 24-hour doormen and concierge, valet, laundry and housekeeping options. Parking is handled via valet arrangements and nearby garages rather than large on-site lots. The building generally enforces a no-pets policy and accommodates primary residences, pieds-à-terre and investor ownership. Located at the crossroads of Fifth Avenue, adjacent to flagship shopping, luxury hotels, fine dining and Central Park, the tower sits in a high-fashion, highly walkable Midtown neighborhood with easy transit connections.
