1160 3Rd Ave

The Frost House is a 19-story cooperative building completed in 1965 on Manhattan’s Upper East Side, offering 85 residences that range from studios to one- and two-bedroom apartments. Architecturally modest and mid-century in origin, the property presents a renovated lobby and a traditional elevator-served layout with multiple penthouse duplexes and units that emphasize high ceilings and large windows. Interiors commonly feature period and upgraded details such as hardwood floors, crown molding, built-in bookcases, granite or quartz counters, eat-in and galley kitchens, generous closet systems including walk-ins and his-and-hers configurations, and occasional chandeliers and formal entry foyers. Many units include private outdoor space — balconies or planted terraces with utilities for irrigation and exterior power — and some upper-level residences showcase floor-to-ceiling glazing and duplex arrangements. Building services and shared spaces include a 24-hour doorman, live-in superintendent, central laundry room, bicycle storage, and a bike room; on-site management handles routine maintenance and recent capital improvements have addressed electrical and HVAC systems. The coop permits sublets, pied-à-terre ownership, co-purchasing and certain ownership structures with board approval; the pet policy is restrictive (cats typically allowed; dogs often prohibited). Located on Third Avenue between East 67th and 68th Streets in Lenox Hill, the Frost House sits steps from multiple subway lines, Central Park, grocery and retail options, and neighborhood dining, positioning it as a full-service option for residents who want reliable building staff and outdoor terraces in a dense, well-connected residential enclave.
