610 Park Ave

Completed in 1925 and originally conceived by architect J.E.R. Carpenter as the Mayfair Hotel, this 15-story prewar condominium was converted to residence use in the late 1990s and contains roughly 67–70 apartments. The limestone-and-brick façade, high ceilings and classic proportions reflect traditional Upper East Side apartment-house design; many homes preserve plaster details, crown moldings and wood-paneled millwork alongside restored period doors and hardwood floors. Apartment types range from studios to large multi-bedroom layouts, several with formal dining rooms, foyers, libraries or maid’s rooms, and some corner residences offer three exposures and extended Park Avenue or city views. Interiors commonly feature eat-in or windowed kitchens, generous closet and built-in storage, separate service corridors in larger units, and in-unit washers/dryers in renovated residences. As a white-glove condominium, the building provides full-service staffing: 24-hour doorman and concierge, a resident manager, valet and housekeeping options, on-site fitness facilities and private storage. The ground floor includes the Michelin-recognized restaurant Daniel with private access for residents and available butler/room service; building services have included valet parking and maid services. Pet policies are resident-friendly with small-dog allowances. The location—Park Avenue at the mid-60s—places residents two blocks from Central Park, moments from Madison Avenue shopping, cultural institutions and well-served transit lines, offering a refined, service-oriented urban lifestyle rooted in classic prewar architecture.
