420 E 64Th St

A 12-story, 66-unit midcentury condominium/co-op hybrid built in 1955 on Manhattan’s Upper East Side. The masonry-faced structure contains primarily one- and two-bedroom residences, many reconfigured over time to include dens, windowed kitchens, and formal entry foyers. Interiors commonly feature hardwood floors, generous closets, eat-in or galley kitchens, and a mix of original and renovated finishes; several units showcase oversized windows and exposures to a landscaped internal courtyard. Shared spaces are extensive for a building of this scale: a staffed 24-hour doorman/concierge desk, a live-in resident manager, passenger elevators, laundry room, and dedicated storage and bike rooms. The property sits around a half-acre of professionally landscaped gardens and a covered courtyard offering substantial private outdoor space and terrace opportunities for penthouse units. Building services include a fitness room, package/storage provisions, and an on-site garage available to residents for an additional fee. The house rules are liberal: condop governance permits co-purchasing, parental purchases, gifting, immediate subletting, and generally investor-friendly policies. Pets are allowed and the board operates with condominium-style rights including a right of first refusal. Located within easy walking distance of multiple subway lines, restaurants, grocery stores, medical centers, and the East River Esplanade, the building blends full-service urban conveniences with leafy, garden-facing calm.
