420 E 55Th St

Sutton Gardens is a mid-century, red-brick cooperative built in 1956 and rising 12 stories with 54 residences. The stock includes studios, one- and two-bedrooms, junior-four conversions and occasional three-bed combinations formed by joining units. Typical residences show mid-century bones—high ceilings, parquet or wide-plank hardwood floors, crown molding and built-in millwork—alongside updated kitchens and renovated baths in many apartments. The property is arranged as two wings around a landscaped, planted courtyard and garden, with north and south elevator banks serving residents. Building services are full-service: 24-hour doorman/concierge, live-in superintendent and on-site garage. Common conveniences include two laundry rooms, bicycle storage, additional resident storage rooms and planned lobby improvements. Many apartments have private outdoor space—balconies or small terraces—and some units look toward the East River. The co-op board is permissive on financing and use, routinely allowing 80% financing, pied-a-terres, co-purchasers, guarantors and, with approval, sublets; pets are permitted. Located on a quiet, tree-lined stretch of East 55th Street in Sutton Place, the building sits steps from Sutton Place Park, the East River esplanade and neighborhood dining, grocery options and transit connections that blend Midtown convenience with a riverfront residential character.
