20 Sutton Pl S

20 Sutton Place South is a post‑war cooperative completed in the mid‑1950s that rises 22 stories and contains fewer than 50 residences, giving it a low‑density, vertical townhouse feel. The red‑brick exterior presents a restrained midcentury profile; many apartments capture partial East River and Queensboro Bridge views. Residences are predominantly multi‑bedroom layouts — including classic “six” plans and expansive 2‑ and 4‑bedroom configurations — featuring formal entrance foyers, separate dining rooms, eat‑in and galley kitchens, ample closet and pantry storage, and period details such as crown moldings and hardwood floors in renovated and original finishes. Units vary widely from renovated architect‑owned loftlike schemes with open great rooms and high‑end appliances to intact traditional layouts with wood‑burning fireplaces and built‑in cabinetry. Common areas emphasize full‑service convenience and communal outdoor space: a staffed 24‑hour doorman, live‑in resident manager, concierge and a planted rooftop deck with sweeping city and river panoramas. Onsite support amenities include a fitness room, central laundry, individual storage cages and an in‑building garage (rarely available parking). Building policies favor cooperative governance — boards review pets, pied‑a‑terres and foreign buyers — and the property operates as a smoke‑free building with varied pet rules. Located between 55th and 56th Streets along the East River in Sutton Place, the address offers a quiet, residential streetscape with nearby grocery, dining, tennis clubs, riverside parkland and straightforward transit access to Midtown.
