A 13-story prewar cooperative completed in 1936, this mid-rise masonry building reflects Emery Roth–era design within a small, 39-unit ensemble. Units are predominantly two-bedroom layouts that retain classic details such as high beamed ceilings, original hardwood floors, built-in cabinetry, generous foyers, and wood-burning fireplaces in select residences. Apartment interiors commonly feature separate formal dining areas, galley or eat-in kitchens with windowed exposures, multiple walk-in closets, storage rooms, and some residences include private planted terraces or roof-deck access. The building’s shared spaces emphasize a gracious, residential scale: an attended lobby with full-time doorman, a live-in resident manager, on-site management office, laundry facilities, bike room, and on-site storage. Outdoor amenities include a landscaped private garden, planted courtyard, and a communal roof deck; several units advertise private outdoor spaces ranging from compact balconies to nearly 700 square feet of planted terrace. Services and policies favor flexibility—pied-à-terre ownership, pets, and competitive financing are permitted with board approval—while maintenance commonly covers electricity. Located on a quiet, tree-lined block in the Beekman Place/Southgate enclave near the East River promenade and local parks, the building blends prewar architectural character with full-service conveniences and a residential, neighborhood-oriented lifestyle.
