1100 Park Ave

1100 Park Avenue is an 18-story, prewar cooperative built in 1930 by De Pace & Juster, combining landmark-era architecture with full-service, white-glove living. The building contains fewer than 30 units, favoring large, multi-room residences—predominantly four-bedroom apartments and expansive duplex penthouses—many accessed via semi-private or private elevator landings. Interiors typically showcase classic prewar details: high ceilings often above ten feet, hardwood/herringbone floors, wood-burning fireplaces, ornamented moldings and generous galleries or entrance foyers. Units feature formal dining rooms, eat-in chef’s kitchens with pantry space, multiple walk-in closets and built-in millwork; select residences include private outdoor terraces and staff rooms. Common areas and services include a 24-hour doorman, live-in superintendent, newly updated fitness room, bicycle room and private storage bins that transfer with apartments. The cooperative is pet-friendly, allows pieds-a-térre in many cases, permits up to 50% financing in some units, and applies a 2% flip tax. Located on Park Avenue at East 89th Street in Carnegie Hill, the building sits two blocks from Central Park and Museum Mile, with convenient subway and bus access plus neighborhood shops, restaurants and cultural institutions nearby.
