Built in 1940 by architect George F. Pelham Jr., 1150 Park Avenue features a modest Moderne design with red brick, vertical symmetry, and a granite base. The first floor showcases white limestone, and two red brick towers rise above the entrance. This 18-story Carnegie Hill co-op originally had 89 units, some now combined. Terraces are located on the 10th, 14th, 17th, and 19th floors. Converted to co-op in 1972, it offers full-service amenities including a gym, laundry, bike room, and resident superintendent. Storage may have a waitlist. Pets allowed case by case. Close to Madison Avenue, Central Park, the 92nd Street Y, and top schools.
