The Cornwall, built by Neville & Bagge in 1910, is a 12-story Upper West Side gem with a red-brick façade, limestone base, decorative balconies, and an Art Nouveau roofline. It has 38 apartments—mostly 2-4 bedrooms—with classic pre-war details like high ceilings, pocket French doors, and onyx fireplaces. This doorman co-op offers a restored lobby, rooftop terrace with city and river views, live-in super, and bike room. Pets are welcome. Located just steps from Riverside Park, it’s close to top shops, restaurants, and transportation.
