823 Park Avenue is an exquisite luxury pre-war condominium built in 1912 by Pickering and Walker and extensively renovated around 2006. This intimate building has only 10 full-floor residences, a duplex penthouse, and a maisonette, each with its own private landing. Each spacious 4,100 sq ft home features two fireplaces—one in the library and one in the living room—offering a combined 45-foot view west over Park Avenue. Homes boast high ceilings, eat-in kitchens, and refined finishes throughout. The beige limestone exterior is designed in classic Greek Revival style, reflected in the elegant renovated lobby and sculpted window accents. Abundant windows provide stunning views of this historic neighborhood. Amenities include a fitness room and additional storage.
