535 Park Ave

Built in 1909 and rising 15 stories, this is a small, full-service prewar cooperative on Park Avenue characterized by classical proportions and restrained Beaux-Arts detailing. The roughly two-dozen residences are predominantly two- and three-bedroom layouts that preserve historic features: high ceilings (often around ten feet or more), crown and custom moldings, original or restored oak floors, large oversized windows and wood-burning fireplaces. Units commonly include formal galleries or entrance foyers, eat-in kitchens with high-end appliances, built-in cabinetry, walk-in closets and recessed lighting; many apartments also feature Juliet balconies, private outdoor spaces and windowed baths with stone finishes. The building’s exterior presents a red-brick façade with terra-cotta basework and wrought-iron balcony accents, and a canopied main entrance leading to an elegantly appointed lobby. Shared resources emphasize white-glove service rather than lifestyle programming: 24-hour doorman, live-in superintendent, several porters, dedicated private storage for shareholders and a secured common roof terrace. Operationally the co-op maintains modern infrastructure—recent roof, boiler and electrical upgrades—and governance permits pied-a-terres, pet ownership, trust purchases and up to 40% financing; a 2% flip tax is payable by purchasers. The address sits two blocks from Central Park at the intersection of shopping, cultural institutions and transit on the Upper East Side.
