Description

Designed by renowned architects Harde & Short in 1906 and classified as a landmark in 1977, 45 East 66th Street is distinctive for its magnificent gothic-inspired terra cotta and brick façade. Within a “monumentally exuberant” edifice, this splendid residence boasts bright, high-floor outlooks and an abundance of sunshine, high ceilings, and beautiful hardwood floors. Further, the thoughtful and inviting layout of the apartment is complemented by copious original detail, such as wood paneling, and leaded-glass and 12-over-12 paned double-hung windows. Accessed by a semi-private elevator landing, the welcoming, square Gallery opens into the Living Room, which benefits from pleasing proportions and three very large west-facing windows. Adjacent, a handsome wood-paneled corner Library with a wood-burning fireplace offers open views up Madison Avenue and to the west. Nearby, a stately, well-proportioned Dining Room is oak-paneled and boasts a carved plaster ceiling and very tall leaded glass windows. The Dining Room is further distinguished by its Conservatory. With impressive leaded glass eastern and northern-facing windows, it is marvelously light-filled and ideal for a tranquil breakfast or cozy dinner. Beyond, the cheerful eat-in-Kitchen with northern and eastern exposures and open outlooks is supported by a proper Butler’s Pantry, a Laundry Room, and a Staff Room with an ensuite bath. Tranquil private quarters are separated from the entertainment rooms by a long hallway. A massive Primary Bedroom, originally two bedrooms, has open western vistas and ample space for seating. Its very large ensuite windowed bathroom, also originally two bathrooms, is well appointed with a large soaking tub and a separate full-size shower. There are two additional Bedrooms and a shared bathroom. Impeccable staffing at this white glove cooperative includes a 24-hour doorman, porters, and a resident manager. Ideally situated, 45 East 66th Street is moments from Central Park and convenient to Madison Avenue’s shops and restaurants, as well as to many of the Upper East Side’s best schools, museums, and galleries. The building has no summer work rules and permits financing up to 50%. Pets are welcome. Please note that some images have been digitally staged.
