Description

Elegant and fully renovated townhouse, built in 1910 and situated just off Fifth Avenue in the Upper East Side's most coveted residential enclave. Spanning five principal floors, the 13-room home offers six bedrooms, four full baths and one powder room. There are high ceilings throughout with sunlight streaming into the rooms through tall handsome windows. There are multiple fireplaces for the cold winters and three private terraces for the lovely warm weather months, as well as a ground floor garden with fountain. On the garden level, two separate entrances provide the convenience of a formal entrance opening to a gracious gallery, and a second entrance that leads to a dedicated mudroom area perfect for everyday use or inclement weather. This floor also features a renovated, generously proportioned kitchen with large dining area, gas fireplace and state-of-the-art appliances. Oversized glass doors lead seamlessly to the private garden and fountain. The parlor floor offers grand entertaining rooms, including an expansive living room with a wood-burning fireplace, 12-foot ceilings, custom moldings as well as a formal dining room with a gas fireplace, comfortable for many. French doors from the dining room open onto one of the home's three private terraces. A thoughtfully designed butler's pantry adjoins the dining room. The third floor is devoted to the serene primary suite, with a generously proportioned bedroom and a decorative fireplace overlooking tree-lined southern views, along with a newly renovated bath and dressing area. There is also a library/sitting room with gas fireplace which has access to an additional outdoor terrace. The fourth floor offers two additional large bedrooms and access to another private terrace along with a full bath. The fifth floor provides three further bedrooms and two full baths, along with a kitchenette offering exceptional flexibility for family, guests, or staff. The full basement provides abundant storage and houses the laundry room and mechanical systems. Throughout, original prewar architectural details, including soaring ceilings, custom moldings, and several fireplaces, are complemented by sophisticated renovations and modern technology. The result is a rare combination of historic character, contemporary comfort, and exceptional privacy. Parkside and exceptionally well located, 9 East 77th Street offers the rare opportunity to live in a private townhouse setting while enjoying immediate access to Central Park, Fifth Avenue, world-class shopping, dining, museums, and all that the Upper East Side has to offer.
