Just off Fifth Avenue and moments from The Metropolitan Museum of Art and Central Park, 21 East 81st Street is a distinguished limestone townhouse on one of the Upper East Side's most beautiful blocks.

Designed in 1899, this 20-foot-wide residence spans approximately 8,600 square feet across six levels. The interiors are beautifully proportioned with impressive ceiling heights, original architectural details and multiple wood-burning fireplaces. An elevator services all levels.

The grand entertaining floor features soaring 12-foot ceilings and generous rooms filled with natural light. A substantial kitchen provides plenty of space for both everyday living and entertaining.

Above, a landscaped roof garden offers a private retreat with ample room for dining, lounging and entertaining.

The home is currently configured as an expansive owner's quadruplex with a separate income-producing duplex. The layout also works well for extended family, guests, staff or a private office. Alternatively, the townhouse can be returned to a grand single-family residence.

With its limestone facade, mansard roof and gracious scale, 21 East 81st Street offers the character of a classic New York townhouse with the space and flexibility for modern living in an extraordinary location.
