Offered for the first time in decades, 251 East 71st Street is a one-of-a-kind townhouse that combines historic New York roots with a bold mid-century architectural statement.

Originally constructed as a traditional brownstone in the 19th century, the building underwent a visionary redesign in 1969 by architect Maurice Medcalfe of Hills & Medcalfe. Medcalfe transformed the façade into a modernist icon with its smooth stucco exterior and signature convex oval windows — a sculptural interpretation of the classic bay window that floods the interiors with natural light while offering a striking presence on the block.

Inside, the home offers approximately 4,736 square feet across four stories plus a basement, currently configured with 4 bedrooms, an office, and 5 bathrooms, all in need of renovation. An office occupies the garden level, providing flexibility for live/work use, while the upper floors feature generously proportioned rooms ready to be reimagined for modern living.

The home sits on a quiet, tree-lined block in Lenox Hill — moments from Central Park, acclaimed restaurants, boutiques, and convenient transit. A rare opportunity to own an iconic piece of New York City architecture, 251 East 71st Street stands out as a testament to originality and craftsmanship, ideal for a discerning buyer who values history, design, and individuality.
