An iconic New York ‘bubble house’ has gone on sale for $5.75m.
The four-bedroom property, built in the Lenox Hill neighbourhood by architect Maurice Medcalfe in 1969, has not been on the market in decades.
It earned its nickname after it was transformed from a traditional brownstone into an eye-popping modernist masterpiece, as reported by Luxury Property News.

Medcalfe’s distinctive window design – which sees curved glass ‘popping’ out of its frame – was an artistic take on the classic bay window.

He also made it so that some of the windows could be unlocked and spun around to let fresh air in.
Following the remodel, the townhouse was quickly sold and has remained in the same private ownership for the past 50 years.
The home includes five bathrooms and an office on the garden level, which could function as an additional bedroom.

Along with its four upper stories, the residence features an 800-square-foot basement.
While the striking façade hints at a futuristic aesthetic, the minimalist, white-walled interiors are far more restrained.
Notable features include several fireplaces and a walled rear garden shaded by mature trees.

The listing reads: “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.”
The house is for sale with Richard Pretsfelder from Leslie Garfield for $5,750,000.
