A restored Gilded Age mansion just off Fifth Avenue is listed at $68 million. While many of New York’s Gilded Age houses were demolished or converted, this one remains an intact single-family residence.

In the 1980s, when Nasser Nakib was a junior architect working in Soho, he used to slip over to Bond Street on his lunch breaks just to stand on the cobblestones. “In Provence you’re in a lavender field and you think, I could die happy here,” he says. “In New York, this block is it for me.”

A seven-story Beaux-Arts mansion — once home to a Russian prince and later restored from a shell — has come to market at $29.75 million.

Built for George Crocker, son of railroad magnate Charles Crocker, the 58-room Jacobean-style mansion was modeled after Bramshill House, one of the largest and most important Jacobean prodigy house mansions in England.

Nestled atop the historic Sohmer Piano Building in Manhattan’s Flatiron District, the sale of this opulent property will directly support the restoration of Mozambique’s Gorongosa National Park.

Located between Fifth and Madison Avenues, this landmark residence is steps from Central Park, world-class museums, and luxury shopping on Madison Avenue.

The grand, Gilded Age mansion was built in the Parisian Beaux Arts-style between 1901 and 1903 for prominent New York socialites, James and Harriet Lanier.

This timeless New York townhouse is nestled on a tree-lined street just a block from Riverside Park, surrounded by all the best of the Upper West Side’s neighborhood amenities.

Originally built in Amsterdam in the 17th century, the property was dismantled and rebuilt twice in New York City, and underwent a “gothic fantasy makeover” under British-born architect Frederick Sterner in 1910.

This Beaux Arts masterpiece is a glistening survivor as one of the few remaining and most architecturally intact Gilded Age mansions on the Upper East Side.
