Sprawling 1930s estate long owned by the wealthy Phipps family lists for $23M

An old-money mansion from another generation of Long Island wealth is seeking its first non-bloodline owner.

This newly listed Old Westbury property, built in the 1930s for Howard Phipps — whose father, Henry Phipps Jr., was Andrew Carnegie’s partner in Carnegie Steel — has remained in the family since its construction, Mansion Global first reported.

The seller is Howard’s son, Howard Phipps Jr., who’s seeking $23 million for the grand address — named Erchless for a castle in Scotland that the Phipps family frequently visited.

Previously, in 2018 , the seller sought $29.99 million for the “Great Gatsby”-esque estate — but did not end up parting with it.

“Erchless is one of the last remaining great estates of a bygone era situated on 92.7 acres with an impeccably maintained manor house with award-winning rhododendrons and gardens that are regarded as among the best of the Northeast,” Lois Kirschenbaum of Daniel Gale Sotheby’s International Realty, who holds the listing , told The Post.

The U-shaped, 16,000-square-foot manor house boasts such decadent details as nine fireplaces, seven large bedrooms, 12 bathrooms, a curved staircase and floor-to-ceiling windows in both the sunroom and the breakfast room. As for those windows, having been built on elevators, they “can be lowered into the basement to transform these rooms into outdoor space,” Kirschenbaum added.

There are original moldings throughout the Georgian Colonial-style abode as well as modern comforts, Mansion Global noted.

On the grounds, in addition to the gardens and meadowlands that “are all organic,” there’s also an original milking barn from the Quakers that dates to 1601, four greenhouses, a chauffeur’s house, a carriage bard and a cow barn.

Phipps Jr., who is pushing 90, declined to be interviewed by Mansion Global. But in 2018, his former listing agent told the Wall Street Journal that Phipps had decided to part with the property because he was looking to downsize in his sunset years.
