What’s old is new again — so much so that this home, rumored to be the oldest in The Bronx, is newly available for sale. Even if it isn’t, the Old Hadley Farm House — a five-bed, 2.5-bath residence located near Fieldston — is certainly one of the oldest surviving dwellings in the borough. It listed this week for $1.49 million, according to StreetEasy. “It really tells the story of New York in one house. And it’s not like you drive along a tree-lined driveway to get there. It’s smack dab in the middle of your of a regular-looking Bronx Street,” Nick Dembowski, a historian at the nearby Van Cortlandt House Museum, told The Post. The landmarked residence spans 2,660 square feet and includes a sunroom, a detached two-car garage and a large yard on 0.34 acres. A historic stone fireplace and 2-foot-thick-walls add to its extra-old world charm. No one has been able to date, with certainly, the home’s original stone structure. Unconfirmed claims of the home’s existence in 1747 would predate even the Van Cortlandt Mansion, which holds the confirmed title of oldest residence in the borough. That year would even predate the United States. Not even Dembowski, who extensively profiled the property for the Kingsbridge Historical Society, can say far back the home goes. A tenant farmer named Isaac Green was the home’s first recorded occupant, in addition to five enslaved people. There is little information on his residence before the American Revolution. William and Elizabeth Hadley purchased the home and its property in 1786. The Hadley Farm House saw its fair share of action during the war, when local skirmishes between rebels and British troops were commonplace. The home served as a British outpost when, in 1778, an audacious French office led rebel troops on a night raid of the property. Colonel Armand, according to records cited by Dembowski, snuck up on the troops in the dark — their lookout guy was apparently drunk — and “kind of slapped them around a little bit and humiliated them.” The rebels, according to one account, gave the troops at Hadley Farm House “a very sound drubbing.” Armand proudly documented his exploits in a letter to George Washington. The home assumed its current form in 1915, according to the landmark designation report, with an expansion and renovation by renowned architect Dwight James Baum. Baum totally overhauled the home, but maintained some of its oldest details, including wood beams crafted from halved tree trunks — bark intact. Property records indicate that the property last changed hands in 1999. The current owners listed the property in 2024 for a higher $2.25 million, but found no takers. The listing’s current broker, James Endress of Julia B. Fee Sotheby’s International Realty, said the property is “basically in estate condition.” “It’s in disrepair, anyone driving by the house can see,” Endress said. The exterior of the house is landmarked, so it will require special care and expense in its restoration, but the detached garage is not. A new owner could tear it down and subdivide the 20-something-foot lot, Endress said. Selling it to an investor could offset the new owner’s inevitable renovation costs. The listing urges buyers to “bring your architect and your imagination.” “My sincere hope is that whoever ends up buying this house has the means to really preserve it, because it does need a fair amount of preservation work,” Dembowski said.
