Rare Development & Renovation Opportunity – The Historic Hadley Farm House

5-Bed Landmark with Sunroom, 2-Car Garage & Expansive Yard on 0.35 Acres (Zoned R4)

Step into history with the Old Hadley Farm House—an extraordinary 5-bedroom, 2.5-bath treasure believed to be the oldest surviving residence in the Bronx. This stone and wood-frame home may date back as far as 1747, predating even the Van Cortlandt Mansion, and has been a designated New York City landmark since 2000.

Full of character and potential, the central portion of the home boasts nearly two-foot-thick stone walls, original wood beams crafted from halved tree trunks (bark intact), and a historic stone fireplace. Expanded over time, the home features a north wing from the late 19th century and a south wing designed by renowned architect Dwight James Baum in 1915–1916.
