The house is now the cornerstone of this historic district, spanning both sides of the river. Three additional buildings were moved onto the adjacent property of the Bergen County Historical Society, a private non-profit volunteer organization. The Demarest House was moved here from New Milford in 1956 and is maintained by the Blauvelt Demarest Foundation. The Westervelt-Thomas Barn was relocated from Washington Township in 1958. The County of Bergen moved the Campbell-Christie House here to lands of the Bergen County Historical Society in 1977. The Society erected a working replica of a Bergen Dutch Out-Kitchen in 1991 and an outhouse in 2009.
