Johnston and his wife Estelle Borhek Johnston lived in the 6,000 square-foot (557 m sq) "big house" until his death in 1948 and her death in 1952. Johnston and Estelle died at home; Estelle's funeral was conducted at the home two days after her November 17, 1952 death. Housenick Park, a passive recreation area, does not have playing fields or recreation equipment. Instead, paths lead through the park and the adjoining Archibald Johnston Conservation Area along private roads laid out by Johnston in the 1920s. The current trails lead from the parking lot to the Archibald Johnston Mansion (referred to as the "big house"), then along the Monocacy Creek to the south to the bird blind and cement bridge. Another trail along the Monocacy goes north to the spring and pump house. A third trail goes directly from the spring and pump house area back to the parking lot. Two interpretive kiosks (parking lot and at north end of park at abandoned railroad crossing) provide information about notable features. Trash containers are located at the parking area. A new parking lot under construction during the summer of 2015 will open in the fall, and will accommodate 20 to 30 cars. The existing interpretive kiosk will be moved to the new parking area. Drinking water is not available at the park. A porta potty is provided by Bethlehem Township.
