In 1852, Campbell leased the house to James Scott. By this time, the house had six rooms. Campbell sold Lochend to Scott in 1858 for 2,600 pounds, and Scott lived there until 1875. The Scott family enlarged the house to eleven rooms, a stable, coach house and cottage, all surrounded by vegetable and fruit gardens and 58 acres of crop growing land. The next owner, retired sheep farmer David Mundy, built the two-storey house Lochiel Park, on a rise just to the south of Lochend. From 1898 to 1957, Lochend and Lochiel Park were owned or lived in by members of the Hobbs family. The Hobbs sold both houses to the SA Government in 1947, and Lochiel Park became a junior boys' reformatory.
