Harrington Park (homestead) the estate comprised 800 acres of cleared land, pasture and forest with crop paddocks and a vegetable garden near the house. A second driveway approaches the homestead complex from within the new suburb of Harrington Park, off Parkway Drive / Cobbitty Road/ Oran Park Drive to its north via the new suburb and off the Northern Road to the west.

Today the garden retains many mature coniferous and other trees
