Bunya pines (Araucaria bidwillii), hoop pines (Araucaria cunninghamii), English elms (Ulmus procera) which have suckered into thickets in places, kurrajongs (Brachychiton populneus), white cedars (Melia azederach var.australasica), English oaks (Quercus robur), shelter belts/former farm hedges of American Osage orange (Maclura pomifera). Osage oranges are now extremely rare in the Sydney basin - only two other examples are known, at Hambledon Cottage, Parramatta and Muogamarra Nature Reserve, Hornsby. The Osage orange hedges north and south of the house on its eastern side date to the time the house was first occupied. They have historical significance as part of the early fabric of the place and their association with the Antill family, and are an integral component of the landscaping. Other early plantings include false acacia (Robinia pseudoacacia, again probably originally shelter belt plantings), again suckering into thickets. Farm Building Complex Homestead The (now Golf Club-) house was built in 1863 by John Macquarie Antill, hence the name of the Club, Antill Park Country Golf Club. It was first named Jarvisfield, commemorating Governor Macquarie's first wife Jane Jarvis' name and the fact that an Antill had been long-serving aide-de-camp to and a friend of Governor Macquarie. The homestead's verandah overlooks the course and is frequented by locals and visitors who wish to analyse their round, the treachery of the greens or simply enjoy the serene views throughout the course. A two-storey, rendered brick, Georgian Revival country villa with flanking single storey wings which form the sides of the rear courtyard. The hipped roofs of main house and wings are slated and have rendered brickwork chimneys with simple neck mouldings. The single storey verandah lining the front and part of the two side elevations retain their original flat timber columns (but has a new roof following the removal of an Edwardian double storeyed verandah). The new roof line follows the original which was retained in the side return roofs. The front door is flanked by French doors with 2 x 6 paned sash windows to the first floor. On the side elevations blank window recesses maintain facade symmetry at first floor level. The rear elevation is dominated by a large round-headed stair window. Barn The site also contains a mid-19th century stone barn. The barn is a simple gable-roofed structure of coursed sparrow-pecked sandstone with exposed timber beams and rafters. Following the site's conversion to a golf course the barn was reused as
