in use, an early black locust/false acacia tree (Robinia pseudoacacia)(most likely from a former shelter belt), an 1850s line of elm trees behind (north of) the homestead (Ulmus procera), and early Aleppo (Pinus halepensis), Canary Island (Pinus canariensis) and Monterey pine (Pinus radiata) trees, holm/holly/evergreen oaks (Quercus ilex), honey locust (Gleditsia triacanthos)(also possibly from a former shelter belt), Irish yew (Taxus baccata 'Fastigiata') and funeral cypresses (Cupressus funebris). Three espaliered apple trees remain from 1918 and the garden reached its peak in the Twynam period of 1872–1969. The garden was restored by volunteers between 2010 and 2012, winning "best overall" category in a local garden competition in October 2012. An old well remains, possibly from the 1840s. Barn The stone barn is considerably earlier (1828) than the house and is the only surviving building of the "Old Township" of Goulburn as sited by Macquarie. It is probably one of the oldest buildings in Goulburn* . House Riversdale is a single storey, Colonial Georgian cottage with two wings forming a courtyard at the rear.
