arrangement of buildings relating to the entry road arriving from the west to the carriage loop at the front of homestead. Areas of the site associated with these early arrangements of structures are important and have archaeological potential. Stables were shown to the east of the loop and stock yards were shown to the west. Footings to the stock yard structures are evident in the service road's western edge. A kitchen building was shown to the north of the homestead and a garden area and gardener's cottage was shown to the east area beyond the stables. Paddocks, fence lines and entry roads were indicated. The site has potential to yield information regarding the other buildings of this 1852 plan. The Estate has somewhat lost its integrity due to the residential development in the southern portion of the estate. The Homestead Complex, including gardens, garden study, and farm complex, retain their integrity.
