[1] The land which Jonas occupied at this time was considered by him to be "too poor and limited in size" to enable him to cultivate tobacco to the extent he wished.

As a consequence he petitioned Governor Brisbane in 1822 for a grant of land in the Burragorang district where he proposed to "cultivate tobacco to a considerable extent, as the soil is extremely suitable for that purpose".

[1] In 1836 William Bradley opened a brewery complex at the base of the hill below Lansdowne homestead and between 1836 and 1840 a steam-powered mill had been added.

After Bradley's death in 1868 the complex was sold to Messrs Walford, Sparks & Emanuel who continued the milling but ceased the brewery operation.

[1] Reduced in scale, but still an agricultural property with paddocks of grass running adjacent to Bungonia Road and the Mulwaree Chain of Ponds (river), and more recently a vineyard block north of the house.

Former property straddled the river with the Flour Mill & Brewery & Malt House complex to the west and further fields to the north.

Shelter belts of Monterey pine (Pinus radiata), Monterey cypress (Cupressus macrocarpa), black locust (Robinia pseudoacacia), stone pine (Pinus pinea)[1] Single storey colonial style hipped roof (corrugated iron today, shingles originally) U-shaped house in lapped timber boards, cedar fireplace mantels and much internal joinery, stringybark/spotted gum floorboards, open verandahs on three sides, two side verandahs filled in (south) and part-filled in (north).

[1] Single storey double height stud building north of house, in random rubble stone construction, corrugated iron roof (today), with ornamental grape (Vitis coignetae) on one side.

Crystal chandeliers, ornate ceiling cornices, large cedar framed windows, open fireplace.

[1] Long low single storey block north of house, brick with corrugated iron roof.

[1] Random rubble stone (quarried from the surrounding hills) construction, open stable component (majority of structure) and small room on northern side with brick fireplace.

Single storey brick, corrugated iron roof, verandah on western side and southern return.

Northern wall has semi-circular protruding section with pointed gothic arched window spaces (3) - in ruins as a shell today.

It provides physical evidence of its establishment and occupation by one of the most powerful men in the colony who played an important role in shaping the development of NSW.

The homestead forms part of an intact group of buildings which have the potential to provide a complete vignette of 19th century rural life and activity.

[1] The property exhibits strong associations with the Aboriginal population as it was used as both a meeting place and burial ground.

[1] The property provides physical evidence of the close association with one of the earliest industrial enterprises in Goulburn.

[1] Lansdowne's location on a spur overlooking the flood plain has enabled a strong relationship to develop between the city and the rural hinterland.

[1] The site has the potential to provide valuable archaeological information about both Aboriginal and European periods of occupation.
