SHR Criteria a)
[Historical significance] | Hadley Park is a rare example of a farmhouse from c1811-1812 and it possesses on the site a single storey outbuilding which may be an earlier cottage dating from c1806. Hadley park is the oldest example amongst a notable group of surviving farmhouses and other dwellings in the Castlereagh area, an early centre of agricultural production. The property has the ability to demonstrate its relationship to the farming of its surrounding farmland and the continuing agricultural land use of the district which survives from the late 18th century (G. Edds 1996: 6) |
SHR Criteria c)
[Aesthetic significance] | The main farmhouse is aesthetically distinctive and is a landmark within the Castlereagh farming plateau. The main farmhouse is outstanding because of its integrity, its rural setting and its fabric intactness (G. Edds 1996: 6) |
SHR Criteria d)
[Social significance] | The main farmhouse in particular was built for Charles Hadley, a notable example of the second wave of settlers in the area who successfully made the transition from a subsistence to a market economy. The property has had an association with the Hadley family and its descendants from its construction until the present day, an association almost unrivalled for continuity and length of time in Australia. The farming complex, together with 'Nepean Park' adjacent, make an outstanding pair within the Castlereagh/Nepean River farming plateau. (G. Edds 1996: 6) |
SHR Criteria e)
[Research potential] | The single storey outbuilding, possibly the earliest timber cottage on the site c1806, maybe the o0ldest timber cottage known to survive in Australia. The main farmhouse is an extremely rare surviving example of a jerkin head roof structure embodying a most unique and unusual timber structure and clad externally with brickwork. The technical excellence of the timber roof structure is paralleled by 'Elizabeth Farm' Parramatta, 'Old Government House' Parramatta and 'St. Mathgew's Anglican Church' Windsor and because of this technical excellence the building cannot be described as vernacular. The single storey outbuilding and main farmhouse's relative intactness of form, interior spaces and detailing, dating fro0m c1806 make the building precinct a rare survival of the earliest period of colonial architecture in Australia (G. Edds 1996: 6) |
SHR Criteria f)
[Rarity] | The Hadley Park property containing the improvements thereon is considered to be very rare/scarce and of State significance. (G. Edds 1996: 6) |
