The name 'Seven Hills' is thought to be affiliated with Matthew Pearce, a settler in Sydney who was granted 160 acres (65 ha.)

[3][4] Prior to European settlement in the 1790s, the area now known as Seven Hills was originally settled and occupied for hundreds, if not thousands, of years by indigenous peoples who most probably would have identified with the Warmuli and Toogagal clans, of the Darug nation.

Matthew Pearce (1762–1831) was granted 160 acres (65 ha)) in 1795, which he named after Kings Langley in Hertfordshire, England, where he was said to have been born.

In the period 1959 to the 1970s, housing schemes excised land that was previously part of Seven Hills to create the suburbs of Lalor Park and Kings Langley.

Chadwick commissioned a Sydney architect, Byera Hadley (later to become the leading architectural academic in NSW), to build a large house on the land which he named "Melrose".

[11] A much smaller house known as "Drumtochty" had been built around 1890 on the estate, to the south, at the corner of Seven Hills Road and what is now Australorp Avenue.

In 1912 the company appointed James Hadlington who concurrently held the position as the state Department of Agriculture's "Poultry Expert".

By 1917 Australia was confronting the problem of providing suitable employment for both able-bodied and disabled veterans of the First World War.

The transfer took place in July 1917 and the area of the farm nearer Seven Hills Station fronting (what is now) Grantham Road was subdivided into eleven 5-acre (20,000 m2) blocks for married men with the balance becoming a poultry breeding, stock and feed storage and training facility named "Grantham State Poultry Farm".

[13] Initially the ex-servicemen trainees on the farm were housed in tents but by 1918 barracks-like accommodation had been put up near Seven Hills Road.

As with other such schemes some of the settlers found it hard to make a living from agriculture despite establishment loans and sustenance payments and by 1922 some of the original occupiers had abandoned the project leaving the blocks for other ex-servicemen to take over.

In 2008 a plan for the use of the administration building as council offices and the development of the lands as a heritage park was announced and public comment was invited.

Note the plethora of signage, traffic calming devices and utility poles strung with overhead power and TV cabling typical of streetscapes in western Sydney.

[20] Seven Hills railway station is a major interchange on the North Shore & Western Line of the Sydney Trains network with in excess of 2000 commuter parking spaces.
