Kellyville is named after Hugh Kelly, who owned the Kellyville Estate. Kelly owned a hotel on the corner of Wrights and Windsor Roads called the ‘Bird-In-Hand’ prior to his death in 1884.
For most of the 20th century, Kellyville was semi-rural. From the 1960s to the 1980s about 900 homes were developed in an area around Acres Road, known locally as 'The Village'. More recently, major developments such as Kellyville Plaza, which include a Coles supermarket and 22 specialty stores, have encouraged residential growth. Due to the suburb's location, Kellyville is a major growth area in The Hills.
Kellyville possesses a unique combination of being semi-rural, older suburban and modern. Through its combination of housing, the area is able to offer a variety of lifestyles, spanning from medium-density townhouse developments along Kellyville Shopping Plaza to opulent residences sited adjacent to natural creeks and bushlands. The ease of commuting to Sydney’s CBD as a result of the introduction of the Hills Bus along with dedicated bus lanes on the M2 motor way has seen Kellyville expand rapidly due to it’s popularity.
