Dunmore House, Georgian homestead in Bolwarra Heights, Australia

Dunmore House is a Georgian homestead with stone outbuildings arranged around a courtyard at 557 Paterson Road in New South Wales. The buildings feature a flagged verandah, sash windows, and cedar joinery alongside an original cantilevered stone staircase from the Colonial period.

The estate was built between 1830 and 1833 by William and Andrew Lang and named after Mary Dunmore. Its early operations relied on assigned convict labor for agricultural work on the property.

The name Dunmore comes from Mary Dunmore, wife of William Lang and mother of Andrew and John Dunmore Lang, the colony's first Presbyterian minister. John Dunmore Lang urged his brother George to emigrate and later inherited the estate before passing it to Andrew.

Dunmore House stands at 557 Paterson Road, Bolwarra Heights, in the Hunter Valley. The sources record no public opening, tours or visitor facilities, so the site should be treated as private property and viewed only from the public road.

The land was first granted to George Lang in 1822, and he named the property Dunmore after his mother Mary Dunmore. George died in Sydney in 1825 aged 23, and the estate passed to his brother Andrew, who reportedly paid 5 shillings for it.
