Loder House, Georgian townhouse in Windsor, New South Wales, Australia

Loder House is a brick townhouse in Windsor with two stories and architectural details characteristic of Australian Georgian style. Located on George Street, the building displays the design features typical of its era.

The house was built in 1834 by George Loder Jnr for his family and later changed hands several times. From 1874 to 1889, a trading bank operated a branch from within its walls.

The house sits on land where the Dharug people once relied on the nearby Nepean River and South Creek for food and travel. This connection to the original inhabitants remains part of the place's story.

Loder House stands at 126 George Street in Windsor, on the main street of the town laid out after Macquarie's 1810 proclamation. The building is a private residence and not open as a museum, so visitors see the facade, the cast iron lacework and the stone walling from the street. The brick outbuilding and boundary fence are covered by the same 1979 conservation order.

A fire in 1973 damaged the house partially, but public support prevented its demolition. The building retained its original nineteenth-century construction elements throughout the crisis.
