Glenalvon House, Georgian colonial residence in Campbelltown, Australia

Glenalvon House is a two-storey Georgian sandstone residence with a symmetrical facade, a stone-flagged verandah on turned Doric columns, and shuttered French doors either side of the central entrance. Five double-hung nine-pane windows light the upper floor. To the rear stands the former stables, a rectangular sandstone building with a central gable and loft doors above the entry.

Michael Byrne, son of an Irish rebel, built the house in 1841 during the early settlement period of New South Wales. Its construction reflected the wealth and stability of settlers during that growing colonial era.

The house preserves original cedar joinery and marble fireplaces that show the craftsmanship of early European settlers. These details reflect how wealthy families in the 1800s designed their homes.

The Campbelltown and Airds Historical Society operates the property with guided tours through the house, gardens, and outbuildings on selected Mondays and Saturdays. Visitors should check in advance as opening times vary and are not available daily.

The stables behind the house were likely built after 1840, since they appear on no early town plan and differ in style from the residence. Their roof framing was recorded in 1973 as jointed, dowelled, pegged and numbered without a single nail. The stables now serve as a resource centre for the historical society.
