Bilby House
This architectural style reinterprets the classic barn silhouette—steep rooflines and simple, geometric forms—through a contemporary lens. The result is a refined blend of rural charm and modern clarity.
This building is designed to be modular, with a 6 metre wide single pavilion structure that can be expanded in length to suit the brief and budget. The striking 45 gable roof lines create an immense sense of volume over the living zone, and also the ability to fit out a compliant habitable attic space. A portal frame design is based on 3.6m grids, allowing for expansion of the building in design phase. Exposed timber portal frame internally, lending itself to a plywood or OSB internal wall and/or ceiling linings. Whilst not essential, this building has been designed with SIPs construction in mind. Because of the small footprint, this building is well suited to a range of environments.
The Bilby Cabin is available in three sizes, each offering a thoughtful balance of comfort, functionality, and simplicity.

What’s in a name?
The Bilby House is named Greater Bilby a small marsupial once found across 70% of Australia. Today they are found in the desert regions, and use their strong foreclaws to build extensive tunnels to escape the heat and predators. Their main threats are competition for food from livestock and introduced species such as rabbits, and predators of foxes and feral cats.
