Bilby House

The Bilby House is the modular entry to the AlterecO2 range — a compact, flexible design equally suited to urban sites or rural retreats.

The layout includes two bedrooms, one bathroom, and a mezzanine level, with a total floor area of 70m² plus an additional 22m² of usable mezzanine space. Its 6-metre-wide single-pavilion form is designed for modular expansion, allowing the home to grow in length to suit your brief and budget.

A steep 45° gable roof creates generous volume over the living space, while enabling a compliant, habitable attic level. The structure is based on 3.6m portal frame grids, supporting design flexibility and future adaptation.

Internally, the exposed timber portal frame lends itself beautifully to plywood or OSB wall and ceiling linings. While not essential, the Bilby has been designed with SIPs (Structural Insulated Panels) in mind — offering a simple pathway to a high-performance build.

Its small footprint, adaptability, and structural efficiency make it well suited to a wide range of site conditions.

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.

We celebrate and acknowledge our connection to the land—each of our homes is named after an endangered Australian animal, highlighting the impact of development on native habitats. As part of this commitment, we donate a percentage of our profits to Bush Heritage Australia to help protect and restore biodiversity.
