About this home

Moonah House in Connewarre is the home & coastal studio office of Paul Baker & Sarah Drofenik of Baker Drofenik Architects. Built on land once covered by Moonah woodland, the project has been an ongoing process of learning & experimentation. From the outset, the house was conceived as an opportunity to explore high-performance construction & net-zero living through an airtight, highly insulated envelope achieving an 8.1-star energy rating within a modest budget.

The building comprises a three-bedroom home, separate studio, & open carport. Lightweight foundations & a low-carbon concrete studio slab were selected to reduce embodied energy, while timber is used extensively in both structure & finishes. Circular design principles informed material choices, with recycled elements such as remilled timber flooring incorporated throughout.

Built-in joinery was minimised to allow flexibility over time. The kitchen centres on a freestanding island made from low-embodied-energy materials, designed as a relocatable object rather than fixed cabinetry, an example of loose-fit design intended to avoid future landfill.

Following construction, a wildlife garden was established using locally indigenous species sourced from regional nurseries, including many Moonah trees to re-establish woodland character. The garden now supports numerous bird species, ground frogs, & spotted pardalotes nesting in the sandy soil.

Living in the house has provided direct experience of the benefits of high-performance construction. In winter, heating demand is minimal; often the warmth generated from cooking is sufficient to maintain comfort. Large double-glazed windows maintain a constant visual connection to the garden while reinforcing thermal performance

Key Ideas:
High insulation values
Passive house consultant calculations
Life Cycle Assessment at design stage
Soil from excavation was retained on site
Care during construction
Lift & slide doors
Tilt & turn windows
HRV Unit

Q & A

What motivated you to build or retrofit sustainably?
Bills, comfort, resilience, health, climate concerns, future-proofing and its essential to what we believe.
By constructing the house with high insulation values and airtight techniques, we have eliminated the temperature variations typical of a standard build. As a result, we rarely require heating during winter. In summer, we manage cooling during the day by utilizing power generated from our PV cell system.
We would absolutely build a high performance, airtight house again in this climate and location. However, one issue that has become apparent is the potential for overheating during summer. It is critical that north-facing eaves are included in the design and that external vertical blinds are provided for on the east and west elevations. While external blinds can be installed post-construction, they may be required for occupancy.
