Sustainable House Tour – Wallaroo
This house uses a combination of both conventional and alternative building techniques to meet the international Passive House standard. The straight lines and square corners mean that it is not initially apparent that three of the four external walls are constructed from straw bale, with a lime-based render.
The house takes advantage of the northern sloping block to maximise solar gain. While the initial design was not intended to meet the Passive House standard, the owners have implemented a range of different technical solutions, to align with these principles, while ensuring that the aesthetics of the house were not compromised. The house has met all requirements for Passive House certification and this process will be finalised over coming months.
Some of the key features of the house include:
- Thermally broken triple glazed tilt-turn windows
- Raked ceilings
- Positioning of windows and doors to improve ventilation
- Polished concrete floors and bench tops
- A combination of recycled and locally milled timber for key features and structural elements
- Internal and external fire suppression systems
- A minimum of R8 insulation in the ceiling and straw walls, with minimum of R2 under slab and along the structural wall
- It meets the airtightness requirements using a rendered straw bale finish
There will be a projector and slide show running during the tour to provide insight into some of the techniques that were used to achieve air tightness with rendered straw bale walls.
Please note that this house is still under construction and access to the site includes a 50 metre return walk, down a steep track. If this is likely to present an issue, please advise at the time of booking.
