The Owl Woods Passive House in Trentham, Victoria was designed to Passivhaus standards which allows for stable indoor temperatures, healthy indoor environment and low running costs. Designed by Talina Edwards Architecture, the home achieved Passivehaus certification by creating a well insulated and airtight building envelope with openable triple glazed windows, controlled ventilation and elimination of thermal bridges. Additionally, the home was orientated using passive solar design principles.
The home was designed as a cluster of farm sheds or birdhouses, whilst reminding the owners of the Scottish village where they previously lived.
The pitched roofs stretch to the north like a birds beak, providing summer shading. The roof then folds down the western side like a wing protecting the home from the strong western summer sun.

Materials were chosen that are natural, healthy, durable and sustainably sourced, relating back to the Australian landscape and minimising embodied energy wherever possible.
Rather than just being ‘tin sheds’, lovely radial-sawn native timber cladding was introduced to complement the grey corrugated steel, and soften the overall feel of the home and create that connection back to the surrounding bushland.
