Beyond ArchiBlox’s speedy construction time of 6 weeks, prefab suited the clients desire to tread lightly on the land with the Avalon House project. With modular building the impact on the surrounding environment is heavily reduced during construction. The dwelling is outfitted with a number of green features, including a living roof that minimises rainwater runoff and solar penetration. The green roof also acts as a thermal mass, an east-west orientation that allows cross-ventilation. Avalon House is beautifully wrapped in FSC certified external blackbutt hardwood timber milled from sustainably forestry methods and Colorbond corrugated iron – marine grade. By fabricating off-site, ArchiBlox also had careful control over material usage with minimal wastage. Tom Ross and Michael Wickham
