IDEOLOGY - the house is the most essential of the basic structures mankind must have. It provides shelter, comfort, protection, privacy and expresses the individual's values in what is normally the biggest single investment a person will make in their lifetime.

It must achieve all of these practical things, but needs to have the ability to give joy to the occupier, whilst at the same time using resources of the earth in more sustainable ways. The use of materials that are efficient for their purpose, are more recyclable, can help reduce carbon footprint and use less energy to operate and maintain. To achieve all this, and also be more affordable in their 'initial cost' and 'useful life' cost.

THE SOS HOUSE - from the outset, the project intention was to involve as many commercial and supporting organisations as practically possible that could contribute and learn from the process. Major Participants, including BHI, saw this as an opportunity for the project to be useful during the whole process, not just as an end-product for display and information.

ENVIRONMENT - The design intent is to have a plan that maximises northern solar exposure, to minimise Winter heating needs and allow the most efficient solar control during summer. The sense of connectedness between indoor and outdoor spaces is emphasised on the north side with maximum operable glass areas and covered/paved transition areas. High raked ceilings over living and family areas add to the sense of light and space, whilst combining louvered high level ventilation modules that continue through the internal spaces allowing a controlled natural cross ventilation path for the entire house.

The inclusion of smooth floor surfaces, specialised paints and recyclable materials contributes to air quality, visual stimulation and harmonious texture inside and outside. The incorporation of Timbercrete® blocks is a significant contributor to the low energy demands of the building, whilst achieving visual delight from its warm, sandstone-like natural colour. As a contrast to the masonry patterning, small infill wall areas highlight the effectiveness of lightweight timber-based cladding products, matched closely to the timber windows and doors.

A lightweight, strong and colour-durable corrugated steel roof adds a roof texture that most Australians are familiar with. The incorporation of large-section recycled ironbark timbers in several major framing elements shows how attractive and useful recycled components can be.

Every visitor to the SOS House should take with them a memory of an educational experience that evokes joy and enthusiasm to translate that knowledge into their next home or renovation.
