The costs of the brick veneer skin and the requirement for steel support bars over openings makes it a more costly solution than using lightweight sheet products. It would be costly to reproduce the overhangs and window sizes that are in this house if brickwork were used. In addition, the heavyweight brickwork requires a metal scaffold, not an aluminium one, which is more expensive to hire. The labour time required for brick installation is typically longer than sheet cladding so, again, the scaffold stays up for a much longer period of time and therefore incurs more cost. • reduced scaffolding costs. Building a traditional roof is more time consuming and costly as it also requires a scaffold in place for a longer period of time. The sandwich panel roof solution is installed in half a day using two carpenters where the traditional trussed roof and ceiling system uses up to five different subcontractor teams and typically occurs over a two-week period. looKhoMe 17

In its most compact form, fronT & rear eLevaTion The smarter small home has been designed for a rear-loaded lot with the house at the front. Instead of having a front yard and backyard, there is one sizeable yard. “we haven’t got a big driveway and wasted 120 square metres,” Blacklow says. “Instead we’ve just used 30 square metres for the front.” If the home is to be used on lots that aren’t rear loaded, they’ll probably be slightly bigger blocks. For example, side eLevaTions a large Queensland developer has already commissioned five smarter small homes after seeing a sneak preview. They will be built on 15 metre wide lots.

According to the chairman of the National Appliance and Equipment Energy Efficiency committee, Dr Tony Marker, one watt consumed in stand-by is, as a general rule, approximately equal to $1 per year. A single appliance using eight watts of power in stand-by will add approximately $8 per year to your electricity bill. stand-by power consumption accounts for up to 10% or more ground fLoor of Australia’s household electricity usage. This costs Australian households more than $5 billion and generates more than 5 million tonnes of carbon dioxide per annum.

As a consequence, there are no hallways. Blacklow says they’ve also tried to use a lot of combined rooms and, in some ways, they’ve reverted back to features popular in the 1950s, like eat-in kitchens. Instead of separate kitchen, dining and living rooms that aren’t all necessarily well used, the designers have created a large room with a kitchen at one end with space for a large table that can be used for food preparation and dining. Alternatively, a mobile kitchen preparation bench and a smaller dining table can be used.
