If you'd like an affordable, all-electric, emission-free, off-grid home built on your own block of land, you can purchase plans of the 3 bedroom SOLARHOME200 on this website (with immediate download in PDF format) and copies of the plans can be given to local builders for competitive quotes, which is usually the most economical way to build. The full set of detailed construction drawings for only $7,000 is great value, especially considering that this is a truly innovative design which has taken three years and almost a million dollars to research, design, build, and performance test. The drawings consist of 18 pages (the first 4 pages are shown below) to scale at A3 size. They come with full technical support and advice during the construction period, while additional design work and alterations to the drawings are charged at $170/hour. Standard, readily available building materials are specified throughout.
You will need a local builder willing to follow the specifications exactly in order to achieve the energy efficiency required. You will also need a local building designer/draftsman to prepare a site plan and to help submit your building application to local authorities by organising reports and drawings from a surveyor, structural engineer, geotechnical engineer, and whatever other information your particular council may require. Like all houses, the build cost will depend largely on the materials, finishes, and fixtures you select, where you live, the specific building site, and how busy local builders happen to be at the time. But although some features of the SOLARHOME will add to the overall cost, the compact, uncomplicated design and simple detailing save time and money, so it may cost no more than a normal house if you select a willing builder, stick to a tight, well controlled budget, and diligently shop around for supplies.
