With super efficient design, high levels of insulation throughout, and double or triple glazing, OFFGRID-INSTYLE homes require very little energy for thermal comfort in both hot and cold climates, making them perfect for low-cost living or off-grid situations requiring a solar power system.  They're also robust, low-maintenance, stylish, and can easily be modified to comply with maximum bush fire and cyclone ratings.  In Australia and New Zealand, the complete list of materials for the ECO-CABIN range of designs (including windows, kitchen cabinets, and fixtures) can be ordered from Bunnings, making it essentially a kit home that can be built on site by a small team of local carpenters.  Detailed construction drawings and comprehensive materials order lists are available for purchase here.
