Choose Simple Shapes
Curves, triangles, trapezoids, and other complex shapes are difficult and expensive to build by your local contractor. Choose square or rectangular floor plans. Avoid cathedral ceilings and complicated roof-lines. The possible exception?
You could forget the box and opt for a dome home, like Solaleya’s Domespace model shown here. “Our designs are guided by nature’s spontaneous proportions (the Golden Number: 1.618) to enhance structural strength and promote a sense of well being,” claims the Solaleya website.
“Think of a soap bubble,” explains Timberline Manufacturing Inc., another maker of geodesic dome kits. “A sphere represents the smallest amount of material surface area needed to enclose a given volume of space…The lower the total outside surface area (walls and ceilings) the greater the efficiency in energy use for heating and cooling. A dome has approximately one-third less surface area to the outside than a box-style structure.”
Geodesic domes and other space-frame structures are often sold as kits, with prefabricated panels and pre-cut and pre-drilled numbered and color-coded parts. As they say, assembly is required.
