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. When you get the “first draft” of the plans for your new home, go over them thoroughly and make sure everything fits together geometrically. Know how to read house plans, and question any empty spaces that you just can’t visualize. Mint Images - Tim Pannell / Getty Images Halfpoint / Getty Images Save money by doing your homework.
