Steward Brand, in "How Buildings Learn: What Happens After They’re Built", "asserts that the best buildings are made from low-cost, standard designs that people are familiar with, and easy to modify. In this way people can gradually change their buildings to meet their needs." (Quoting Wikipedia.)<p>One example was living in a trailer in New Mexico, which can be winterized by surrounding it by straw bales, then turned into walls, and expanded as needed. Another was living in an old wooden boat, on land, where it was trivial to cut a hole if you wanted it.<p>That's much in line with the philosophy behind this dome, which several others here agree with.<p>However, Brand also specifically dislikes domes, because they are difficult to expand, or to add internal divisions. For a single person, who does not need partitions or extra space, this is not a problem. (Nor would it be a problem if it were cheap to tear down and rebuild an entirely new structure.)<p>For a family or group of people, it is less tenable, as others here have also pointed out.
