A house hidden in the hills or in the back country may be rather plain but very aesthetic to the owner, partly because it is comfortable and economical. The same house located at the center of attention in a high-density, residential area, consisting of more conventional construction, may be considered undesirable or even ugly. Aesthetics usually consider the type of building and how it associates with its surrounding conditions. Comfort and aesthetics need not greatly increase costs. A beautiful and functional concrete dome building can provide the economy with safety and comfort desired easier than any other building system for some locations.
