One of the benefits attributed to dome houses is that a sphere encloses the most volume for a given surface area. Of course much of that volume is useless, but that is another story. Back in 1934, Everyday Science and Mechanics suggested some other virtues of spheres: they roll. The Smithsonian's Paleofuture quotes them:
If spherical, the house of the future can be easily transported to its building lot, set in place, and the fixtures added. The shell is first pressed into shape; then windows are cut, and only a protective tire is need for moving.... Properly built-in fixtures would even stand such moving.
Just make sure there are not dishes in the kitchen cabinets. More at Paleofuture
