Geodesic Domes:
Geodesic Dome is using triangular networks forming hexagons and pentagons and creating a free-span, spacious environment of spherically shaped structure requiring no internal supports. This results in large flexibility for utilizing interior space to implement floor designs not limited by structural restrictions. Because of the structural strength of the shape, the domes have a far better record of withstanding tornados, hurricanes and earthquakes than cube-shaped structures of conventional homes.
Advantages:
Material Cost:
Geodesic domes provide the greatest amount of floor area with the least
amount of surface area, reducing the quantity of needed building material
by as much as 30-50%.
Energy Efficiency:
As a result of the shape, the dome has approximately 30-50% less roof
and wall area than cube-shaped home of equal floor space. This
results in lesser area being exposed to the
elements, resulting in reduction in heating and cooling costs of
dome shaped structures. Also, the spherical shape of the dome facilitates
natural air flow yielding more even temperatures maximizing overall
interior temperature comfort.
Disadvantages:
As a result of complicated angles, the interior and exterior finishing
of the dome (after spedy assembly of the prefabricated shell) is
significantly more labor intensive than finishing the
conventional house. Also, the finishing work requires highly
skilled or specialized tradesmen which might not be available at
every location. These factors might present welcoming challenge for
skilled handyman - homebuilder, but would create substantial
cost outlay if the hired labor is considered.

Circular Homes:
The circle is the strongest geometrical shape we recognize, and this factor likely influnced builders of circular homes for thousands of years. Prefabricated circular buildings have been built as cabins, studios, homes, offices or community halls and convention centers.
Most of today's prefabricated circular homes and cabins offered across the country use conventional wood-frame or post & beam construction method. These homes and cabins are ideally suited to take the full advantage of locations offering exciting panoramatic views, and to incorporate factor of the surroundings into the home design.
