The sphere is the strongest & most efficient geometric shape.  It is the fundamental structure of the universe which can be seen in everything from atoms, cells, planets & stars.

The Geodesic Dome replicates the structural strength, integrity and efficiency of the sphere by approximating it with a polygon.

While there are many types of polygon’s that can approximate a sphere; the 20-sided icosahedron, is the fundamental and preferred polygon to use as the base shape for our geodesic domes.
