The main material costs are relatively inexpensive and sometimes even free when found on site.
Easy To Build
The techniques can be taught fairly easily to helpers. The structure goes up quickly with everyone pitching in.
Do It Yourself
You can do the work yourself with guidance from an experienced craftsman. Friends and family can pitch in to get it done quickly.
When the useful life of the structure has ended, the materials are recycled back into the Earth with no ill effects to the environment.
Benefits and Costs
A geodesic dome is a spherical or partial-spherical shell structure or lattice shell based on a network of great circles (geodesics) on the surface of a sphere. The geodesics intersect to form triangular elements that have local triangular rigidity and also distribute the stress across the structure. When completed to form a complete sphere, it is a geodesic sphere. A dome is enclosed, unlike open geodesic structures such as playground climbers.
Geodesic Domes Homes can be built of many different types of materials. Wooden domes have a hole drilled in the width of a strut. A stainless steel band locks the strut’s hole to a steel pipe. With this method, the struts may be cut to the exact length needed. Triangles of exterior plywood are then nailed to the struts. The dome is wrapped from the bottom to the top with several stapled layers of tar paper, in order to shed water, and finished with shingles. This type of dome is often called a hub-and-strut dome because of the use of steel hubs to tie the struts together.
Buckminster Fuller named the dome “geodesic” in 1948. The geodesic dome appealed to Fuller because it was extremely strong for its weight, its “omnitriangulated” surface provided an inherently stable structure, and because a sphere encloses the greatest volume for the least surface area.
