Generic Geodesic Structures
True geodesic domes are mathematical constructs which allow a collection of flat triangles to mimic or approximate a spherical shape. To achieve this, a number of pentagons and hexagons appear in much the same way footballs appear with a number of flat polygons stitched together.
There are many sites which describe the history, mathematical elements, and application of geodesic structures. Some of the more famous include the giant Eden Project domes in Cornwall.
In practice, geodesic domes become increasingly complex as the size increases. This complexity is understood as the “frequency” of the dome and effectively begins with a 2v (or 2-frequency) structure. To produce a hemispherical 2v dome requires 65 poles (of two lengths) and 26 junctions or “hubs”. Smaller domes from 4-7m are often made to this design.
Our domes have been made to a 3v design involving 120 poles and 46 hubs. We use slightly less than a hemisphere to allow more economic use of canvas and less height for ease of construction. These domes range from 8 to 14m in diameter and are the domes shown on this website. We are able to provide larger domes of 4v or higher frequency, or smaller 2v structures on request.
All these structures can be linked to produce geodesic complexes utilizing any of the various size of domes. We create special link canvases to allow fully integrated spaces, or alternatively more “door” like openings when more separate pod-like rooms are needed.
