Subdivisions of Garden Dome 2

Using standard 8 ft. lumber, the dome diameter will be approximately 27 ft (longest strut is 8 ft, one strut per board).Height will be 13′ – 6″ and ground level area will be 535 sq. ft.If two struts are cut from the board, diameter becomes 15 ft.If 10 ft. boards are used and two struts are cut from the board, diameter becomes 18 ft.These sizes are suggested for less waste of your board length and “more dome for your money.”Three basic additions of struts may be added to the dome.Designated X1, X2 and X3 these new dome frames offer added structure and strength, and added frame work for attaching roofing material.

The Garden Dome 2 - X1A

With X1 struts in the pentagons and X3 struts with 10 connector hubs added in the equilateral triangles between the pentagons. If long struts (brown) were 8 ft, dome diameter would be approx. 27 ft., so this would be an ideal maximum size for the 2 x 4 Garden Dome 2 (but could be larger especially if 2 x 6 lumber is used). Also a 4 x 8 sheet will cover two of the larger triangles; right triangles that are easy to cut with a hand held or table saw.

These representational illustrations depict methods of triangulating the faces of the basic Garden Dome 2 frame allowing larger/stronger domes possible. The faces of the original dome remain intact so as to allow sheet covering to be attached without having to cover each triangle seperately.
For a larger greenhouse using this dome type, the added struts might be 2 x 2 wood and aid in attaching the large sheets of greenhouse film or glazing, and supporting the cover under snow weight.
Several options are available for this and all of our domes:
Steel, aluminum or PVC hub connectors, regular or “heavy duty,” various sizes to support different dome types and strut dimensions, 1 x 2, 2 x 3, 2 x 4, or 2 x 6 wood domes, steel, and aluminum framework domes,
Galvanized hardware with superior anti-corrosion properties,
Connector Kits sent by UPS and complete Frame Kits shipped by UPS (smaller) motor freight (larger),
10.5 or 13 mil woven Super Poly, or the various double and triple wall clear polycarbonate products available, precut and ready to install.
Coroplast (brand) corrugated plastic sheets, precut for application.
Plywood or OSB sheets precut by us, ready to attach to your dome frame.
Plans for developing any dome into a garage, storage shelter or home with standard doors, windows etc. incorporated.
