Larger domes are possible with this type due to the large quantity of elements involved.

For a cost analysis send your requirements of construction materials and dome size.

These next views illustrate the "shortened version" - bottom level
of
triangles removed.

Base perimeter becomes slightly smaller than actual dome diameter.

For a 25 ft diameter dome, base perimeter will be 24 ft 2 inches from
vertex to opposite vertex.

Height from ground to apex will be 9 ft 3 inches.

This is a low profile dome, ideal for high wind areas and for a short greenhouse with good floor area that is easier to heat compared to a taller dome. By leaving off the lower level of triangles on the Garden Dome 4, the dome height is reduced by approximately 3 ft 2 inches for the 25 ft diameter model.

Height is approximately 37% of actual Dome Diameter

This one is 1/4 scale, actual dome size will be 12 feet.

**With 91 Connector Hubs and 250 struts, the Garden Dome 4 has
a lot
of parts! By following the economy parameter of sawing 2 struts per 8
ft
board (2 x 4, 2 x 6 etc.), the dome diameter will be approximately 26
ft.
and only 125 eight ft. boards are required. One can see how a 30 to 40
ft dome could easily be achieved using longer strut lengths.**

**Using the Connector Kit and lumber purchased locally, the 26 ft
2 x 4 dome frame can be built for under $1,600.**
