I''ve just built my first dome. It''s a 16 foot diameter vertex-up icosahedral 2v fruit cage. I wanted it to be cheap so it''s made from treated 2x1 which cost about £70 and the struts are lashed together around the hubs which are 2" lenghts of 2" diameter wooden post. It''s the simplest design possible - though it was still an eventful enough build. It was my third attempt - first two used circles of blue plastic water pipe and then bamboo, but both neither worked for me. Future plans are for a site hut on the allotments, a bit bigger and probably higher frequency. I''m also interested in the possibility of giving it a super-ellipsoidal profile to improve the head-room, but that really ramps up the complexity. I''m thinking about roofing it with a green-roof on top and then tiles cut from old tyres.

Looks cool Simon, are you going to cover it, you said fruit cage would that be to grow fruit up or net over to keep the birds off?
A 16 foot diameter dome frame for £70...Absolute bargain.
For your site hut try a 3v 4.5m - 5m dome, plenty of headroom and good door size in a 5/9. If you've not done 3 frequency before you will find it only a tiny bit more complex than a 2v. When you've done one you won't go back to 2v.
Thanks Paul. I'm going to drape a net over it and grow fruit under it, but it's inspired me to think about another smaller one just as a growing frame.
A 4.5m 3v 5/9 is a good call with that extra head-room, and a finished height just under that pesky 3m planning-permission ceiling.
