A geodesic dome is easy to build with Star Plates. Mike Hauser and I put one together a while back.
Star Plates are metal plates that you attach boards to and hold them uniformly.
Basically, all you need is the Star Plates, some nuts and bolts, boards and a couple of wrenches, preferably sturdy tools you like. It's an easy way to put up a sturdy structure. What ways have you tried to erect structures on your land or for temporary purposes like Burning Man?
