I recently built a structure with bamboos, inspired by the “Da Vinci bridge” (which is a specific simpler case of a reciprocal frame structure). Bamboos are neat: they grow fast, they are cheap (some people will just be happy if you cut theirs for free), they are quite strong and flexible, they’re relatively immune to rotting, though they’re organic and bio-degradable, but they are not always easy to work with when it comes to dimensioning…
