Hi @mattphilleo, thanks. The bridge is quite solid, I'm just worried a little about having forgotten to put nice big stones that will drive water away from the trunks touching the sides!
Well I would live to build a house in this way, I live in New York state where regularions are coocoo! But there are plenty of loop holes to exploit.... tree house, something on wheels, no regulations on shipping containers, hunters cabin... or try and get permits for a house in a Sun Ray Kelly style!
We will see...
