I had posted some ideas a while back so I thought I'd post an update of my little oehler / wofati inspired structure.
It's been a slow-going spare time project, and tons of fun. The biggest challenge has been working with the big heavy logs... first collecting them and hauling them up the hill, and then lifting them in place. No heavy equipment used. You will see my makeshift greek crane in a couple of the pictures, which was a great solution suggested by a permies member on these forums.
Hopefully will have something more complete by the end of the summer
