Got the roof beams up just in time before the sun set. They went up pretty quick and was pretty easy to do by myself as the joist hangers were already attached to the hub, I could just slide the beams in place and then climb up on the ladder and screw them in.

Finished the first layer of cob on the exterior of my structure. I think It has gotten too cold here to work on the interior for risk of freezing and cracking. Looks like I could be waiting until spring for completion.
