@janklabs: I'm building the second floor on the shack addition today. there was some mistakes and regrets along the way in the way I built it but it still turned out all right. it just took me a little longer and was a little harder than I expected it to be. but now I have a second floor loft where I can put my bed. and the framing is pretty much done for the house. now all I'll have to do is put on the roof and then I can start working on the interior
