Bashing mostly complete

I filled in the original door opening with sheets of balsa and basswood since I had it on hand. I've put in a spare piece of foam for the front floor until I get the cut pieces of 3/8" plywood back from my parents (they have better power tools).

I cut the new door opening on the other side and made the removable bathroom wall from 1/4" plywood. I glued in the plugs on the back wall and filled in the remaining loft support notch.

Next, I need to plan the deck so I can buy a piece of wood for the landscape base.
