We made it to the stage where we start putting up walls! For the kitchen area Shawn used reclaimed pallet wood. It turned out really nice and it is starting to look like a real Skoolie.
In the bathroom we did regular plywood and put in a small counter top for the sink and to hold a small amount of toiletries. I used cement board in the shower room and installed a little bench since the head room is kind of tight.
In the back bedroom we used a thin sheet of veneer type material. The pattern on it looks really nice so I am happy with the way it turned out. I used regular OSB ply for the top of the bed and installed a bed lift kit so we can still get to the storage underneath.
