This is the South Wall

This is the West Wall

This is the East Wall

and the North Wall

One of the plus things about having the 5′ clearance for the rolloff is that I can build 5′ shelves on 3 of the wall.
I wired in 6 plugs 2 on each S,W,N walls can’t have to many plugs!
I have LOTS of work space.
