Love it. Wanted pretty much the same but haven't got the space. Ordered a shed instead and having them install it for me, no longer up to it myself
Only getting a 10' x 8' Apex but will insulate, board and fit electrics and workbenches myself. The whole project is just to get me out of the house and hopefully pursuing new hobbies. The mill with an integrated laser and a 3d printer are on my shopping list.
I really like that bench and would like something similar. If I were to pick a fault with your build it would have to be the T&E clipped to the walls. A nice white plastic conduit would have looked better. Small point though, still love it.
