Piston Ground Door

A piston door design I plan on using in survival on a large underground complex.

Has 1 locking mechanism so you can lock the door in place (either open or closed) from the inside. This prevents mobs or players from using the switches on the outside while you're in your base. It only cuts power from the outside switch so even with the lock on, you can open and close the door from the inside. I added a redstone lamp to act as a locking signal. When on the lock is on, when off, the lock is off.

I color coded the wiring and lined the stairs with glass so you could see inside.

Blue: T Flip-Flop
Red: Door Power
Gray: Outside switch
Orange: Inside Switch
Green: Locking Mechanism

Ideally, the top glass above the door would be grass or some other natural block to kind of conceal the entrance and the gold door replaced with something less noticeable.

I tried to make it as compact as I could. I believe this is small as it can get in it's current form. Maybe you guys can download it and prove me wrong! I'd love to see more compact versions or anything you make from this.
