I have built a couple of them over the years.

I did one in our last place. I used two layers of MDF and got nasty......The first layer was screwed to the studs AND dwangs, and the secod layer was glued on over those scres and bolted through with coach bolts and I put a pin in each of the bolts after the nut so it would spin before undoing if they got the coach head to move....It looked like the coach screws held it on but they were simply there to frustrate anyone who bothered to undo them. I then mounted heaps of shelves to the outside of them to further frustrate anyone trying to access via the wall. Then the door was located between two steel 100x50 studs and opened inwards so if they tried to kick it in the locks would have to pass through the door as the Jam / frame would not give.

..I also put 15mm holes in the studs and threaded 12mm reinforcing bar through them. The bars would spin if someone tried to saw through the wall. Parallel to that were the power cables fr the 3 pin sockets (fans and tools etc inside the room) and lights. These were "protected by the steel rio bars so they would not get cut, but if said crim accidentally cut one while trying to break in, it would have been unfortunate.....
