Absolutely fascinating. I actually recently made a Thomasson myself. My condo had a second door in the kitchen that exited out to the exact same hallway my main door does, just about 20 feet further down. When I renovated my kitchen, I removed the handle, permanently fixed the deadbolt into place, drilled the door shut into the frame, then drywalled over it on my side and put a wall of cabinetry and my fridge in that space. So now from the hallway there is a completely unopenable door that doesn't even have a handle, and from the inside of the condo, you wouldn't even know the door was there.
