The trapdoor in the rec room is also finished. That was a genius idea my brother had. It allows access to the room, without people potentially falling to their deaths and without railings blocking a good chunk of the room. The silvery bit in the far left-hand corner is a “metal” groove for the owners to grab into to pull up the door from the inside. I didn’t want a knob on the floor side, as I thought it would be easy to trip over. These are the little hinges I used, which worked perfectly.
