Yes, there is a hole in the floor, a big one at that. This image is looking up from the first floor into the second. The opening is approximately 4' x 8' and once made room for a conveyor belt which ran from the first floor to the second. On the first floor a square was removed then replaced out of the hard wood floors, which we were told by the previous owners was cut to make room for the conveyor belt motor. The hole is beautiful from downstairs as it lets in natural light in the morning. Everyone has an idea for the hole: fireman's pole, swing, elevator, spiral staircase. The fire safety guys (fire marshalls) aren't having it though. So we're going to plug it up. But it was fun to reveal the opening - and the most amount of work yet, besides tearing down walls.
