I'm imagining something like the mechanisms at Thomas Jefferson's 
Monticello. When the doors are opened a hidden pulley system could move 
bars - like the trafficators on an olde English car - into the hallways 
around the opening.

Can you upload a photo of the floor doors for us to peruse? Us visual 
learners like photos...
