OpenLock 5.0 Tudor Floor Spacer Kit

I wanted to make a tavern for D&D, based on the Tudor series of OpenLock tiles, with at least 2 floors that could be superimposed in a single building.

But there was a problem with headroom using the standard height walls, so I have remixed a few bits together to create a half-height "spacer" wall. It can be plugged into the ground floor so that everything can be set up in the bar downstairs while action happens upstairs, saving room on the tabletop for the inevitable "creeping crud" of D&D
