Just came across this app in the google web store.

It's a 2D/3D home floor planner that I can see being very easy to convert to GM usage.  I've only played around with it for a few minutes, but basic floor plans are easy to create and with the toggle of a button you can convert it to 3D isometric view.  The best part is that you can print either view or save it as a pdf file.

I've used http://floorplanner.com  to make a couple indoor maps, but your looks better. Will give it a try for my next run (Break into a DocWagon clinic to kill someone in intensive care.)
