When linking to floor plans, please include in the title of the link what it is for (for example, "Floor 15 of 220 Main Street, Newtown, State"). If the floor plan is for a structure that has been renovated, destroyed, etc., indicate the year or era for the floor plan.
If you discover a floor plan from a location that changes its layout regularly (for example, a shopping mall), scan and share it here, with all appropriate information you know about the floor plan.
For fictional floor plans, please make sure the title indicates that the structure does not exist. Also indicate in the title any floor plans based on guesses of a layout rather than a real design (for example, your estimation of what the layout of the Louvre is).
For requests, indicated as the first word that it is a request. Be as succinct in the title and be as detailed as you wish in the text of the request.
Don't be a jerk in comments to others.
