I don't know what AlJay2000 's real opinion is, but we've been fairly relaxed in the past. I've often changed the location of doors or windows or re-interpreted the use of rooms that have labels (made a "bedroom" into a kitchen for example), and occasionally have made minor changes to a room's shape because something just wasn't working for me, or added a basement or a shed or something, and I never pay attention to where furniture is placed in a blueprint at all if it shows stuff like that. And they've never kicked me out. 😁 A lot of the fun is trying to work with the existing floor plan and seeing what others do with the same design, though, so I try not to make any drastic changes.
