Are there any good resources for finding old floorplans? We have, I think, a dutch colonial revival sorta something, supposedly built sometime in the 1920s, turned sideways for a narrow Chicago lot. I tried some historical research through Chicago sites, but didn't find much. I plan to ask the neighbors at some point, but as they moved in in the mid 60s, can't be sure about any changes there either.
I'd love to know our original floorplan. Also, is there any easy way to figure if a wall is structural, or is an engineer the only way? We're not planning on ripping out any walls, just kinda dreaming/planning.
