A few notes:
-This is the best I could do. I'm sure there are errors, but hopefully nothing catastrophic.s
-The bathrooms don't have toilets. I hate drawing toilets and I was too lazy to find one to stick in
-Layers are already setup. The construction layer has the full foyer circle in case you want play with it
-I made this with my home version, which prints the "Created with an Autodesk Educational Product" on the borders.
Good Luck!
