Emergency Shelter-Long & Short Time Stay

i finished the first floor of the recreated building, the original building, i built for an Autodesk competition and won runners-up, now I’m making a 3d model of it again, this time in PLA. The rooms on the first floor are as followed: children’s area, front entrance room (chill and relax), library, computer lab, cafeteria, 1 male bathroom, 1 female bathroom, and elevators. The building is supposed to be a shelter in the case of an emergency of any sort, like natural disasters or shootings.
