Proposed building here is the clinic. It is small and does not use green baseplate, at least in the presentation on the back of the packaging.
Upper view
Version presented here is extended. I have used green base plate and constructed additional buildings for guard and storage of medical resources. The car is no longer an ambulance, it is a delivery car.
Treating
Inside the building there is not much space. It is enough to treat the patient with minor injuries though.
