WS3 could be some sort of warehouse or garage with a loft. It is part of a plan or system of buildings and lands, and i will list and describe the parts of that building system, some of them will also be mentioned in other building pages like small buildings. When I talk about WS3 though, i am usually mainly referring only to the main central building, with an assumption that all the other buildings and property(ies) will also be around it to support it.
