**Building Construction Basics**
There are two basic type of building that can be built, Terrain buildings and City buildings.
Terrain building are buildings that require some sort of terrain resource like forests for a lumber mill or just space for a farm. City buildings are buildings that don’t take up map space and mostly modify other buildings or the general city itself, IE a church or a bakery. When you build a building the costs don’t just cover the actual building it also covers any tool costs or such things. materials to build a building are in units (basically to simply things and make my life easier) be they wood stone or whatever. if a building is not staffed completely but has more then half the needed workforce it works as a building one grade lower. (a large farm only produces 80 food instead of 160).
Construction Units(abbreviated as CU from here out) is the amount of work one untrained laborer can do in one day. (changed the name to avoid the confusion we where making between the man-hours/man-days issue. and it sounds a lot better the man-days)
