Common Ground is a building that will facilitate space for people with different interests. These interests can vary, from wanting to know more about earth as a material to searching for connection with new people. There is one common ground with the functions and users of the building. Earth is the connecting subject. These are the functions for now: leisure, workshops, a library, a laboratory, production space, storage, a rest place and expositions. This can change when there are different needs. These needs could be affected, for example, by the weather, time, social problems or how much we know about earth.
