XS is taken literally. Thus, the individual rooms such as bedroom, dining room, kitchen, etc. are reduced to a minimum of 2.66m x 1.16m or 2.16m. These individual rooms are located on a mobile pedestal, can be moved by two people and drive on the rails with a train system. Four individual rooms complement each other to form a group ("cluster") and can thus form a house - but also stand alone. Thus, the requirement for a changing number of users (couples, families and groups). This concept can be understood as an experiment for urban living, which requires changed spatial structures due to demographic change and changed living concepts. For example, it would be possible to "switch on" different rooms, to divide and to "push off" again when they are no longer needed. So not only varies the number of sleeping options, but the guest in the holiday village can also book additional comfort such as sauna, library or cinema on a daily basis. The result is a flexible "breathing" structure.
