Geheimwaffe Wohnen evolved from an experimental approach on the relation of human interaction. Therefore objects of daily use were ripped off of the natural habitat to get an inside of how we interact in space and what we use for hacking our spaces. A canvas, a window ledge, a clothes line and a perch were extracted out of their relations. With the deeper meaning of the interacteral relation between human and space, new paths of living together were conquered. The alpha-space is the retrospectative & deconstructed sense of a human made space. The beginning of a space is disorder. Through continuous interaction it transforms into a place of whatever you want it to be. As follows the source-space maintains the full range of spatial allocation in order to represent itself as the widest interactional space for citizens. In a canton of BASEL an extended version of the micro experimental housing project is imagined on a backyard site with onelevel garages for individual transportation. The concept envisages seeing the alpha-space as the starting point for human interaction in space & depicting it in the spatial sequence of already defined spaces. This thought further leads to the fact that a spatial calibration is subliminally initiated by every threshold that announces a change of space.
