This paper presents the relevance and the potentials of self-formed, small-scale architecture for sustainable habitations. Three aspects interact in one integrative approach to achieve a minimized impact on nature concerning the whole life time cycle of buildings: Firstly, the use of regional material only. Second, the philosophy of micro-architecture based on the approach of Richard Horden, and as a third point, self-formation to simplify the assembling process of wooden lightweight structures. Complex site-responsive geometries can be realised out of straight wooden members, which are bent into statically self-interlocking configurations reducing material- and energy-consumption to the maximum.
