Societies are usually built up like spatial/social tree structures. But some links are missing here between the scale level of the neighborhood and the individual house. Streets can do the job, but are not fit for it, because the scale is too big and the social meaning is ignored. In the essay I want to show how the gap between the neighborhood and the individual house can be filled with spatial scale levels that have a social meaning. An approach in which different kinds of cohousing can emerge, an approach in which future inhabitants can have an emancipated role in the design process.
