A seven-year long follow-up of a self-planned housing community of 21 families at the outskirts of Helsinki has made it possible to explore the meaning and role of the physical environment in the intrapsychic work of the individuals, in the family dynamics and in the everyday life of the small housing community itself. The results show that there are striking differences in the temporal, spatial and psychosocial dialectics, constantly present in the individual transactions as well as in those of the families. These are due to personal, gender and sociocultural factors influencing the creation, use and expression of a idiosynchronic code system.
