Housing, looked at from a communicational perspective, shows a peculiar characteristic: it is an environment, a situs of communication and at another level it is a medium, a vehicle of communication. By themselves each of these two dimensions leads to certain questions; but through their combination a new quality arises and we are challenged to cope with the problem of reflexivity. In this paper I propose a research framework for the study of this double-faced feature of the home. A case study shall help to illustrate the points and to sharpen the instrument.
