During the three year period 1990-1992, the research activity carried out in the Typological Laboratory has been focused on two specific themes: flexibility and typological innovation in dwelling-areas and features of the bathroom for disabled users. These themes reflect two among the chief subjects calling the attention of the Residential Building Committee of the Ministry of Public Works to which - as everybody knows - the Laboratory is subordinated. Both themes have been approached through specific application pro rams which took as reference points, respectively, the Programm of EUROPAN Competitions and the proposals for bringing up to date.
