This paper is a continuation of the paper entitled “Collaborative Housing Perspectives in Poland. Definition, Historical Overview and Examples” and it describes the possibilities of implementation of collaborative housing in Polish conditions. In the paper, apart from legal constraints, the author also describes the benefits of collaborative housing, because as far as benefits of building homes in the construction group system, co-operative or co-housing seem to be quite well diagnosed for the inhabitants, the benefits for the city – which, based on the author’s studies, are huge – are not described well enough.
