The boost in social housing interventions is the answer to the growing demand for new housing caused by higher social vulnerability in the wake of the economic and financial crisis in Europe. It meets the goal of inclusive growth, as defined in Europe 2020’s growth strategy. This paper deals with this issue starting from an analysis of the social events that are worsening the housing problem in Europe, and which are exasperated by the anti-crisis measures implemented by the Governments of the most financially stricken countries. This paper then highlights the key role played by social managers as the element that guarantees intervention sustainability. The case-study of the Fondazione Housing Sociale demonstrates how the social manager is a key element in social housing interventions.
