The Housing Transformation Process: Case Study of Government-built Housing in the Philippines

This session introduces the process of housing transformations. It aims at understanding the implications and constraints posed by social housing projects in providing shelter to low-income groups, without a clear understanding of people’s housing needs.


The case study presented allows us to understand people’s spatial, socio-economic, cultural and livelihoods’ needs in housing. It provides valuable insights on how to adequately meet the needs of low-income households by looking at the different factors that trigger the decision of a household to transform its dwelling, and its desire for a liveable neighborhood.
