A vacant former school building in Hillesluis, Rotterdam-South, is transformed into dwellings specifically designed for residents of this area who are moving upward the ladder of social mobility (“sociale stijgers”). In order to enable them to climb up (or start on) the property ladder, research is conducted on their housing preferences. Three different public functions (social, cultural and for local businesses) are added to the programme, which results in a mixed-use building designed for the residents of the neighbourhood.
