For the success of architectural projects in local communities, the involvement of the inhabitants and the integration of their communal knowledge about the needs and living conditions in their neighbourhood in the development process is essential. One of the citizen experts from Rotterdam Noordt is Mitchel Samson, whose expertise lies within “Passion Development” targeting the young residents of the area. By founding the non-profit initiative “Cult North”, he wants to create a safe environment in which young adults can develop their personal potential, talents and self-knowledge. This project supports the vision of the initiative in a spatial context by creating a flexible space that integrates elements of Rotterdam’s street culture and urban materials that can be easily adapted to specific use cases such as participatory events, workshops and seminars.
