On the Rijnhavenkade in Rotterdam, Meelfabriek CO-OP is on the eve of a transformation. Just before the start of this radical development, the current form of the iconic industrial building was documented and its extraordinary genesis recorded. Based on an architectural, urban planning and cultural history study by Crimson Historians & Urbanists, Flour Factory CO-OP recounts the construction, history of use and function of this industrial heritage. The book highlights the spatial historical context of Katendrecht, the creation of the flour factory, the demise of the cooperative movement, the parties that were active in the building afterwards and the complex functioning of the flour factory in relation to the architecture of the building. In addition to a brief biography of the architect, state architect and urban planner J.J.M. Vegter, contemporary descriptions and witness accounts from Rotterdam residents are included. Supplemented by an extensive visual essay by photographer Sebastian van Damme, this book documents a national monument at an important turning point.
