In August of 2016 the new detention centre JC Zaanstad was opened. The facility is designed to host over 1.000 inmates, including 125 persons in a penitentiary psychiatric centre. Most of the 676 cells are a multi-user type cell. The detention centre is the largest and most modern in the Netherlands. Fokkema & Partners designed a robust interior which radiates calmness and overview. Self-reliance and responsibility for detainees, resulted in a design that integrates the latest technical possibilities and ICT. Security aspects are integrated and are not dominant in appearance. Easy orientation within the building is achieved with thanks to careful planning. The overview from the monitoring stations is maximized.
