How do you bring your first placemaking interventions to the next level, increasing their long-term spatial impact? You can start doing this as soon as your first engagement and collective decision-making, execution and investment power are built in the area and you as an initiator have claimed a certain trust and license to operate. How do you design low-threshold interventions that reflect the different stakeholder interests and urgencies and that also have a scope and scale that reflect the long-term future goals and ambitions? How do you realise your long-term vision for the area by step by step prototyping it and building on each other’s actions? We first discuss a few theoretical principles and then give you a very practical illustration of how this was done in our Amsterdam field lab.
