"Developing a new village is a special and complex task. The design must be flexible enough to allow for changes over time, so it is best not to create a binding blueprint but a framework of main outlines instead. At the same time, we need to build more than just physical space, namely a community," says Jeroen Dirckx, partner at KCAP.

In addition, the urban planners of KCAP provide many plots with different sizes but also some plots dedicated to the auto-construction. The goal is to allow architectural diversity and avoid a negative effect.
For the first subarea, the urban planners of KCAP have provided a large proportion of affordable owner-occupied and social rented housing. This Valkenhorst neighborhood will be energy-neutral and nature-inclusive.
