The growing need for housing in the Netherlands comes with a new set of challenges for planners and designers on how to design new buildings in a country that already has every square inch planned out and dedicated. This lack of building land naturally leaves us with the question on how to increase the density in the city without overburden its citizens and infrastructures. In this regard the town and city-centers should be given especially careful attention in seeking out potential spaces that plug into the existing infrastructures and building cultures. Filling up vacant lots and adding top stories to existing buildings is a particularly sustainable and non-destructive way of increasing the density in the city. Another way is the refitting or removal of existing building blocks and structures in order to enhance them with structures that offer more space and opportunities for the citizens of the city in question.
