While open spaces are becoming increasingly scarce, we continue to overlook the possibilities of what has already been built. With this book, RE-ST puts the needless growth of the existing patrimony on the agenda. moreThey define “wanderspace” as built and unbuilt space that we produce together, and yet underutilise on a daily basis. Space that is present everywhere and nowhere on different scales. The task of detecting, mapping, and activating it is an opportunity for architects. The research project “Wanderspace” was awarded the BWMSTR Label in 2018. RE-ST is a Flemish architecture and research firm that looks for solutions to urgent and complex spatial issues.
