An Alternative to Mass Housing

First translated in English ten years after its original Dutch publication in 1962, this book has inspired practitioners for generations. It’s proposal to distinguish the infill from the support – what users can individually decide in a housing process from what users share – has turned out to be feasible in practice. The Natural Relation – the interaction of people with their immediate environment and the central concept of the book – is the result of that distinction. It is essential to the well-being of everyday environment regardless of function or available resources.
