At the interface between the urban structures of Basel and the village structures of Allschwil, the large-volume ensemble of the Bachgraben site raises the question of the appropriate type of open space and its relationship to the surroundings. Instead of small-scale garden images of the agglomeration, the reference space lies in the surrounding landscape.
