Day 3 Stuttgart - Basel
Leaving Stuttgart, we will visit many green roofs in transit to Basel (Switzerland). For example, a zero-impact housing development will illustrate the integration of green roofs into sustainable design. 
Scharnhauser Park is considered a model for ecological building design.
