| Summary: | This paper starts from the hypothesis that streetscapes with shorter façade lengths are more pleasant for pedestrians than long and monotonous façades. It analyses four case studies where short façade lengths were implemented by applying different means of regulation and gives insight into an experimental planning example from Schlieren, Switzerland. Through the investigation of these cases, different possibilities to regulate façade length were revealed and categorised. The applied comparative case study analysis and comparative approach showed that most case studies are project-based solutions, either by applying text-based regulations or by reducing parcel size. The experiment in Schlieren offered a possibility to reduce façade length to a maximum value within the standard building regulations (Rahmennutzungsplanung) and therefore make it applicable to more than just singular projects. This approach failed, since it falls into the category of form-based codes, which in the canton of Zurich are by law not allowed in all zones. The experiment showed, however, that form-based codes can act as a powerful alternative to reduce façade length if parcel size cannot be influenced and more than just one single project perimeter is to be regulated.
