Public urban green space, De-sealed areas


A short description of the NSB

Turbinenplatz is a public city square which was built on a former private estate. After redesign in 2004, it was donated to the city of Zurich. Now it is the largest city square and covers approximately 14.000 m². Due to the gradual withdrawal of the industry, the area became the largest urban development zone in the west part of Zurich. The flooring of the square is mainly made of concrete to remember the industrial site but it also contains some gravel surfaces with several birches and seating elements. The rainwater of the whole area is lead in some planted basins, used for the plantation and then drained away. After the conversion of the old Sulzer Escher Wyss factory esplanade, Turbinenplatz is one of Switzerland’s first big stormwater projects located in the city of Zurich.
