Städtebauliche Studie Sulzer Areal, Oberwinterthur, Winterthur, 1999, Planning

Urban fragment in an industrial area

The urban-planning island between the railway lines and the little Eulach stream is characterised by large industrial halls and divided into four parts by the intersecting axes of Sulzerallee and Seenerstrasse. Each is connected to the surrounding areas at one point. This island is to be transformed in the long term. The southern area will mainly continue to be occupied by industry and commerce, while the northwestern area will accommodate services, business and urban housing. The northeastern section will provide space for small businesses and housing for families.

Like the 1859 Cerdàplan for Barcelona, the proposed street spaces will be distinguished by various spatial profiles and contrasting rows of trees. The construction fields will be developed as block-perimeter volumes with uniform eaves heights of 16 metres and inner courtyards, or as public open spaces cleared. At the edges of the island, the construction fields open up towards the surroundings and the greenery of the Eulach stream.
