:ZCCS has developed a transversal approach towards the city and its components. Grouping together architects, landscapers, and urban planners, they operate for urban and landscaping studies, as prime contractors for urban and public spaces works. By their attraction for the territories of ports and quays in the city; the city-port relationship; the transformation of port wastelands or the "humanisation"; of these sectors of living and of the city are at the centre of their concerns. Their mutation or their restructuring upset the relationships between the spaces and men and redesign a new port or waterside culture. ZCCS has set as their objectives the accompaniment of the transformation of these territories in order to turn them into desirable, lasting and sustainable places.
