Our proposal explores the opportunities of re-using the old waterways that formed the backbone of regional commerce in the past. “City Ports” are proposed as transfer hubs strategically positioned in between the massive logistic landscape of the port of Rotterdam and future cities where clean industries and housing could co-exist once again. This proposal thus establishes a regional basis for an urban and architectural task that seeks to gain control over the proliferation of business parks and to reintegrate parts of the peripheral economy into the urban environment.
