Foster's long-standing connection with the city dates back to the late 1980s when he was asked to produce plans to reinvigorate former industrial areas.
Foster's new proposals aim to accelerate Duisburg's 'transformation into a vibrant, green and sustainable city' as well as making the city a more competitive shopping destination.
Among the key features of the masterplan are plans to extend the central retail area along the Königstrasse spine and connect it to a revamped central railway station and interchange.
Describing the project Foster said: 'The inner-city Duisburg masterplan builds on the success of our Inner Harbour redevelopment and continues the transformation of Duisburg into a sustainable city for the 21st century.
'Our ambition is to strengthen Duisburg's civic identity by utilising its infrastructure and promoting the denser use of its centre, creating a modern city that has a rich mixture of cultural, commercial and residential activity at its heart.'
