Practice partner David Nelson said it was a 'rare privilege' to complete the design for 'Eurogate', as it was part of a masterplan that had been in progress for 'more than a decade'.
He said: 'It is a distillation of our original ambition to create a sustainable, vibrant waterside development.'
The Duisburg Inner Harbour Development Company commissioned Foster and Partners to work on the masterplan in 1991.
It also includes designs for cafés, restaurants, an art gallery, houses, offices, converted historic buildings and a new park.
According to the architect, the landmark ( pictured) is punctuated with courtyards and atria to ensure natural ventilation.
At ground level, the design includes plans for cafés, a promenade and steps abutting the water.
