The European Central Bank broke ground for its new twin-towered headquarters in Frankfurt, Germany.
Costing in excess of €850m ($1bn) the 44-storey ECB headquarters will be complete in 2013, according to AFP.
The design features two towers of 185m and 165m (607ft and 541ft) linked by an atrium and interchange platforms.
The project will also involve revitalisation of the adjacent neighbourhood, for example, the glass-clad buildings will integrate the nearby landmark market by converting it into a visitor and media centre.
Wolf Prix is the head architect for the project.
The sustainable scheme will employ energy and water-efficient strategies such as natural ventilation and geo-thermal heating.
