In 1998, Wirtz International won the competition for the new Law Courts in Antwerp in collaboration with Richard Rogers, Arup and Van Veldhove Engineering. The gardens consist of 4 spaces between the wings of the building, of the exterior perimeter around the building and of the Bolivar Square in front of the Law Courts. The four gardens between the different wings have a fluid structure of waivy beech hedges (Fagus sylvatica) opening towards the landscape. Different types of trees support the architecture of the building and lead to an interesting confrontation between nature and architecture.

The exterior limit of the project is designed as a strong break, inspired on the shape of a Vauban fortress. The Bolivar Square is an important new public square where people can meet. A grid of 98 table top trees (Platanus acerifolia) gives support to the building. Coming out of the Law Courts, standing at the top of the main central staircase, you will look on to a roof of leaves, with taxis and trams circulating below.
