The new Palace of Justice in Antwerp is regarded as one of the architectural high points of Belgium in the 21st century. One hundred exceptional roof-shaped plane trees were planted on the square in front of the building. Van den Berk supplied the trees with a special trunk height of 375 cm, trunk diameter of 30-35 cm and a double roof. The trees were planted in the spring of 2006 and already provide cover with attractive green foliage.
