The urban integration of a site is defined by the treatment of its corners: the corner has a relation with a number of public functions along a main road. This explains the implantation of the new building. The building is well-orientated and has a favourable compactness-economy-energybalance. The acoustic comfort is guaranteed by the patios that separates the offices. The parking is digged out in a slope - the thus minimized amount of removed polluted ground is used to create an artificial landscape garden with fytoremediating plants.
