There are hardly any hallways in the building. If there were any they have been expanded to become studying areas for students. The architect choose different floor colours and materials but all with the criteria of sustainability. The colours of the building have the same contrast as the face of the building. They have two colours, one goes from red/orange to purple and one from light green to turquois. The constant factor are the combinations in colour. Even the wood and the turquois floors fit the design. KOLEN delivered and placed 2,400 m2 ceramics for the floors and the face of the building.
