Collectief Zakelijk Opdrachtgeverschap is located in IJburg, Netherlands. The CBC wanted to make a building that was elegant and distinctive, yet ‘sturdy, industrial and no-nonsense’. In an attempt to accomplish this, the choice was made to rotate the window frames by approximately 45 degrees and cross these with diaphragm ribs to create a triangular pattern, covering the entire facade. As the diaphragm ribs are set outside of the facade, views of the exterior change depending on the angle from which it is being observed. From inside looking out, an array of shadow lines appear across the window panes. After consulting facade builders ‘Bos brothers’ from Goudriaan, Jatoba wood was chosen for this use, which was given a protective treatment against construction damage, but which will eventually turn grey as the building weathers.
Inside, the entrance hall is designed to sit parallel with the north facade, connecting twenty separate units (five on each floor). The wall between the hall and each of the units is completely transparent to create optimal viewing between the individual areas and to encourage interaction between companies.
