The law offices of Van Doorne are located at the “Zuidas” in Amsterdam. The building is spatially interesting because of three open roofs, which in the interior concept of OIII each received an own identity. These differing identities stem from both the architecture and the programme, as well as from concepts that give visualisation to the image of Van Doorne. The unique atmospheres of the open roofs permeate into the surrounding office floors. The lay out of the wings moves through a succession of open to closed work areas and a central zone with general facilities. The colours of the exterior has been continued into the interior design in a refined, varied manner.
