Along the E314 motorway, a 12-metre high unit in Aluminium. The front wall in structural glazing. Uminescent lighting in alternating colours attracts the attention of anyone driving by the building at night. The existing office building is being expanded. The expansion consists of a volume composed of three storeys whereby the technical volume of the existing building is being included within the new volume. The ground floor consists of a reception, sanitary facilities and a storeroom. Floor +2 has an office function linked to a multifunctional space. In this open-space office, a warm patio has been planned to create a pleasant working climate. The multifunctional space / lunchroom leads into a large terrace. With regards to materialisation, it has been decided to maintain the unity with the existing office. This is revealed in a plinth across 2 storeys in corrugated aluminium sheets upon which a glass box is placed.
