The world renowned specialist for refrigerant compressors BITZER is developing a new office building in Sindelfingen close to Stuttgart. Both the position of the office tower immediately next to the existing buildings and the height totalling almost 75 metres are a clear sign that the company has accepted the site as its headquarters. The two-storey annex building, an arrangement of superior functions around a central courtyard, including a canteen, kitchen, exhibition and meeting rooms as well as a conference area, is positioned immediately next to the slender tower. The foyer, the hub of the new building, is located at the junction between the tower and annex. The design of the office tower is based on the idea of a vertical campus. The central element is a transparent, full-height zone, which rises from the forecourt and is characterised by a network of single and multi-storey communication zones. The vertical campus is not only a distinct feature in the facade, it also offers employees a differentiated arrangement of space for varied styles of communication in the interior. The 17-storey building, which can be let in different sized units, with an adjoining annex and two underground car parking levels for approximately 340 cars accommodates 500 workplaces.
