This building represents a symbolic forum for the chair-manufacturing company Interstuhl, based in Tieringen-Messstetten. The ground floor forms the communication interface between the company and its customers, suppliers and staff. Customers make their first contact with the company in the fully relaxed atmosphere of the spaciously designed foyer and cafeteria. The theme of this
living and ongoing exhibition continues through to the ‚Conferencing‘ exhibition and training areas situated in the rear of the ground floor. Housing the building’s technical systems the encapsulated nucleus connects the foyer with the company management offices and the exhibition area on the top floor. The core of the company’s presentation is located in the nucleus; this intensively staged room
serves to introduce the exhibition dramaturgy. The top floor consists of a large hall that offers an ideal platform for changing objects. The open ground plan is free from supporting columns to guarantee the greatest possible efficiency of use.

After the construction was completed, WSGreenTechnologies carried out a building certification in accordance with the “New-build Office and Administrative Buildings, Version 2008” system variant of the German Sustainable Building Council (Deutsche Gesellschaft für Nachhaltiges Bauen, DGNB). The “environmental quality”, “economic quality”, “sociocultural and functional quality”, “technical quality”, “process quality” and “site quality” were evaluated during the assessment. All evidence required for certification was prepared or its provision was coordinated before subsequently being assessed. Werner Sobek also calculated the Life-Cycle Costs (LCC) and generated both a Life-Cycle Assessment (LCA) and a Recycling Concept. After the certification documents had been examined by the DGNB, the project was awarded a DGNB Certificate in Gold.
