The constant growth of the successful family business Sigmatek – specialists in automation technology for makers of industrial machines and plant – has resulted in the third expansion phase of their factory location in Lamprechtshausen. This involved adding an extra storey to the office tract and for this project they chose Kielsteg, firstly to minimize the additional load on the foundations. But also, thanks to the wide clear spans of the Kielsteg construction, the new office space has hardly any internal supports. This allows the company to use the space as flexibly as possible, which serves their corporate strategy. The roof was built from Zenz Timberconstruction from Eggelsberg with high-performance KSE 800 elements, which span the whole width of the building of 25.4 m. The underside of the elements is visible and forms part of the interior design.
