Stahlton Bauteile AG, headquartered in Frick, develops, produces and distributes innovative multifunctional products for the construction industry. Its new headquarters at the entrance to the town has a clear volume that provides a landmark in the anonymous miscellany of this industrial area. This reinforced-concrete structure with an underground floor, a ground floor and five upper floors serves as an office building and dispatch building.
The stacking of building sections produces a fascinating yet clear spatial structure that simultaneously presents delightful views of the valley Fricktal. Workrooms surround central courtyards that face away from noise sources, divide the floors into zones and facilitate floor-to-floor internal communication. The structure, mode of expression and selected materials constitute interpretations of themes that are of central importance to the firm. Here, special themes such as supporting, spanning, joining and stacking are condensed within a striking complex, enveloped by internally developed relief-like cladding made of glass-fibre-reinforced concrete.
The flat slabs have cross-sections that vary according to requirements. Most of these slabs are untensioned. Vertical load transfer occurs via four internal columns, walls by the riser zones and facade columns. Horizontal load transfer occurs via shear walls near the stairwells, riser zones and facade columns. The shear walls are braced on the underground floor. With the exception of the TABS heating, the building services equipment is not installed within the slabs, but in a cavity floor system, separate from the support structure. The facade is a structure made of glass with curtain-wall fibre-reinforced-concrete elements.
