New building Grüningen

Innovative replacement building for old “Schopf”

Stable construction with Protektor lightweight steel construction

For the new guest house with a floor plan of 8.20 x 6.20 m and room heights of 4.00 m and 3.35 m, the entire construction in the lounge area, kitchen, shower and WC was built in skeleton construction. The only exceptions were the new floor slab and a concrete retaining wall (subject to earth pressure due to the slope). The 6.20 m long and approx. 2.40 m high concrete wall, insulated on the outside with XPS, forms the secure closure. The load-bearing walls were constructed with C-beam wall profiles 97-50-20. High-quality, sustainable products were also used for the insulation, the interior cladding and the façade finish.

C-beam profiles 147-50-20 (wide-span beams) were used for the two opposing mono-pitch roofs, which were freely tensioned “back to back” over a length of 4.20 m in the guest area. C-beam profiles 147-50-20 were also used for the load-bearing suspended ceiling, which was installed for acoustic reasons.
The covered outdoor space measuring 4.20 x 4.50 m with a beautiful view over the medieval town of Grüningen is very practical.

Protektor and the engineers at mar+dietschweiler ag provided proof of sufficient wind, snow and impact load and earthquake resistance.

Conclusion for the building owner

Thanks to the choice of materials and the type of construction, as well as the usual drying times, a cozy guest house was built in approx. 5 weeks. With lightweight elements, low component thicknesses and fast, weather-independent assembly, Protektor’s lightweight steel construction is an alternative to conventional solid and prefabricated construction methods.

Franz Reinhardt AG, a plastering business based in Grüt that has been in existence since 1993, covers a broad spectrum, from drywall construction to interior design, stucco work and plastering and façade work.

By building the guest house, Patrick Reinhardt expanded his experience in load-bearing drywall construction and quickly realized that the use of load-bearing lightweight steel construction can open up new possibilities for plasterers.
