Quality certificates

SchwörerHaus emphasises outstanding quality, a lot of design options and an appealing design – all with regard to the natural environment and compliance at all times with legal guidelines. We think this is excellent. And we are not the only ones that think so: we have won a number of awards from many trade journals and their readers for the architecture of our houses. These include the major German prize for prefabricated houses, the 'Golden Cube' 2018 in the category "Green Design" with the Schwörer show house in Auggen. Likewise, we have been recognised several times for our future-oriented and sustainable concepts as a pioneer in terms of climate protection and energy efficiency.
