When engineering expertise and digitization know-how meet at the highest level.

Our mission: Digitalization of old real estate, company premises or buildings in the public sector.

STF Swiss is a family-owned engineering company based in Switzerland, which originates from the German STF Group. With over 600 employees at over 20 locations, we are one of the largest engineering services providers in the DACH region.
