We are a subsidiary of Keller Holding AG, which is based in Pfungen (Switzerland). Keller Holding is an independent family business, which has been rooted in the construction industry for several generations. In fact, the company has now been producing bricks at its two brickworks for five generations. The company still makes a wide range of clinker bricks and facing blocks at one of these brickworks and is the only Swiss company left in this production sector. This product range is distributed by Keller Systeme AG and can be viewed at our unique showroom in furnace hall No 2.
