Destillery in Finland made with colored concrete with bayferrox pigments

In the construction of the Finnish Kyrö Distillery Company, the architectural office, Avanto Architects, succeeded in creating a unique design. From the outside, the production and storage hall is barely visible; all you see is a large old woodshed. What looks like decades-old, charred wood is actually deep black reinforced concrete, colored with special pigments from LANXESS.

With our Bayferrox® iron oxide pigments, concrete can be colored all the way through so that no paint is needed. The unusual facade of the distilleries was created with the support of our technicians, because we are also a proven specialist in the coloration of concrete. 

The interesting wood look was created by an elaborate concrete casting process in which old boards from a dismantled barn were removed and served as a template profile for the concrete blocks. The result was, deceptively realistic, the most modern "wooden hut" in the Finnish forests.
