Terracotta Scuro
An archetypal material
Terracotta collection inspiration is self explanatory. The most ancient ceramic material is terracotta with its characteristic reddish hue and porous consistency.
It has been used since the dawn of time in all civilisations and continues to find contemporary applications.
Nexion selected a type of terracotta widely used in Italy for the construction of its world-renowned old towns, recreating the colour tones and surface finishes down to the smallest details, with three appealing colour options offering different levels of light.
The result is a collection that offers the unique personality of an archetypal material with a contemporary language and excellent technical qualities (strength and longevity), making it ideal for complex and challenging architectural projects.
