ABK with the Sensi 900 tile collection celebrates the marble varieties that marked in the architectural contest the emergence of “modern luxury” at the beginning of last century, a style characterised by a restrained and simple elegance in which the focus is on the materials themselves. The Sensi 900 tile collection includes several classic marble varieties such as Bianco Carrara, popular for its sober aesthetics and pure background, Stone Grey, with its sophisticated mud-grey colouring, and Precious Black, an elegant black marble streaked with golden veins.
