Rock of ages
I know the idea of building for posterity is probably on the back burner seeing as we’ll all probably be up to our eyeballs in water by the time we hit 2050 and our net zero greenhouse gas commitments, but if ‘eternity’ is on your client’s design tick list you might consider Fiandre Architectural Surfaces’ lovely Alpi Chiaro Venato marble from Italy’s Aosta Valley in the western Alps. Intensely green and illuminated with white veins, its available as part of its Maximum porcelain tiling collection. It’s made of 40% recycled content and apparently got LEED certification – so your two fifths of the way to zero.
