This strikingly beautiful range is reminiscent of 18th century stone floors, which were originally made of various materials, including shells and fossils. We have replicated these typical details, and given the tiles a contemporary twist by including concrete and Jerusalem Stone without losing the old, worn look with its soft undulating surface. This Alnwick flagstone has swirling grey tones, and comes in either a natural or semi-polished (honed) finish.

Due to the variation which occurs with ceramic, porcelain, decorative & glazed tiles in each handmade batch, we do not accept returns of surplus tiles. We recommend measuring your space accurately before ordering and keeping any spare tiles as they can be utilised should any damage occur after the tiles have been installed.
