The ground floor at Osterley Park in Middlesex displays an iconic chequerboard limestone floor, worn over the years by the passage of scullery maids and footmen. Our Osterley porcelain floor tiles authentically replicate this aged look in deep grey black hues have all the practicality and low maintenance of porcelain, and an R11 slip rating for use indoors and out. Suitable for interior and exterior floors and walls.
