The rare wood of the bog oak and its wide range of natural colours were the inspiration for this parquet flooring and these solid floorboards. Fossilised wood, which is characterised by its high durability, has spent centuries buried in damp areas, submerged under water in moors or in bogs. In this case, it has been imitated using fresh oak that has been artificially aged. The top layer of the floor is shaded grey or black throughout its complete thickness, whereas the natural transition of these colour shades is another property of the bog oak. A finishing with oil or beeswax gives the surface an additional silky shine.
