With six widths to choose from, the freedom to apply your own finish, as well as the reassurance of great looking wood Southill is the perfect starting point for anyone looking for an unfinished oak plank. We used the best quality nature grade European oak we could find to make these engineered boards. Nature grade oak includes a broad range of natural characteristics, such as knots, sap and colour variation. All Southill planks are FSC certified so you can be sure they are sustainably sourced . Choose from skinny 100mm planks through to superwide 300mm boards, 15 or 20mm thick boards and square shoulder or microbevelled edge details. Each plank has been carefully sanded to achieve a sleek, uniform look. Southill is suitable for use with underfloor heating systems and 15mm options can also be used as wall cladding. Use any of our custom finishes with this floor depending on the gloss level and durability required. You can get details of all our finishes here.
