Timbers and joinery methods Using either West Australian Jarrah for indoor/ outdoor use or Victorian Ash for just indoor use. All our furniture is constructed in the tried and proven traditional methods of mortice and tenon joinery to withstand rigorous traffic in commercial and public places. Indoor and outdoor finishes We use only the highest quality timbers. Our furniture is then oiled for outdoor use or polished with two pack lacquers, which is easily maintained and highly durable for indoor use.
