Hi, first post here and looking for some advice please. I am planning a small area of decking 8'x6' and was thinking of using cls timber for frame ( treated with cuprinol wood preserver ). One end wil be resting on paving slabs the other raised about 1' to get a level. I am going to bolt cls legs every 2' to get the level. cls joist at 18" centres +noggins, wickes decking on top. Any pitfalls. Using cls is to keep cost down as much as poss skint as usuall. Thank you for any help or advice. All the best
