Ah composite decking. We were going to re do our decking in composite. But 30m2 of it raised up 0.5-2.5m turned out to be rather pricey. We did the small raised bit for our arbour and steps up to the shed (yes jon I do actually have a shed). The rest will be done in timber, probably next year now as the planning application for our extra loft conversion is being considered by the planners.
