It was a toss up, but in the end we replaced the old hardwood deck that came with the house. The bearers had rotted away so we were left with a lethal trampoline, which I mitigated with potted plants.
The toss up was won by - more decking (I know) but stone would have been more aggro and the cost went up (just as we were looking) and down (just after we had bought the wood).
So decking is now laid on the most excellent base (DP has AS, so it is absolutely spot on). The question is - what colour grey should I paint it? Pale grey/blue, charcoal? Battleship? Any suggestions please - with photos if possible. Ours is quite large & staggered, so we will be softening with planting and upright driftwood.
