Pretty easy to do once you get into it, but lots of headscratching working out the best way to do it if it's you first time. Loads I would have done a little neater on mine, but does the job.

I had upper deck built then did the lower deck myself once I had seen how it was done.

before...



after



looks nice with the little blue LED lights in and chopped and change bits a few times recessing the step and covering a pond we had in the lower deck, so just got to stain it all up. Certainly covered up what was there before!!
