I have a patio where there are currently stone slabs. Roughly 7x2 meters. Here, I am planning to build a deck/wooden terrace instead.
I have lifted a couple of slabs and seen that there is about a 25cm layer of sand under the slabs. Under the sand, there seems to be a lot of blasted rock.
The slabs are level with the patio door, and I would like to have the wooden deck at the same level.
I have some different thoughts on how it should be done. How would you do it? Dug down posts to build the frame with, or are there other smart tips?
