You have to determine the size.
We have 45 sqm and it is almost too small.
At my parents' place in 2013, we installed anthracite-colored terrace slabs from FCN. Mineral mixture, gravel, the outer row in concrete. No lawn edging. Faded in the first summer, unchanged since then.
No frost damage.
We installed wood look from FCN. We have already been asked where we bought the weathered wood.
We were advised against WPC. Everyone who has it is dissatisfied. Some replaced their cheap hollow profiles after last summer, one has solid for over 100 euros/sqm and they turn green.
