This actually makes me smile; especially the part where the contractor showed up early for once, just when you had plans to relax!
It always seems to happen that way, doesn’t it? I’ve never built a patio either, but I can imagine it’s the kind of job that feels tough in the moment but really satisfying once you start seeing progress. The “stone wood” sounds intriguing; low maintenance is definitely a plus! I don't know the equivalent of the stone words in the part of the world, though. I hope the second half goes smoothly next year, and the weather doesn’t throw too many surprises your way.
