If you have 2 weeks of vacation and are woken up every morning by loud rattling, hammering, sawing, and knocking, but can't use your terrace.. Quite annoying.. Especially with the temperatures.. Today 24 degrees, sunny, partly cloudy.. Oh, and tomorrow 31 degrees.. No terrace but hey, everything's great, sitting inside all day at these temperatures
Was the landscape gardener actually put in default? Was there a written complaint about defects? Was a contractual penalty for delay agreed upon in advance? So something like "I had to get up early for nothing today and that is worth 200 € to me" doesn’t work...
: rather wrong, but you can judge everything from a distance
Certainly not, because I have no crystal ball; I rely solely on my experience in dealing with people - also online.
What is the contract for? More like a piece of paper to wipe your bottom with? Or more like a recommendation?
No; a contract is always binding. However, from my point of view, it is not the end of the world that your access road is not finished yet; annoying yes, but nothing more. If your single-family house were not ready to move into yet, that would be far worse; especially regarding double burdens.
I am sure that the threat of a lawyer, which you want to build up, will not be helpful to speed up the completion of the access road. But you will probably harm yourself, since the craftsmen may not be too eager to deal with your access road/terrace.
Therefore, let things be; there will be reasons why your contracting partner is behind schedule. And who knows - if you approach them with a bit more understanding - maybe it will even pay off for you
