Hello,
Great business relationship...
I always try to understand the arguments of both sides. HOWEVER - to find out already at the beginning and especially
before signing the contract that the hopes regarding the client ./. provider relationship will not be fulfilled, that they are already obviously disturbed, does not, in my view, form a basis for a smooth construction process.
The construction industry is booming, no question; therefore I understand that your provider wants to prioritize other construction projects and do not consider this a empty threat in this context; rather a necessity. On the other hand, I do not understand that you, in such a - still - uncertain contractual relationship, have no time to possibly wait 3-4 months. You will - hopefully - live in the house for many years, so it should not fail because of a later construction start. Clear contractual relationships form the be-all and end-all of a construction project!
Have you requested a personal meeting?
Best regards from the Rhineland
