this is not a construction stop. A construction stop is imposed by the office, the authority, and is a sovereign measure.
There was no talk of a building suspension order here. Only one contractual partner has declared that they will withhold their services until clarification. A merchant, aware of the liability for damages that would then arise, will not do this without reason or justifiably. Based on experience, I therefore also consider the suspicions already expressed here of a provocation by the original poster not to be unfounded. A "typical" cause would be, for example, that after disagreements over the contractual provision of services, the client feels justified in violating the next step of the payment schedule in order to force the other party to accept his opinion. For example, because now a ventilation duct or downpipe is boxed in where the client had dreamed of a very specific cabinet model. He sends this via WhatsApp to the site manager, the site manager refuses the dismantling, the client stops his payments. Any resemblance to reality is, of course, purely coincidental ;-).
Until a house builder – if they are not a butcher, *LOL* – has had enough, something usually "has happened."
