: what do you mean by the consequences?
The cheaper the provider, the more you have to do or organize on the construction yourself. That’s not something everyone is comfortable with. I practically took over the entire construction management, coordinated and supervised the craftsmen (within my professional limits). Well, I didn’t have to do that, but it saved us about a month of construction time.
Then there’s the stress with the connections. We were responsible for that. With Viebrockhaus, for example, the company handles that.
Groundwork, garage, exterior work, etc. were all our problem. In other words, cheap providers lack in service. As a father of two, that can quickly become an impossible task.
It’s also about the costs. These are all additional costs that are hard to keep track of at the beginning. Towards the end, we really had to scramble.
