No construction company found that...

logical, contact has already been made. But anyone who wants to build a house should not only seek advice from one company. Instead, they should choose the best one for themselves. If someone in the construction industry does their job well, they do not need to fear their own offer

I find it funny that no company is supposed to be willing to use KS instead of PB? When we negotiated with the companies, the KS option was also an option for us. We gave it up because we have a plaster facade and due to the insulating properties of PB. But 4 out of 5 companies said, no problem, you can have KS as well..

Of course, if you go to a company like He...ma or Vie..ock, who push through their standards and the schedule simply does not allow deviations, that's something else. Or directly to the architect, who will also build you a house out of wood...

How many companies did you contact?
