KFW Online Confirmation for Prefabricated House

Good morning,

our financier is currently asking for the KFW online confirmation.
The site manager told us that the survey must take place first, then the architect plans and subsequently, together with the building application, the KFW online confirmation is requested through the engineering office (approx. 10 working days).

The financier says this is nonsense - it can also be applied for beforehand based on details such as volume/area etc. and energy efficiency, e.g. KFW 40.

What is the actual procedure now?! :)

Just ask differently, how do you want to know the volume/area if the architect hasn't even planned yet?

Good question!
From the building consultant / prefabricated house company who created a floor plan with measurements based on our planning, also the area calculation on it, which of course is not 100 percent like from the architect.

The financier is right, leaves beforehand....
