Floor plan of a bungalow with 140 sqm - does the storage space fit?

Ok, understood! As we wrote in the initial post, we already have the building permit. Therefore the question is how to deal with it.

Yes, then there are two options - be clear about which one you want to choose: either don't touch it anymore, so that (almost) all suggestions are ignored (for my latest words this means leaving the fantasy dimensions as they are and setting the inspector to "extra sharp"), and practically only implement the note about the changed door hinge, or to still incorporate several suggestions and submit a correction for approval and have a small part of the process "run through again". It is always a pity when you ask so late. There have been quite a few constructive suggestions that were sacrificed on the anxious way.

Yes, we first obtained an offer from our house construction company for the roof truss as an attic. This would create an area of about 15 sqm. 10 m in length and 4.8 m in width, I will upload pictures shortly. Costs are 5150 euros plus 220 euros for the modification of the plans. We are still considering. The building application does not have to be changed for this, but how would it look with the door relocation?

Regarding the other option from 11ant, we will have to rely on strict control during the shell construction phase. So far, we have waited 10 months to start construction and want and have to begin.

Picture of the architect is attached.

I calculate almost 50 sqm... plenty of space..

What costs are you talking about? The shifting of the front door only requires a correction to the building application. That is more or less a formality: the fundamental reviews and their results do not change because of this.

Those would be the costs for the attic. Currently, we have a non-convertible attic and thus, of course, less storage space.
