Floor plan multigenerational house conversion old barn

and: do you have enough money, e.g. for dormers? Are they allowed?

Everything is allowed, there are no restrictions regarding the shape of the barn - of course we want to preserve the character. I just fear that dormers will become too expensive.

this picture was taken from the west looking into the barn. You can see one of the two pillars and the side support, which then extends from the floor of the upper floor up to the ceiling.

This is the upper floor? ok... how high is the knee wall?

A little input on that: I think the design is quite good,

Me too... more details later

I only fear that dormers will become too expensive.

You probably won’t get away without 1 or 2 dormers, because... wait, if you have a knee wall on the south side... where can you plan windows on the upper floor???? Am I thinking about this wrong?

All roof supports will be removed and the roof will also be redone. So much for it becoming a bigger project...

I do not see this as necessary and certainly unreasonably expensive; the bigger project probably means a winning lottery ticket. Above all, I do not understand why planning is supposed to be done around supports if the house is being rebuilt at its core.

How high is the southern wall outside?

I do not see this as necessary and certainly excessively expensive; the larger project must probably mean a successful lottery ticket. Above all, I do not understand why planning around supports should take place when the house is essentially being rebuilt from the core.

I cannot answer that off the cuff. The structural engineer said that these supports should remain on the pillar. Due to the wind load coming from the north, these should remain...

Is that the upper floor? ok... how high is the knee wall?

How high is the southern outer wall?

By windows I meant skylights that are installed in the upper floor. Attached is a screenshot of the section. The ceiling height on the ground floor is 285 cm, but outside about 230 cm. At the southern wall or on the ground floor there is therefore a slight slope until you reach the ceiling height of 285.

Note: in this drawing the support (in the upper floor) is not shown.
