Single-family house 172 sqm with garage and sauna

I have the feeling that the drip edge point you measured does not fit.

Als Traufpunkt (auch [I]Traufenpunkt) wird ein Schnittpunkt zwischen der senkrechten Außenfläche (Oberfläche der Außenwand) und der Dachhaut bezeichnet. (Wikipedia)[/I]

I have the feeling that the drip edge point you measured is not correct. The drip edge point (also [I]eaves point) is defined as the intersection between the vertical exterior surface (surface of the exterior wall) and the roof covering. (Wikipedia)[/I]

"Our" drip edge point is defined in the development plan, take a look at my first thread, where I quoted from the development plan about this.

"Our" eaves point is defined in the development plan, look at my first thread, where I quoted from the development plan about it

Are you sure that your interpretation is correct? According to that, one could also build this, right?

well, the roof pitch is hardly likely to be that generous. Eaves often count fully towards the GFR starting from 50 cm...

We found a steel door in the guest room (=sleeping area with potentially longer duration of stay) even less attractive.

As an airlock, however, that would be even less suitable, which doesn't really make the toilet better for this purpose.

"Do you remember when Uncle Fritz had diarrhea here and Tom quickly wanted to get to the toilet from outside and ..." *roar*

I hadn’t thought about our bathroom secondary door locking faction yet

Incidentally, I would count a sauna among the living spaces, which means it probably could not claim a boundary development privilege.

The knee wall in the single bedroom is the so-called ‘abseite’ and is not used,

It can’t be used either, since only rubber people would have access. The cat is happy about it

Perhaps the cross-section for understanding:

The planner apparently lacks the understanding that the eaves height legally does not mean the upper edge of the gutter, but the virtual cutting line between outer wall and roof covering.

For the eaves height, the measurement starts on the ground/soil, then up to the point where the roof meets the exterior wall. With a room height of 2.75 and a ceiling height of 25/30 cm (from upper edge of floor slab), you already have your max 3.00 meters.

Due to the bungalow area, the architect is necessary to calculate the number of storeys and the statics. You are only allowed to build 1 full storey, and then there are percentage guidelines for the ceiling height of the subsequent upper floors that must not be exceeded. I can't calculate that with my pencil

Maybe the architect should take care of everything, so get him on board already during the development plan?!
