Floor plan design - Constructive criticism welcome

I personally find that a gallery area above the dining table position always a bit of a turn-off. It gives the dining table a sort of hall feeling, the lighting for the dining table also becomes more difficult, and especially there people like to sit with friends and chat .. and everything ends up nicely above the children’s rooms. Just something to think about ;).

I would also like to know the dimensions of the property: width and length of the short part.

I do not see a granny flat either for the same reasons as Kerstin.

The width of the property is 19m. The length of the short part is 24m. We are already working on a new floor plan. We found a floor plan on the internet that might fit. It now still needs to be adapted to our property.

I can understand the arguments against the granny flat. However, I am convinced that the apartment would find a tenant even before completion. There is an absolute shortage of housing for singles, young skilled workers, young couples, etc. in our area. For example, we have been looking for a rental apartment in the mentioned town for a long time for the period after our return. No chance. In the newly developed building area, I only know two properties with a granny flat. Demand is constantly growing. Depreciation is interesting, allocation of future repairs and modernizations, second KfW loan, equity is entirely used for the self-occupied part, the granny flat is 100% financed, during our next foreign assignment part of the house will be occupied, if one of the children later gets into "difficulties" the apartment can help, etc.

Personally, I always find a gallery area above the position of the dining table a bit of a turn-on.

More like a turn-on, b and n are right next to each other ;-)

Oh, I definitely also understand the arguments "for" it. The problem is that they lie on different sides: those "pro" are almost all on the economic side, and those "contra" almost all on the construction side. Without a hillside location, a reasonably attractive granny flat is more complicated to build, insofar as a basement apartment is meant. And a ground-level granny flat requires a larger plot of land.

Practically, this means: if you want a granny flat, you either need a villa-sized plot even for an otherwise normally sized single-family house, or a hillside location. If the plot is "only normally sized" and flat, you have to artificially excavate the basement or basically build an inverted one-and-a-half-story house: with the larger part of the room program on the upper floor. Exactly these planning consequences deter many home builders in flat building areas from building more than a single housing unit.

On the internet. I'm curious ;-)

Oh, the arguments "in favor" are certainly also valid.

I don't agree at all. The rental income from a granny flat could never ever compensate for the fact that I have to share my land and my house with someone. Someone is constantly trampling through my garden and eavesdropping on the wall. Never! When you calculate the construction costs, ongoing costs, taxes, and hassle against it, it’s always a losing proposition. For the kids - okay. Family is, of course, something different. But in that case, I’d rather build a two-family house right away. I’m seeing that with my niece right now. If it weren’t possible to have two complete apartments (2 adults / 2 kids) with enough space, she would never have moved back in with her parents.
