Floor plan of a single-family house with a granny flat

So in expensive locations, very large houses definitely sell like hotcakes... For us, that was also one of the reasons to build here. Because I know... that I can sell our house with a snap of my fingers. Our house is certainly too big for old age, so we didn’t build it age-appropriately but already plan for a sale in 20...25 years (whenever that may be). Location location location... that’s the deciding factor.

As a buyer for our house, I could well imagine a tax advisor or something like that. Office downstairs, living upstairs.

In the end, however, in my opinion, only the location counts. The buyer will renovate anyway. This property has a cool location. A very good location, even.

Somehow, I honestly feel like the house lacks a concept...

You want a granny flat, but it’s not really supposed to be rented out for now.
You don’t want KFW either.

So why spend the money on the granny flat? With KfW, that makes sense—you can get the repayment subsidy for two residential units. Okay, if you’re planning to have a granny flat anyway, then you take advantage of that.

But if I don’t want a KfW loan and I’m not really planning to rent out this granny flat, why is it being built?

To open a cat breeding operation sometime in the distant future? Although I wonder whether the spatial concept of a granny flat is suitable for that, but that’s another question altogether...
To maybe, possibly have the in-laws as subtenants someday???

Maybe, possibly, and under certain circumstances… It’s still not clear to me why the granny flat is necessary.

That would be too little for me personally to justify spending quite a lot of money on it.

You want a house for PLANNED 4 people without knowing if the hoped-for baby boom will actually happen.
And what if the last child in the bunch comes as twins? Then the spatial concept won’t fit again...
Well, that applies to many, and I always have a bit of a gut feeling about that.

And then I see a house plan that suits a building plot on flat ground better but is now being forced onto a slope.
There are really cool slope solutions!

I don’t want to go into detail about the room layout, etc., for me the whole concept is not coherent. So I’ll just throw a few points out there for you to think about—or not:

Slope location! That’s a challenge, no question. But there are also quite creative solutions for that. Here I don’t see a single idea where the POSSIBILITIES of such a condition were even remotely used. For example:
- Gallery! Kitchen and dining area downstairs and via a gallery upstairs to the living area. That would also better accommodate the narrow floor plan than placing the living areas side by side. Furthermore, you can optimally use the mostly unobstructed view of a slope location.

Possibly plan children’s and parents’ areas on two different levels as well. Parents behind the living area, children behind the kitchen or downstairs, and possibly a small room near the parents that can be used as a toddler’s room and later as an office.

Dry construction offers many possibilities; I might not fully finish all the rooms yet. For a large family, it could initially be one (or even two) generous rooms that can then be divided depending on how many children come (or don’t). The advantage is that I can then perhaps plan this area completely differently if life writes a different diary (and instead of a baby boom, maybe the cat breeding operation becomes reality).
The same goes for the granny flat: if I do not want to use it as such yet, I would only plan it in the overall layout but not fully realize it; if it turns out to be 2 times 5 children, I can also change plans accordingly here and keep all options open.

Just a little food for thought.

I think the house doesn’t fit the plot now. It’s narrow and steep. That has to be taken into account to get the optimum out of it.
This design is still miles away from an optimum for me; but if your heart is set on it, then do it this way.

Apartment: That makes sense if you plan to do it. It is completely legal and by no means borderline. Karsten
[B]Tax tip for landlords[/B]
A house with an apartment can also serve as a tax-saving model, provided you rent out the apartment. As a landlord, you do have to pay tax on the rental income, but in return, you can deduct the loan interest as advertising expenses from your taxes. Therefore, the motto is: allocate as many construction costs as possible to the rented apartment and less to the part of the house used by yourself. Practical tip: Strictly separate the two living units by concluding two different construction contracts and accordingly taking out two different loans, each clearly and objectively assigned to one of the two living units. Instead of concluding two construction contracts, you can also specify exactly in the notarized purchase contract which part of the total price is allocated to which apartment. To obtain the highest possible loan interest on the loan for the rented apartment, this part of the house is financed entirely through a loan. The equity flows entirely into the self-used part.

Correct, "provided that the [Einliegerwohnung] is rented out"

But that doesn't seem to be planned at first...

If she reads the quote above, she will rent out.

As much as I agree with Climbee on many aspects, I must wonder why it is questioned here in this draft whether the planned influx of children will actually take place. I have read that 80% of the house designs presented here include two children's rooms, even though none are yet present. And it mostly concerns houses larger than 159 sqm. It is never questioned whether the planned children's rooms make sense, even though additional spaces like offices, hobby rooms, etc. are also planned. I often think my own thoughts about this, but if the desire for two children exists, the children's rooms should also be planned. As here - in a new build, for medium-term planning, I would not start by omitting walls only to build them as planned after 5 years. I have thought again about other options for the house, but I believe TE no longer has the leisure to change her concept. The granny flat is set, as are the four stairs. With kind regards briefly
