Floor plan, building with tree, granny flat, and existing buildings

I don’t know what measurements are shown to you in your program, but for me it looks like just under 90 sqm. Could it be that the workshop/carport was included in your calculation? As a reference, I took the 13.50 from the original plan on the left. [ATTACH alt="Bildschirmfoto 2023-10-21 um 15.53.21.png"]82468[/ATTACH]

Thank you for redrawing. I have 9 m*12.5 m for the house. The original was 10 m * 13.5 m The sketch shows that my statement is correct. The usable rooms are significantly larger. If I leave out the wall stub, as shown in post #70, then the bedroom is no longer so cramped, but if you want to separate it, a curtain will do in a pinch.

Unfortunately, the 4 minutes again? Sorry.

Here is the correction.

If I leave out the wall stub, as shown in post #84, then the bedroom is no longer so cramped, but if you value separation, a curtain will do in a pinch.

135m2 * 0.8 is about 108 m2 living space

112.5 m2 * 0.8 is about 90 m2 living space

18 m2 * 3 k = 54 k cost savings.

We had a case here some time ago where someone had to build a house around the oak tree. The plot was much smaller then. I don't see it quite as extreme here. With the reduction to 9*12.5 m as I have marked, you are further away from the beech with the new building than with the existing house. The alternative, in my opinion, is rather a narrow house with an extension or bay window.

And we would also very much like to avoid stairs in the open living area...

That is often the reason why everything is lined up.

but somehow just lined up next to each other, which results in large hallway areas or similar.

… and depends on the size of the hallways.

For example, the fact that the front terrace is drawn into the beech tree is actually a small thing, but it also doesn’t exactly boost the mood.

Why? The crown starts higher up and can provide a lot of shade on the terrace for a loner. Of course, you could also not just chop off the upper floor at the gable end, but cut out a pie slice and glass the gable, to have the beech tree inside the house :) It doesn’t have to be the expensive full-area glazing, but a floor-to-ceiling window without a railing, i.e. a rotated window band, to always be able to see the tree in all its glory, would be affordable.

What would of course be the most obvious solution, to reduce the attic, is the knee wall. That’s how it has always been done, instead of creating an expensive flat roof: without a knee wall or building it small and installing knee walls inside or using the walls for built-in wardrobes. The builder with the oak tree right in the middle of his property is, as far as I remember, User . In the end, he built a triangular shape, with a great view of his oak.

I immediately thought of Oakland as well, but in my opinion the options here are still a bit cheaper.
Another suggestion in favor of the beech:
