Narrow house on a narrow hillside plot

possibly also option to rent out,

Again: 320cm inside! This is something for individualists and a project that wouldn't just be created by a normal architect. And then, yes, it will probably actually be a creation in terms of copyright law. You don't rent something like that out. Laugh

Of course, more soberly considered, you can also create living space through the simplest container construction.

This will not become a rental property. Too expensive, too individual.

4 m interior width is already much more than 3.2 m.
For 2 people who live and think openly and have a large financial scope, one can certainly plan with 3.2 m room depth without the double bed only fitting if one crawls in from the foot end.
The rooms are strung together like pearls on a necklace.

Take a look at your rooms and imagine them with 3.2 m and walking paths.

The dining area is also always fully occupied and also a passage to kitchen, living room, WC, stairs.
So Erna has to pass Günter even if neither of them are elves.

We have a narrow (10 meters wide), but quite long (60 meters) garden plot that we could build on (building inquiry positive) [...] However, we do not have to build in order to live in it ourselves, that is of course possible, but not mandatory.

Why would you even bother to build on the garden plot then? If this parcel is allowed to remain a garden, there would certainly be very interested tenants for it.

Simplest container construction also sounds interesting, how does that work with all the connections etc.?

The parcel is located in a very quiet area and there is residential development on the left and right, hence the consideration of building on it, simply a great spot. But if the restrictions are too great, of course it will remain a garden. But probably there won’t be much more than the ongoing costs plus a small pocket money as rent.

much more than the ongoing costs plus a small pocket money is probably not available as lease

But you have not yet dealt with the demand for plots, and this would even be free of association.
