Floor plan design for a two-family house on a slope

I wonder if he might get a bit upset. *ponder*

Create it in a terraced manner. There is no other way.

Long, long, far too long nothing has happened here. It was due to the still pending building permit. However, we finally have a verbal approval now, so things will continue here soon. But it was also a exhausting building permit phase! Nobody wishes that on anyone. As soon as the permit is available in writing, current pictures of the floor plan will follow.

An explanation will also follow in this post:

The building application was approved. We can get started. Even before the work began, it was already more than an unpleasant process... :-( It took 201 long days for the approval.

Dealing with the authority was really not easy. "Minor excavations" do not exist for the authority. In the end, the building application was withdrawn and a new one was submitted, which has now been approved. As a way out, the basement was enlarged towards the north.

Attached are the current floor plans and elevations/section.

I remember...

I still don’t understand why there is such a compulsive refusal to separate the parent area?!
Guests will hardly use the main bathroom anyway, since there is a guest WC; children, on the other hand, could still go in.
The advantage would be a certain privacy.

I only think about the man sitting at the dining table playing cards with friends, the woman already in bed in her nightgown waiting in the bedroom. If she has to use the toilet, she can only get to the bathroom via the small, useless hallway, where she then stands on display.

With the smallest changes, a dressing room would be possible without any disadvantages...

I would also connect the shower wall to the top wall of the plan. As it is now, the wet corner is right at the bathroom entrance, where you come out of the shower. For someone walking in socks, an insurmountable obstacle.

Where do you have space for a wardrobe? With 2 small children (soon 3 waiting), I imagine it pretty cozy in the small windbreak.

Thank you very much for your suggestions. We will discuss the conversion to a dressing room again. It is clearer with the shower. I have always oriented myself to the marked 2.38 m. I thought the wall was about 1.80 m long, but it is only 1.20 m. This will most likely be corrected according to your suggestion. Thanks!

At the moment, the "energy concept" is still on my mind. Unfortunately, there are no data available yet, such as heating load or prices. For me, the following 3 alternatives are available (but it is also very difficult. There are currently a multitude of options).

a) Heat pump operated/supported by photovoltaics and solar thermal energy
b) Heat pump operated by photovoltaics and geothermal energy
c) Heat pump operated solely by photovoltaics

From the perspective of incorporating as much renewable energy as possible, I find a+b good. However, it is significantly simpler and I fear also not more economical than c.

Congratulations on the building permit!

I would also immediately support the change to matte.
What would really bother me, however, is the narrowness at the entrance. You almost fall down the stairs when you come in.
If it were mine, the straight staircase and the chamber would be thrown out. A piece of the basement would be cut off for the half-turned one. But of course that's a matter of taste – especially since then the space in the chamber would be missing, whatever it was meant for.

I find the vestibule too small. The wardrobe accordingly as well. The skylight by the shower is a great idea, but a functional wardrobe would probably be more important to me in that spot.
