ᐅ Floor Plan for Semi-Detached House on a Slope – Suggestions for Improvement?

Hello,
attached is a floor plan for a semi-detached house (only one half shown) on a sloping site, with a request for comments.
The semi-detached house is planned to be built on one plot, with both units intended for rental.
Currently, the plot is classified as outside the designated building area. Nearby (to the north and on the neighboring plot to the east), houses of similar size (height, site coverage ratio, floor area ratio) have been built in recent years with special exemptions. The informal preliminary inquiry regarding the conditions is ongoing with the local authorities, but I expect a lengthy discussion.
The following considerations were made:
- Maximum width 14 m (plot width slightly >20 m (66 feet))
- 3 similarly sized (bed)rooms of at least approximately 15 m² (160 sq ft)
- 3rd room more important than a garage (garage with boundary line construction likely not possible due to slope)
- Carport as a substitute for a garage
- Studio room if approved, otherwise a shallow hipped roof or green roof
- Living room/kitchen on the “entry level”
The following questions still arise, or I am not fully satisfied with:
- Possibly living room/kitchen in the basement level with direct garden access?
- If the roof terrace is approved, should we skip the balcony at the living room?
- The shape of the living room is difficult to furnish (goal: TV and garden view from the sofa)
- Prefer a garage over the 3rd room? (rental marketability)
- Little or no space for coat storage/shoe cabinet in the hallway (width approx. 1.35 m (4.4 feet))
- Too many windows? (We have this in our house because we love it, but here rental appeal is a factor)
- Planned so far as a semi-detached house with a party wall. Would it also be possible as a duplex with two separate residential units and a “standard” soundproof wall? Advantages? Disadvantages?
Once the basic conditions are clarified with the authorities, an architect will of course be commissioned — hopefully one with creative ideas, as I am not fixed on my sketch.
The basis for my design is long, engaging discussions with the architect during the planning of our own home, combined with a spatial imagination as a graduate engineer and experience in floor plans for VIP aircraft (yes, the sheikh who wants living, sleeping, and reception rooms in planes normally designed for 300 holiday passengers). Please excuse the use of this “drawing software” (you can’t even mirror the semi-detached half). I used boring evenings during business trips and had to rely on an online tool. We’ll see if I find time for a design in Catia…
Thanks very much for all the critical feedback :-P

Friends of ours have the entrance on the upper floor and the living area below.
I would find that terrible on the plan. In reality, it is actually quite okay. A nice, bright entrance area with a wardrobe and guest toilet, then stairs down and you arrive in the open-plan living space.

*confused* Not you! All your designs are fine.
That was an insider joke for everyone frustrated with CATIA at the A-Company.
Hello,
here is a version with an open space in the basement level and the rooms on the ground floor.
The new feature is the entrance on the side of the house. How this can be realized with the terrain would need to be examined in more detail. Retaining walls up to 2 m (6.6 ft) are generally allowed in the setback area.
Another option would be to move the bedroom to the upper floor. However, always having to use stairs to reach the WC is somewhat inconvenient, and I did not want to include a third WC given the size of the house.
The concept with two “staggered” maisonette units requires a bit more thought. I have postponed that for now.

Have you ever considered an external staircase from the balcony?
Some friends have it like this (single-family house): upstairs there is the entrance, living room, and balcony. Downstairs are the children's rooms, which lead directly to the garden.
However, you can also access the garden via the stairs from the balcony.

The entrance on the side of the house is new. How this can be done with the terrain would need to be examined more closely. Retaining walls up to 2m (6.5 feet) are basically allowed within the setback area.
Another option would be to move the bedroom to the upper floor. But having to go up a staircase every time to get to the bathroom isn’t very practical, and I didn’t want to include a third bathroom given the size of the house.
The concept with two "offset" maisonette units requires a bit more brainstorming. I have postponed that for now.That won’t work at all. There’s hardly any proper space in the bedrooms, and access to the bathroom is impossible.
The storage or utility room is disproportionately large – it’s unnecessary and in fact a waste of space here.
And the access to the basement is indeed more like “access to cellar rooms” here.
