Looking for floor plan suggestions for a semi-detached house

A site plan is not yet available (as the plot is undeveloped). The plot is approximately 10.5m wide. The length of the building window is sufficient. I find 7.5m x 11m appropriate. Originally, we wanted 7x10m, but that becomes quite tight without a basement.

Inventory ... Plot is 370m² with south-southwest orientation, 45° roof pitch, permitted eaves heights 4m (north) and 6m (south), boundary building on the left, other semi-detached house not yet built, buildable on the eaves side
Absolutely necessary:
optimal use of space -> min. m³ -> house as narrow (max. 7.5m) and short (10-11m) as possible, solid house, Energy Saving Ordinance 2014, budget 250,000 - 300,000 EUR excluding land including all ancillary costs, no basement, utility room ~10m², external air heat pump + multifunction storage (later solar|photovoltaics) + underfloor heating, kitchen and dining area (south) combined, large children's room (south), no open wardrobe, bright rooms, toilet on ground floor, bathroom >8m², side entrance with carport and extension, bedroom without roof window, no long|narrow|dark corridor, full story height on south side, bedroom on north side
Nice to have:
living room + kitchen combined, bedroom without wardrobe, old furniture fits, Kfw70, large window front (lift-and-slide door) to the garden

no additional costs should be incurred ... dormers, corners, bay windows, elaborate structural engineering, unnecessary living space like a 20m² bedroom or similar
The little house should be practical, minimalist, puristic and inexpensive

optimal use of space

do not incur additional costs ... dormers, angles, bay windows, elaborate static engineering, unnecessary living space like a 20m² bedroom or similar.

I understood

Nevertheless: things like the following

dining area (south)

large children's room (south

bathroom >8m²

bedroom without skylight

bedroom on the north side

are of course nonsense if you insist on them as MUST- HAVEs.

What about a really great design where the entrance is simply on the north, the dining area is in the west (I think you drew that yourself).
Also, a bathroom with 7.5 sqm can have a larger room feeling than a bathroom with 9 sqm.
And that no one designs the bathroom above the living room in the south is probably self-evident here.

The whole must be right! Then you can also live with a skylight or a bedroom in the east.

I experimented a bit and found that the knee wall on the north, for example, causes problems.
Furthermore, I reread your old thread, where it says something about: staircase separated because you are too loud in the evening...
So: it takes time!
Do you want to put the carport on the west border?

What about a really great design where the entrance is simply in the north, and the dining area is in the west (I think you drew that yourself).

To be honest ... I would be extremely reluctant to have the entrance in the front ... but I think I could live with it if the side entrance really doesn’t work out.

are of course nonsense if you insist on them as ABSOLUTELY necessary.

I can understand if that seems nonsense to you. For me it is still a no-go, otherwise I wouldn’t write it.

A bathroom with 7.5 sqm can have a bigger space than a bathroom with 9 sqm.
And that no one plans the bathroom over the living room in the south for you is probably self-explanatory here

And of course 7.5 m² would also work, but you have to set a tendency somewhere. We looked at many bathrooms and the >8m² (regardless of how they were laid out) appealed to us in terms of space.
Yes, the knee wall in the north is a problem at a length of 11m, the rooms in the north become quite small if you want to keep the line with the staircase.

The whole has to be right! Then you can live with a roof window or a bedroom in the east.

hmm, to be honest I don’t want to live with that. There are compromises I accept, but I don’t want a roof window in the bedroom ... then rather no window at all.

Do you want to put the carport on the west boundary?

Yes, we don’t want to pass by any car to get to the house. And there simply isn’t enough space on the property to have a sufficient distance from the car.
My idea is to park the car, get out, open the trunk, and have a short, direct, free, dry way into the house. Hence the carport on the west side and the side entrance.

It is difficult to define what you absolutely need ... those are more ideas you simply wish for. Some more, some less, and if you have free choice, you don’t want to experience certain things again.

Yesterday, a general contractor came who calculated costs of approximately 450,000 EUR (ready to move in including land + outdoor facilities + carport + incidental costs .... everything that arises) for us.
Can that really be true?

Sorry, I quickly found quite a few things earlier... I will get you some links and also post a quick sketch when I am properly online again.

Do you have some links or a sketch? I would be really interested in that.
