ᐅ Looking for design ideas for a semi-detached house floor plan.

A site plan is not yet available (since the plot is undeveloped). The plot is approximately 10.5m (34 feet) wide. The length of the building area is sufficient. I find 7.5m x 11m (25 feet x 36 feet) appropriate. Originally, we wanted 7m x 10m (23 feet x 33 feet), but that would be quite tight without a basement.

Current situation: The plot is 370m² (approximately 3980 sq ft) with a south-southwest orientation, 45° roof pitch, permitted eaves heights of 4m (north) and 6m (south), boundary development on the left side, the other semi-detached house is not yet built, buildable on the eaves side.
Absolutely necessary:
optimal use of space -> minimum cubic meters -> house as narrow (max. 7.5m (25 feet)) and short (10-11m (33-36 feet)) as possible, solid construction, compliance with the 2014 energy saving regulations, budget 250,000 - 300,000 EUR excluding land but including all additional costs, no basement, utility room about 10m² (108 sq ft), external air heat pump + multifunctional storage unit (solar/photovoltaics planned later) + underfloor heating, kitchen and dining area (south) combined, large children’s room (south), no open cloakroom, bright rooms, guest toilet on the ground floor, bathroom larger than 8m² (86 sq ft), side entrance with carport and extension, bedroom without skylight, no long/narrow/dark corridor, full ceiling height on the south side, bedroom on the north side
Nice to have:
living room and kitchen combined, bedroom without built-in wardrobe, compatibility with old furniture, KfW 70 energy standard, large window front (lift-and-slide door) to the garden

No additional costs should arise from dormers, corners, bay windows, complex structural design, or unnecessary living space such as a 20m² (215 sq ft) bedroom or similar.
The house should be practical, minimalist, purist, and affordable.

I understand.

Nevertheless, things like the following

are obviously nonsense if you insist on them as ABSOLUTE requirements.

What about a really great design where the main entrance is just on the north side and the dining area is on the west (I think you drew that yourself).
A 7.5m² (81 sq ft) bathroom can feel larger than a 9m² (97 sq ft) one.
And it’s probably a given here that no one would locate the bathroom above the living room on the south side.

The overall concept has to work! Then you can live with a roof window or a bedroom facing east.

I tried some variations and noticed that the knee wall on the north side causes problems, for example.
I also reread your old thread where it was mentioned: staircase separated because you are too loud in the evenings...
So: it takes time!
Do you plan to put the carport at the west boundary?

To be honest... I would really resist having the main entrance at the front... but I think I could live with it if the side entrance really doesn’t work out.

I can understand if you see that as nonsense. For me, it’s still a no-go, otherwise I wouldn’t be saying it.

And of course 7.5 sqm (81 sq ft) would work, but somewhere you have to set a general guideline. We looked at many bathrooms, and those over 8 sqm (86 sq ft) — regardless of layout — felt comfortable in terms of space. Yes, the knee wall on the north side is a problem; with a length of 11 m (36 ft), rooms on the north end become quite small if you want to keep the line aligned with the staircase.

Hmm, to be honest, that’s something I don’t want to accept. There are compromises I’m willing to make, but I don’t want a roof window in the bedroom… I’d rather have no window at all.

Yes, we don’t want to have to walk past any car to get into the house. Also, there simply isn’t enough space on the property to maintain a sufficient distance from the vehicle. My idea is to park the car, get out, open the trunk, and have a direct, short, dry path into the house. That’s why the carport will be on the west side and the entrance on the side.

It’s difficult to determine what you absolutely need… these are more like preferences you simply wish for. Some people want more, some less, and when you have a free choice, you want to avoid repeating past experiences.

Yesterday, a general contractor came by and presented us with costs of about 450,000 EUR (turnkey including land + landscaping + carport + additional costs... everything that comes up). Is that really possible?

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

Do you have some links or a sketch? I’m really very interested.
