House construction provider in Baden-Württemberg

Thank you all for the answers and also to you for your hints. I am currently reading your thread, which might take a bit longer.

Planning a semi-detached house in the fog is a task for someone who has killed both mother and father. I recommend the search terms "11ant Doppelhaus" and "Mitkellerer" for the first appetite killer

I am basically aware of the problem and have already read a lot about additional costs. The problem is that the plot has a great location, great view, good place, the size fits us (bigger is always possible), and the development plan is a dream. So, no question about not taking it.

We know that the other side is supposed to be sold, but this has not happened yet. If I'm unlucky, this will only happen in 2 years and I will wait with my plot until then. Therefore, I have no choice but to get started now and make all preparations, hoping that in the meantime a sale will take place.

PS: There are no requirements from the municipality that both semi-detached houses must be identical. Not even regarding the exterior color.

Don’t let yourself be unsettled. Build your house the way you imagine it. If the other semi-detached house is ever built later on, they will just have to adapt to you. Ideally, you build a basement. Then no underpinning by the neighbor will be necessary later on – if you build with a slab and the future neighbor with a basement, it will just be significantly more expensive for him.

And regarding the price of the basement: it will certainly cost you at least 60k – depending on how much material you have to dispose of or not. In our building area (northern Ba-Wü) the basement builders pay between 40 and 70 € per ton for disposal.

It is a slight sloping plot where the building authority suggests a ground-level basement on the street side and then the garden on the other side on the ground floor. Of course, this does not have to be followed, but it makes a lot of sense at this point. Therefore, the neighbor will probably also build with a basement (= cellar). Regarding additional costs for safety measures, I have now arranged an appointment with a construction company.

The disposal costs are a good point. We hope to be able to use some of the material for backfilling the garden. I do not yet know how feasible that is, but it will also be a topic in the appointment.

I don’t yet know how feasible this is, but it will also be a point in that appointment.

The contractor won’t be able to tell you that either, but only a soil survey that shows you the condition of your subsoil.

We initially had almost a meter of clay soil, which should not really be used for filling the garden.

How do you want to build 16x22m if you are only allowed to build 0.4? There is only the maximum footprint of 200m2

Hello, how do you come to 16x22m? Half is supposed to be 8x11m = 88sqm So two halves would be 88sqm x2 = 176sqm. However, in this post I am mainly looking for information about experiences with providers. Those who have a good price/performance ratio. The focus is on getting information about providers.

You write

"a semi-detached house (2DHH) is to be built
- Floor area per half approx. 8x11m
- Allowed is a TH=4.5m and FH=8.8m (gable roof)
- Size of the building plot approx. 500sqm"

If anything, it should say semi-detached house half. That is why the 500sqm would be too small but would be okay for 1 semi-detached house half.

Unfortunately, I do not understand exactly what you mean. The area of 2DHH would be 176 sqm. If the area of the building plot is 500 sqm and 0.4 can be built on, that would be 200 sqm of possible buildable area.
