Small semi-detached house with pitched roof - recommendation?

Hello,

I have been offered a very small building plot with approx. 9.5m x 19.5m, max. eaves height 7.5m.
The plot is in BW, near Pforzheim. The adjacent building plot is still available and belongs to the neighbor, who uses it as an extended garden.

I have browsed through several prefabricated house providers over the past few weeks. The house should be 1.5 stories and about 100m². So quite small as well.

I can do the floor coverings, tiles, and painting/wallpapering/doors myself. Preferably KFW 55/40/plus.

No basement, as it is 50m from the river. My only special requests are a barrier-free shower and maybe an extra roof window.

However, I want to stay within 300,000€, otherwise financing will be difficult. My calculation:

190,000 € house including foundation slab
50,000 € ancillary building costs
60,000 € plot
---------------------------
300,000 €

The only provider offering a house in this price range is Danwood.

Can I also manage this with an architect-designed house?

Can you recommend other providers to me?

Best regards
Pascal

If I may recommend a horror movie to you: - there you can read about the worst-case scenario. You will also find plenty of reading material by searching the forum for "Ohnekellerer," "Mitkellerer," or "Doppelhaus 11ant." In short: I generally recommend coordinating with the builder of the other half, preferably with a joint planner (which does not have to mean mirror-image houses). Every point where the profiles of the two halves differ on the shared side is potentially a sensitive spot. It is especially tricky when the first builder wants to build without a basement and the second wants to build with a basement. One being "solid construction" and the other "prefabricated house" is comparatively easier to manage. But overall, semi-detached houses managed by two individual builders are something for people to whom one might wish a voodoo curse. This is, from many aspects, a type of project that is practically only suitable for developers. For first-time builders, it is a biblical trial.

Addendum:

I have been offered a very small building plot of about 9.5m x 19.5m, max eave height 7.5m.
The plot is in BW, near Pforzheim. The adjacent building plot is still free and belongs to the neighbor, who uses it as an extended garden.

Is this even a semi-detached house plot, or are you only thinking along those lines because of the width? - otherwise, it could simply be practically unbuildable at such a narrow width, since outside Tokyo, you will hardly find experienced architects for house widths of 4.5 m.

Hello, there is already a development plan. The other building plot belongs to someone who is basically the neighbor using it as a garden and does not want to sell it for now or anything like that. That means if I were to build, I would be the first and no one else would build. If someone builds at some point, it would most likely be without a basement, since the property is about 50m from the Nagold and flooding can occur. In BW, a distance of 2.5m to the neighbor applies, which means a house width of 7m is possible, which in my opinion results in a sensible house. Any recommendations for affordable providers? Best regards Pascal

The house should be one and a half stories and about 100m²

190,000 € house including foundation slab

So you are talking about around 1,900 €/m². That is basically impossible - unless you buy a shell house and do a lot yourself.

In BW a 2.5m distance to the neighbor applies, i.e. a house width of 7m is possible, which in my opinion results in a sensible house.

But the building line must be observed on both sides. That makes 4.50m. Or am I mistaken?

It is a semi-detached house, I have to build up to the boundary on one side. So, 9.5 - 2.5 = 7m. What would be a realistic price expectation? I can definitely do some work myself, as mentioned above.
