Plot selection for a semi-detached house - Which one would you choose?

Oh, that sounds like a divisible plot, you could approach it with a known semi-detached partner (and clarify beforehand who designs both buildings). But I don’t really like the usage templates here either, so maybe rather a different development area?

Interesting suggestion. I assume such a division of the plot as well as development with a semi-detached house instead of a single-family house could also be restricted by building regulations? In fact, this would be plot 2625 to the left of the two previously proposed.

So we also built a semi-detached house – bought the plot including rough construction work from the mason, there was already a rough floor plan, but the architect was not exactly the best, to put it mildly ;)
But that didn’t matter – we awarded all trades individually with the construction supervisor.
We didn’t know our neighbors before the purchase either, but they are nice, like almost all families in the new development area.
We both built without basements, and we would have done so even if they wanted one.
We had to agree on:
- roof tiles
- shape of the roof soffit
- gutter material
- facade, i.e. the exact brick
- window color
- joint color

That was of course also due to the development plan, which could have restricted much more. So I would clarify that beforehand for a semi-detached house as well.
Often it is also the case: first come, first served and gets to choose everything, and the second is out of luck ;)

Thanks for the hints. I will soon clarify what exactly is stipulated in the development plan regarding the "shared" elements.

Yes, the plots are awkwardly shaped. But I find this pessimism unjustified.
The OP has certainly already seen and experienced some setbacks on paper because he cannot afford it or because plots are not sold by the dozen in his vicinity.
You can arrange the carports in the middle, lay out a partial terrace and sun-facing windows to the south, thus centrally on the plot, incidentally protected by the carport. After all, there is not only the standard thing like a semi-detached house. Then you don’t just have the yawning emptiness of a lawn, but several garden areas. In 20 years these gardens will look more enchanting than the standard north courtyard, slapped-on carport, terrace and lawn at the back.
I would take plot 26, you even have sun in the northwest in summer there :)

Nice to hear something positive about the possible plot for a change :).
Indeed, the situation in our city (Lörrach) is tense, especially the housing market, which is increasingly having an impact on the house market as well.

I like the approach with several garden areas. I will try to draw in actual dimensions of carport, house, etc. to better assess the overall situation.

Because of the DH partner, I wouldn't worry too much now. In fact, two independently functioning houses are being built, so it's not true that everything has to be coordinated down to the last detail. Here with us (also BW) there are plenty of DH and terraced houses where each house looks different. Whether that's visually pleasing is up to everyone to decide, but technically it's not a problem. The only question that should be clarified is whether or not to have a basement, otherwise this can actually lead to high additional costs for the basement builder alongside the non-basement builder. What many people from less densely populated areas don't see: there are often simply no alternatives, probably has been searching for years. Sure, it's not all optimal, but it is quite feasible, as Yvonne also rightly says. Is the location around it good? I find that almost even more important than the plot layout.

ok I first had to look at the map to see where that is ;) but then it's clear that you don't have that many choices...

that you would have to coordinate down to the last detail now is not true.
Here with us (also BW) there are a lot of semi-detached and also terraced houses, where each house looks different.

That's quite a blanket false statement :)
Just because there are different terraced houses doesn't mean they are allowed everywhere.
The magic word is zoning plan.

That's quite a generalized false statement :)
Just because there are different townhouses doesn't mean they are allowed everywhere.
Development plan is the magic word.

Of course, the restrictions of the valid development plan apply.
However, these are often not particularly restrictive regarding the appearance. Sure, heights are basically always specified, as well as the floor area ratio, which then sets certain maximum dimensions.

We have a current building area with semi-detached house plots, where everyone can do whatever they want. I also had a plot in sight there and would have easily gotten approval for an architect-designed house with a flat roof next to a usual 2.5-story building from the general contractor with a gable roof. That may not be the rule, but if you look at many city/village images, it is also not the absolute exception.

But aside from that, of course it makes sense to coordinate, the earlier the better.
I just wanted to express that you shouldn't necessarily refrain from semi-detached houses just because then the neighbor basically determines the exterior view.

In fact, this would be plot 2625 to the left of the two previously suggested.

From your plan section, there is no indication that this "ED" would not also be buildable, however, in this particular case, the access situation complicates a subdivision.

But technically that is not a problem.

Well, then take a look in the green forum, "Party wall semi-detached houses," where the current case is as follows: The questioner has built solidly, as was planned for the neighbor as well, with a soundproof mat in between. Now the neighbor switched to timber framing, and his builder says it is not necessary. Unfortunately, the fact that party walls are no longer single-layer nowadays does not take away their characteristic as a friction surface between uncoordinated construction concepts.

Well, then take a look in the green forum, "Haustrennwand Doppelhaushälften", where the current case is as follows: The questioner built solidly, the neighbor was supposed to do the same, planned with soundproof mats in between. Now the neighbor changed to a timber frame, and his builder says it's not necessary. Unfortunately, the fact that party walls today are no longer single-layer does not take away their characteristic as a friction surface between uncoordinated construction concepts.

Well, just because a builder is now making a mountain out of a molehill doesn’t mean it’s not possible to have two semi-detached houses built by different builders, one maybe solid and the other timber frame? Of course, it would have been better if he had built a proper external wall, but sealing the joint now, with or without a few centimeters of soundproof mats, really doesn’t change much. He could just keep his feet still and see what the guys at Finger do, somehow they will manage to make it tight.
