ᐅ Build a Semi-Detached House on Your Own?

Hello,

In 2021, I was able to reserve a building plot in a new development area for a semi-detached house. The release of the development area is planned for autumn 2022. The goal is to move in by autumn 2023.

So far, no neighbor has been found for the adjacent plot.

I can’t wait much longer because I need to award the contract for the basement excavation. Of course, I would like to plan together with a neighbor.

The notarization appointment for the semi-detached house plot is scheduled for January.

I plan to wait for a neighbor as long as possible. Otherwise, due to the fixed move-in date of autumn 2023, I will have to start building my semi-detached house alone, without a neighbor.

Please share your experience and opinions with me.

Would you withdraw? I might still be able to switch at short notice to a still-available, less attractive plot for a detached house.

The plot for the semi-detached house is nice, and I would prefer it over the plot for the detached house.

I have never seen a single semi-detached house standing alone. Also, regarding a situation where the neighbor does not want a basement and would then have to follow my building style, I think this is not an ideal start to a new neighborhood... I also think that when the neighbor builds their half, there might be damage to my house wall.

What speaks against starting the build alone, with the risk that a neighbor might only be found months or one or two years later? The semi-detached house shouldn’t collapse in the meantime, right?

Best regards!

First of all, thanks to everyone for your information and experiences!
Some of your comments even reassured me 🙂

You would need to tell/show a lot more about both plots so that we could give our input.

Attached are the two plots from the development plan.
For the semi-detached house, I like the natural protected habitat that cannot be built on – currently a hedge on the south side. Also, the house faces the valley and has only one neighbor.

The biggest issue is (almost) resolved if you build with a basement. The easiest situation is if your neighbor builds without a basement; in second place is if they build with a basement at the same depth. But they might want to excavate deeper than you, either for higher ceiling height in the basement and/or different foundation levels. Therefore, you should already discuss the topic of underpinning with your planner. Unfortunately, most development plans do not require semi-detached partners to build with matching profiles – you can forget about optical harmony. That the twins end up looking as different as Schwarzenegger and DeVito in the worst case, you can at best prevent by buying the neighboring semi-detached plot and passing it on under certain conditions (which of course depends first on your liquidity and tax situation).

The semi-detached house will definitely have a basement with a ceiling height of at least 2.50m (8 feet 2 inches).
Unfortunately, after consulting with the municipality, I cannot buy the neighboring semi-detached plot.
I don’t mind if the semi-detached houses look different.
Roof shape (gable), roof pitch (10-30°), and maximum ridge height (9m (30 feet)) are already fixed.

Insulation needs to be carefully considered, also regarding the setback from the boundary. If the insulation will remain when completing the semi-detached house, you naturally have to set back further – otherwise a joint distance to the boundary is sufficient, which in the meantime will be covered with insulation. Keep in mind that the neighbor will probably not build their half with identical profiles – see above. The hope for volume discounts is not worth seriously discussing: we’re talking about small coins compared to suitcases full of cash (similar to the rubber mats the car dealer adds on top of the "house price"). Peanuts in more than just the literal sense. You can even share the portable toilet on the construction site without using the same contractor.

I will clarify this with the future building company – thanks also for the reminder regarding the basement and underpinning.

Two development plans: left semi-detached house 12,480m² (134,333 sq ft), right single-family house 4,501m² (48,441 sq ft); buildings, streets.

The detached house (ERH) by @goalkeeper or the thread should provide you with good information. But don’t worry: since you are building with a basement, it should be a bit easier for you. Maybe you should start a notice yourself? “Looking for a neighbor”

Unfortunately, “Looking for a neighbor” is not possible because it is managed by the municipality through a selected waiting list.
What do you mean by ERH? Could you send me a link to the thread? Thanks.

You shouldn’t be so stingy with the excerpts; you can hardly see anything. Are both from the same zoning plan area? It’s best to name it here (without a link).

Oh, so you are an applicant for a municipal land sale round – that’s good and not a given that you can also choose another lot. (Not just?) I thought it was about buying half of a lot from a private seller.

Yvonne means an end terraced house (REH, Reihenendhaus). One of our most prominent threads is here: https://www.hausbau-forum.de/threads/reihenendhaus-mit-gue-in-eigenregie-bauen.31198/ – @goalkeeper actually has the situation the other way around; he already built without a basement, and his immediate neighbor (in what I think is a group of three) wants to build with a basement.

You don't need to be so sparing with the openings, you can hardly see anything anyway. Are both from the same development plan area? It’s best to refer to it by name here (without link!).

And in which municipality should we look for it?

You can click on the username yourself and see the posts they made in their own thread…

Looking for a neighbor doesn’t work unfortunately, as this is handled by the municipality through a selected waiting list.

That doesn’t matter: prospective builders who don’t know that the municipality still has plots available can probably be reached by other means as well—advertise, wait for inquiries, and then tell them that you are looking for a neighbor for yourself. Those interested can then contact the municipality.
