ᐅ Single-family house or semi-detached house?

For soundproofing reasons, the floor slabs should not be in direct contact.

That idea is unrealistic. In new housing developments, semi-detached house plots are often sold. Neighbors rarely coordinate with each other. Usually, they don’t even build at the same time.

Have you ever actually built a semi-detached house? There is so much ignorance and speculation in this thread.

Around here, it is common to find a partner for the semi-detached house and join forces. Often, you’ll see ads in newspapers or real estate portals that the second half is still available.
Finally, semi-detached houses are now being built. They took two years before the last semi-detached unit was sold. Five semi-detached houses are currently under construction. The sixth hasn’t started yet because the second partner is missing.

With a standard semi-detached house, there is definitely no shared wall. Otherwise, it would be a duplex. The floor slabs and walls do not touch either. If properly constructed, it doesn’t matter what the neighbor does.

Each semi-detached unit is self-supporting; it just looks awkward.

The two halves of a semi-detached house can, of course, be built by completely different companies using different construction methods.

They can also be built at different times. On the adjoining side, it’s only fair not to backfill the excavation pit of the first semi-detached unit too early.

For aesthetic and slightly practical reasons, it makes sense to at least coordinate the height and length of the building structure, as well as the roof pitch. Also, whether to use brick cladding.

If the “cutting edge” is aligned, you at least have a visually unified building, and fewer issues sealing the joints. Later on, for example, you won’t have to climb onto the neighbor’s roof to potentially renew their exterior plaster.

The goal is to achieve 200 sqm (2,150 sq ft) of living space plus a basement.
With a 7m (23 ft) wide single-family house, can you get a good floor plan, or does it feel more like a terraced house? Would you recommend a semi-detached house instead?
The area wouldn't be a problem with 2.5 floors.

Are there no architects or planners on the forum—people who could bring some realism to the original poster? He’s not just building a 10.00 x 14.00 m (33 x 46 ft) house if the neighbor doesn’t agree.

Here, people speculate freely based on the poster’s changing details. He would do well to find a contact in real life!

What does the municipality have to do with it? No zoning plan has been established. Therefore, each landowner has free design options within the framework of Section 34 of the Building Code.

No, because even the first builder must ask the neighbors whether to build on the boundary. Only if the first builds with a setback, no neighbor approval is needed. If you want to build a semi-detached house, the possibility of boundary building should be secured before purchasing the plot.

The associated self-commitment to build on the boundary is the bitter pill in this. The best protection against conflicting interests is that the land is owned by only one party until it is developed. Wise municipalities therefore only allow semi-detached houses once they know the likely parties involved (usually the local housing development expert). In an area governed by Section 34, the possibility may of course arise simply because such buildings already exist nearby.

But if you call a semi-detached house an emergency landing, that says it all.

I think we are misunderstanding each other: I don’t think semi-detached houses are bad in themselves, but in this specific case, due to the narrow plot, there is a dilemma of either coordinating or ending up with a “bowling alley” layout. Specifically, this is not the comfortable situation where boundary building allows arranging a double carport and/or a breakfast terrace differently. It is more a case of “take it or leave it.” From a game theory perspective, this is close to a prisoner’s dilemma.

Of course, everyone can also use their own planner. That in itself is not childish – but looking for the other planner without first checking whether the other’s planner would provide “good chemistry” as a joint planner is somewhat so.

It is also possible to build without coordinating the timing – if the person building second is already on their fourth home-building project, they can easily handle it. But on the first attempt, I see this running into problems.

Even smart municipalities have no influence on whether property owners build a semi-detached or detached house, unless the character of the surrounding area is so clear that only one building type can be approved. According to the original poster, this is not the case here.

Why? If both want the semi-detached house, it’s just a formality.

That’s nonsense!

Municipalities already designate the areas for detached houses or semi-detached houses in advance of announcing a new development. Your “applicants” probably refer to the fact that municipalities often like to bring both semi-detached house partners together before issuing a building permit / planning permission.
