ᐅ Neighbor plans to build a semi-detached house with a staggered layout

We are building a semi-detached house directly on the property boundary. Our neighbor now wants to build later with an offset of more than 1–2 meters (3–6 feet) from us – meaning not directly adjoining. In conversation, we had the impression that he is not fully aware of the construction-related consequences of this decision. We have already completed planning and obtained the building permit / planning permission, and we want to start soon.
We wonder how to kindly point out that this gap will cause significant additional risks and costs—for example:
- He will need a separate fire wall and is not allowed to extend insulation, plaster, or roof components beyond the property boundary.
- The insulation of his boundary wall must still be fully installed and permanently protected, which will be difficult without an overhang or sufficient working space.
- The gap that arises must remain sealed, accessible, and maintainable—otherwise, issues such as moisture, debris, and frost damage may occur.
- Base, roof, and metal flashing work will become more complicated and expensive on both sides.
- Our kitchen exhaust is located on that side, and we want to avoid problems with condensate or heat radiation affecting his wall.
- Overall, the offset creates costs that could be avoided with a direct adjoining build, considering regulations like the Building Energy Act, BayBo, and others.
What is the best way to approach this topic without giving the impression that we want to interfere? We simply want to avoid future disputes and clarify who is liable for what if he chooses this solution.

I assume the neighbor is simply taking the opportunity to build a covered terrace. That may be the case. It is always helpful to find out what the real intention is. Nobody wants an expensive offset just for the sake of an offset. So if the issue is about privacy screening, you have options to discuss alternative solutions that meet your neighbor’s goals without costing you money or causing stress. Once the conversation reaches this point, you’re no longer debating the disadvantages of the project versus your neighbor’s plans, but rather focusing on achieving both goals together. This approach is very effective for maintaining a good, long-term neighborly or shared living relationship.

Building boundary = limits that cannot be exceeded but can be set back (usually blue)
Just to add a point of view here: staggered facades are quite common in our residential area. From what I can estimate, out of 50 semi-detached houses, at least 30 have staggered designs. This is because the plots are not laid out perfectly straight, and I don’t find it a problem at all—it actually adds some variety.
PS. Even if they wanted to build their semi-detached house larger than yours, you wouldn’t be able to prevent it.

In the past, buildings were constructed inefficiently without insulation anyway, so the situation was different back then. And with the offset, both corners of each semi-detached house need extra groundwork and deep strip foundations because of the elevation levels towards the street.
