ᐅ Boundary construction – gap between houses

Hello,

we are currently still in the planning phase for a plot with a boundary wall construction. The neighboring house is about 15-20cm (6-8 inches) from the boundary, so now the question arises how to deal with the resulting gap in boundary wall construction.

No one can plaster afterwards or fill the gap, which I imagine could be quite problematic, especially with a prefabricated house.

Does anyone have experience with this?

You are generally not allowed to build a residential house right on the property boundary, unless it is a terraced/semi-detached house (in which case, to my understanding, the neighboring house should be directly on the boundary and not 20cm (8 inches) away). Therefore, this rule usually only applies to carports/garages and garden sheds.

Yes and no. Unfortunately, we had to withdraw from our contract because we had issues with the architect assigned to us. The plot of land is, of course, the same.

We are currently in contact with the building authority. We are only allowed to build aligned with the street, but both neighboring houses are not built directly on the property line.

We would like to clarify in advance how to handle the resulting gap and whether a prefabricated house with a timber frame construction would even be feasible.

What exactly do you mean by an “assigned architect”? That sounds like something from a state-run restaurant in East Germany where the waiter seats you even though there are plenty of free tables ;-)

We are only allowed to build flush with the street, but both neighboring houses are not directly on the boundary.

I would consider it unreasonable to interpret the concept of flushness literally and precisely down to a few centimeters, which clearly doesn’t reflect reality. An extension aligned with the boundary wall — I’m assuming it’s the yard wall — should sufficiently meet the flushness requirement. I also see the obligation to build an extension as one-sided, and since it’s not clearly defined, it’s up to your choice whether to attach it to plot 280/1 or 283.

Cases like this used to occur regularly, and the gaps were usually closed off with a board (since mice can get through, it was always made accessible to cats as well).

I expect the salespeople to confidently say yes, but in my opinion, no. A traditional timber frame construction might be possible, but a fully prefabricated house that is simply assembled on site doesn’t seem feasible. Without at least some on-site custom work, I don’t see how the building or the boundary line can be fitted accurately enough. Have you looked into why the plot appears to be currently unbuildable, according to the plan?

Hello Hamdu,
we have run into the same unplanned problem. The plan was boundary construction next to an old barn. The building permit / planning permission has been approved and construction is supposed to start in 5 months. But now the surveyor found out that the barn is not exactly on the boundary but skewed (or the boundary was likely established after the barn). Now we have a gap ranging from 0 to 50cm (0 to 20 inches) between the boundary and the neighboring building. And initial ideas from the prefab house company.
How does it look for you?
