ᐅ Are L-shaped retaining blocks problematic on the neighbor’s side due to a slight slope?

Hello.
I recently had a conversation with the building authority regarding our wish to backfill the property, which has a slight slope of 70cm (28 inches), with soil after completing the house. They said that L-shaped retaining walls up to 1m (3 feet) high at the property boundary do not require a building permit / planning permission. That sounds good to us, of course. We also wouldn’t need to ask the neighbor for permission.

However, I find communication important. In principle, I don’t think the 70cm (28 inches) retaining walls would bother the neighbor, as they would be on his north side. What confuses me is the following: the neighbor will likely want to build a garage or carport as a boundary structure on his north side. If we also place our retaining walls right on the boundary, wouldn’t his garage clash with our walls?

Does anyone have experience with planning this in advance so that we don’t disturb our neighbor with our walls, and he doesn’t disturb us with his garage? I am concerned that if our boundary walls are directly against his garage, moisture or similar issues might occur. I’m not very knowledgeable about this. Perhaps someone has been in a similar situation and can share their experience.

You cannot build your L-blocks ON the property line, but ONLY ALONG the property line. That way, nothing will interfere. However, if you already know (or strongly suspect) that the neighbor plans to build a garage there, I would discuss it with them. Apparently, you can do it anyway.

Hello,

I would also try to have a conversation. After all, it is in his interest as well, or you might be able to save using L-bricks along the length of the garage (possibly), or the neighbor can better adjust their garage.

The L-shaped blocks will be on your property, so why should they interfere with the neighboring garage or carport? In any case, with the neighbor's agreement, you supposedly want to live there peacefully for life [emoji6]

The neighbor’s garage would be at a lower level than our property. Where his garage is at street level, that’s where our L-shaped blocks start. So the garage wall would be directly adjacent to our L-shaped blocks. It’s not easy to explain. I could imagine that there needs to be a gap between his garage wall and our L-shaped blocks for air circulation or something similar. Do you understand what I mean?

Then just keep 5cm (2 inches) away from the boundary and that’s fine.
