Are my neighbors allowed to drill into my extension?

Questioner

I recently bought a house and immediately started building an extension at the back of the house. It is a detached house. The side wall of which borders the property of the neighbours. I built an extension in line with my house, so my facade is extended at the back and borders the property of the neighbours. All of this is on my land, so against the property boundary. Now my neighbour wants to hang (drill) some things on the extension. Is he allowed to do this? I myself would not even do it, let alone give my neighbour permission to do this.

Lawyer

If the wall is ON the property line, then that wall is common and the neighbor would be allowed to do that, provided that there is no disadvantage to the construction. But if the wall is completely on your own property, then the wall is exclusively your property and the neighbor is not allowed to drill into it without your permission.

Questioner

Marcel, thank you very much for your response. I read somewhere on the internet that I am supposed to tolerate minor intrusions. Such as hanging small objects as long as the wall is not damaged or the construction is not affected. However, the neighbor wants to do this just to 'harass'. Because he had looked this up. I want to be able to limit him in this.

The wall meets the definition of a private wall

Lawyer

Does the wall serve as a property boundary or is there another structure on the property boundary as a property boundary? You can, if necessary, place a fence in front of the wall, on the property line in consultation with your neighbour, or if there is still space on your own land in front of the property line, so that the neighbour can attach whatever he wants to hang to the fence.

Questioner

The wall, the side wall of my extension is against the property line, in line with my original home. The wall is part of the 'building' and is also against the property line. The current home has been there for 24 years and he has not hung anything on it, now that he cannot digest the extension he wants to drill into it, while he himself has an extension with a construction that is many times larger. That is double standards. Phew, this is all difficult.
