Ideas for building a house on parental land

I absolutely agree with you. But now it’s too late. What has bothered the most or still bothers is that you are never really private. You can say a hundred times that I hate it when someone knocks on the terrace glass, but it doesn’t matter. We put up pleated blinds on the garden door 3 or 4 years after moving in so that we’re not sitting on a silver platter when they are on the terrace. The best time was 2019 when we sowed the lawn and they couldn’t walk on it. Now the deep snow also keeps my mother-in-law away. Now she goes to the front door :D You just shouldn’t ignore that. Before we moved onto the property, they never visited us. Although my mother-in-law, for example, was at my grandma’s every day, who lived in the same apartment building as us. So we would never have thought of it.

One can say 100 times that I hate it when someone knocks on the terrace glass, it doesn't matter.

That's terrible. That's disrespectful towards you. We had the terrace by the street, and it also happened there that people knocked on the terrace door. Sometimes I got really startled. I would put up a fence and lock it, but show that you still like them (if that's the case ;) so visit and such) Initially, they will be sulky, but that will surely pass with time.

Many years ago, a daughter-in-law in our circle of acquaintances had the audacity to install a new lock in her apartment in the shared multi-family house.... that was then the breaking point. You couldn't just walk in anymore if you wanted to....... I have experienced this often with sons who did not want or could not set boundaries with their mother. I would say that politely BUT clearly and, if it doesn't work, also enforce it. Nevertheless, I believe that talking, alongside clear behavior, is also important with older people. BUT I would definitely settle THAT!

Yes, disrespectful fits quite well. I would like to have a fence but at the moment it's not feasible, we have to do it slowly and "unobtrusively". Father-in-law suddenly passed away in June after a short but very severe illness. That would probably be her end now if there was suddenly a fence. Overall difficult and I wouldn’t do it anymore. I didn’t want to hijack the thread but to point out that it can sometimes be advantageous to build on the property, but you can still pay dearly for it. But also, that it is possible to build on hopeless plots. With us, it was also said that only a garage would fit on it but we live in 120 sqm. Just a detached semi-detached house.

I think that doesn’t matter. The OP was last logged in yesterday afternoon...

Oops, yes difficult.

Nevertheless, I believe that talking is also important for older people alongside clear behavior.

Older people... what age are you talking about? Our age?! o_O Next door to us: life partners are building a little house, opposite in the bungalow row, where his parents are also settling (for later to watch the kids and so on). It was often idyllic between the two couples, but often the old lady (eeew, let her be older than me) would walk across the lawn with a casserole dish in her hand... ...until our young neighbor moved out... to another. Since then, the casserole dish from his mother across the way hasn’t come anymore, but curious looks about what their ex-in spe-daughter-in-law is up to. In the end, she too, my neighbor, sold the house.

Get yourself a dog and teach it to only do its business at [schwiemu]. Then she will soon want the fence...
