Fascinating and frightening at the same time that after nearly 2 years I finally look into the forum again and you still haven't quite finished with all this back and forth and crisscrossing with the neighboring buildings. Hopefully it will really have a good ending for you soon with the construction :)
Oh... we just make everything look better for ourselves: increased interest, construction, and land costs, and fortunately we did everything right from that side - for that we just had to "bleed" a little more.
And when we see that a terraced middle house in the street was sold for nearly €800,000 a few weeks ago, then we know we built here still "cheaply," but with the cost of many nerves.
Besides ours, we also have a really nice neighborhood where the children can play together on the play street or the kids just quickly go over to each other's garden or house. That is also worth a lot to us. Only young families with children live here - and it is also nice to see how ours grow up in such a great environment.
