Which prefabricated house provider - prices, experiences?

"Granted," but it's also sufficiently compact (it was only meant for me and my 1.40m bed...), so actually not a full-fledged bedroom..." From afar, I like it. My personal taste is that I want nothing else in our bedroom but a bed, a few pictures, and a large plant. I personally don't appreciate wardrobes in the bedroom. What remains for me, especially due to the non-rectangular shape (it's like a smaller rectangle cut out at one corner), is some garden.

More important to me than subjective "too tight" discussions right now is actually the question of whether the arrangement of the rooms basically makes sense or if the floor plan is complete rubbish.

Where is the limit there? For me, the bottleneck before the staircase entrance would be complete rubbish because it severely impairs life. But if you want to know whether the house will collapse because the statics are incorrect, then I don't see any problems here.

I think it's great that it is not one of the two corner plots and that on one side you only have trees and greenery. That's wonderful. And that you got a building plot so cheaply makes me happy for you.

... It seems that the ownership situation of parcel 75 is quite complicated (several nested communities of heirs) and in addition, there is a usufruct registered for the rear part - if they were not all still in dispute, it could still be tried. ...

So, I somehow don't understand you.
In another thread, you write that there should be at least 1.20m before the stair landing. With us, it's 1.40 or 1.50 if the entire 7.30m is used, and that's so little that the entire floor plan is rubbish?
