The plot is 8,000 sqm (currently with a farmstead, which is to be demolished).
Then it might be that you, if there is no development plan, are allowed to build again like the farmstead?!
No slope, no special requirements on the land plot, no immediate neighbors either, so no uniform appearance that must be maintained.
I would clarify all that. As often read here, you cannot build everything just because there are no requirements. Other laws then apply.
But interesting project! Keep us updated. I'm curious. I like such sprawling houses :)
