Exceptional + generous, how to proceed?

: the entire area may be built on and the floor area ratio is 0.2. I didn’t mention this further because it is not a restriction for me. I don’t want to build that big anyway.
There are no regulations for eaves height, ridge height, etc. One story is definitely the only restriction. An architect looked at it beforehand as well.

: Of course costs and money play a role for me. I do exactly as you wrote: I check my financial framework (€1,500,000, don’t like banks and dependencies, so I pay entirely from own funds), buy a plot of land and check the development plan. Now I check what I get for my money or what I want.
Others have an all-in budget of €500,000, I have €1,500,000 + land. (€1,000,000 house, €200,000 exterior facilities + garage, €100,000 furniture, €200,000 buffer is my rough plan). What is so reprehensible about that or why should I be a troll?

Tastes are known to differ, but I simply prefer large open rooms to several smaller ones. The question is how everything is used. A 30 sqm bathroom with a jacuzzi and sauna is not too big, just like a living room when you combine TV corner, billiard table, fireplace area, library, etc. all together.

: It wasn’t the best year, but I think it should be enough to build an object of these dimensions, right?
I’m now looking forward to your input.

If that is your decision, then you certainly also know why there was another additional payment due? Right?

Well, some people just live from hand to mouth, so the money that has to be paid later would already be spent
