Single-family house with a hip roof, approximately 340 sqm

Yvonne showed very well how it is with the bedrooms ... you can see that. The left and middle child have a dark room, especially in winter ... no sunlight. And the middle child has a window for nearly 27 sqm room that is less than 2 sqm in size. North arrow is one, the property is large, we do not know how it looks, what the surroundings look like, what else is supposed to happen on the property. All this is absolutely necessary knowledge for the floor plan design.

I have slightly expanded the site plan.

Haha... dressing room... where?

Because you want privacy when you want to pee at night from the bedroom to the bathroom. And a staircase is the main traffic area in a single-family house.
I would simply swap the staircase and the toilet...

Then she should either avoid the kitchen or you should just make a kitchenette and order delivery service ;)

... and once again not oriented - you can't work like that!

do you really think that will work? I know the market in PL quite well. Prices there have also exploded. For about 500,000 PLN (Polish currency) you can get a small house to renovate. Sure... you would have double that... but for that scale?
Where exactly are you building? You can’t get 6000m2 just anywhere

a slope approximately 30 cm lower

At the moment we have our bed under a slope approximately 30 cm lower and there is no way to hit your head there. ;)
