You can fit everything in, it’s just not a ballroom.
But of course you can also set up an open space on 37sqm. The furniture is just somewhat reduced somewhere. In your case, the kitchen. The question here is whether you accept that for 800K? Mini kitchen and entrance area like in a cheap hotel room?
Why should you use premium living space, which you pay a lot for, for air, to then use less usable space in the attic?
Because it’s nicer? I had the impression that the OP doesn’t need dozens of small or large little rooms, but rather a liberation stroke for the open space.
That neither gains space on the ground floor, nor makes the living area upstairs more livable.
In my opinion exactly that.
Just smaller and with a wow factor that comes at the price of poor acoustics.
Acoustics should be well planned, you’re right about that.
It’s not an architect’s villa, but a single-family house with an integrated double garage, attached to a multi-family house.
And that’s why it absolutely has to remain a small cramped standard house?
