Large, dark, uninviting entrance area / hallway. 22% of the living space.
The darkness could be solved by a window near the stairs, but the entrance area won’t really get better, only a bit brighter.
The kitchen/dining area and the "living square" are basically fixed, and for the rest, attempts are made to create a good floor plan by moving walls. That doesn't work because you always end up in the same dead end.
The access to the terrace behind the stove is inconvenient (it always was, but I only noticed it now).
The guest WC was "disappeared"?:rolleyes:
