I have to be honest: two important elements in a house like a staircase and a kitchen unit, which are both supposed to stand on their own - in a house that can afford it, so not 109 sqm designed for 4 people - must not have any points of contact, must never merge, nor be built over or under each other. A landing staircase can be so beautiful - without kitchen cabinets underneath - they have no place there. How should the staircase be executed there? With a wall or open? I see it as open. Dust falls with every trip to the kitchen. The room is full of unrest. And you don’t have to see the steps of the staircase in a kitchen unit either. You can do that in a semi-detached house, or when the floor area ratio is too low, so a cost-saving measure. Or in existing buildings like an old farmhouse, where nothing else works. But like this?!... hmm.
