Some building services technology (heat pump, hot water storage, inverter, battery storage, etc.) comes with requirements regarding how much distance is required to the next object. The device dimensions alone do not determine the space requirements as in a kitchen.
Especially since with the current plan, the passageway to the outside means that about 2.5 sqm of the room are no longer part of the room, but rather a hallway, thus also restricting the space.
In what way would a different staircase make the kitchen bigger? Can you give me an example? Due to the quarter turn, the hallway would become wider, so the kitchen would become even narrower.
Yes, especially since the straight staircase is not very generously planned either. The kitchen is on the smallest space and with the current trend of a "passage in the tall cabinet wall," there is little space between the cooktop and the sink, and with a room depth of 288, there is also little room for variation. Especially if you sometimes want to cook with children and be able to turn around.

Years ago, I sketched a similarly sized house that, in my opinion, could fit somewhat better. With the room program, it is important to have precise planning. This example has "only" 849 cm external dimension... the 861 (15 cm more), which the original poster has, would also benefit this example.
Technical room - door can also open into the hallway.
Stairs - space under the stairs for a pantry cupboard and vacuum cleaner/mop
Office and emergency guest room on the ground floor
200 cm cloakroom space
Kitchen with sufficient space
Sofa corner arranged so that you can also look out of the windows.
The room called "dressing room" can be used for washing machine, upstairs vacuum cleaner/mop, etc. But also for suitcases, certain seasonal items of the whole family, etc.
The staircase itself could also be continued into an attic... I don’t remember if this question appeared here in the thread.
