Floor plan tips for a single-family house with a desired granny flat

The building application has already been submitted. Unfortunately, uncertainties regarding the floor plan have crept in during the eight months of waiting for the building permit. We will not be able to change the exterior dimensions anymore, but the floor plan inside is not coherent.

Hello everyone,

We already have a finished floor plan for our single-family house with a granny flat. The building application has already been submitted. Unfortunately, during the now eight-month waiting period for the building permit, uncertainties regarding the floor plan have crept in. We will no longer be able to change the exterior dimensions, but the floor plan inside is not quite right.
A brief note about the granny flat: it is intended for my parents. They will partly live here and partly abroad. The idea that they access the granny flat through our apartment is not desired. It should remain with a separate entrance. Even though it is annoying that we have two staircases. Later the apartment could serve our son when he is older, or it could be converted into a hobby room, or whatever...

On the ground floor, I would much prefer to have the kitchen where the living room currently is, including a kitchen island. The problem is that the living room would then have to move to where the kitchen is now, and with 3.13 m that would be much too narrow.

On the upper floor, a small storage room could be created after the stairway to accommodate the washing machine and dryer.

Additional wishes/special features/daily routine, also reasons why this or that should or should not be
Swapping the living room and kitchen would have the advantage that you could talk on the couch in the evening without it being too loud upstairs (because of the open space)

House design
Who created the design: the design comes from our architect, but the plan is not quite right.
What do you particularly like? Why? Well, not much
What do you not like? Why? Living and dining area and kitchen are overall too narrow.
Price estimate according to architect/designer: 450,000
Personal price limit for the house, including equipment: 510,000
Preferred heating technology: air-water heat pump

If you have to give up, which details/upgrades
-you can give up: floor-to-ceiling windows on the upper floor
-you cannot give up: straight staircase and the open space I would also prefer not to give up

Why did the design turn out like it is now?
This is the third design of our planner, which we also liked. Now we are unsure.
Number of rooms and open space and straight staircase would be considered.
What makes it particularly good or bad in your eyes?
The space in the living/dining area is too small, or rather the room is too narrow.

What is the most important/fundamental question about the floor plan summarized in 130 characters?
Development plan/restrictions

1. Would it make sense to swap the living room and kitchen? The future living room would need to be made wider, as 3.13 m is not enough.
2. Could a storage room be planned on the upper floor? Possibly after the stairway.
3. What do you like or dislike?

I am very grateful for suggestions and tips.

Best regards
Nicole

In the upper floor, one could create a small storage room after the staircase landing to accommodate the washing machine and dryer.

Swapping the living room and kitchen would have the advantage that you can talk on the couch in the evening without it getting too loud upstairs (because of the air space).

but the plan is not round.
