Regarding the ground floor, that is somewhat due to our wishes.
We wanted direct access from the utility room to the kitchen and the hallway, so that when entering the house through the garage, you don’t have to walk all the way through the kitchen/living room to get to the cloakroom.

We are looking for a solution here. Moving the staircase to the back and placing the entrance to the utility room almost next to the front door is one option.
And where would the cloakroom be? You use the whole hallway around the stairs, which is not practical.

I find the kitchen awkwardly long and therefore not practical.
LR: Sofa is arranged in a cramped way.
Regarding the hallway, utility room, and bathroom, I agree with Katja.
Regarding the bathroom: since part of the bathroom is above the entrance, you have to be very precise and set the wastewater pipes accordingly. They also have to be in the house on the ground floor. They probably should not be in front of the stairs, etc. There are not many options left.
I wouldn’t want to give up the shower on the ground floor with three children.
The conservatory is located on the west side. Most of the wind comes from the west. Therefore, I would move the garage closer to the street and enclose the corner with bushes so that the wind can continue through the leaves and no corner of stagnation (is that what it’s called?) occurs.
A door to the storage room does not look good on the terrace; rather better set it out of sight around the corner.
I would shorten the kitchen, possibly have a preparation island, and behind it, as you wish, the pantry/backup kitchen. The utility room should be accessible from the front and also have wardrobe cabinets for 5 people. Count the number of your jackets and shoes for the entire year.
Position the WC with shower and window so that cabinets can also be placed.
I sketched something here:
... but I also don’t find it ideal – especially regarding the kitchen and cloakroom.
Unfortunately, you cannot just move a staircase by half a meter.
Better to plan anew!
