Single-family house approx. 155 sqm - edge of field location - experiences, ideas?

I still see some issues:
- Dining area too tight
- Cloakroom completely missing
- Technical + utility room much too small
- Pantry door disrupts the kitchen front awkwardly
- Bathroom access upstairs only through private dressing room – guests have to go downstairs?
- Sauna should preferably be next to the bathroom or even better integrated directly
- Access through the technical room is 2m next to the front door – that’s nonsense. Better: house entrance canopy
- The garage driveway is too close to the platform. When parking a second car, you regularly scrape the tire along the platform.

In your place, I would consider moving the technical room upstairs. You have rooms left there, which you are already worried you won’t be able to use. For that, I would add a cloakroom downstairs, relocate the WC and pantry, and widen the kitchen (I would extend it to the full width of the bay window, but that also depends on the kitchen design). This creates plenty of space for a large, beautiful dining table as a central element when the children come.

I would move the fireplace into the hallway, and here I would also partition off a storage room that includes the space under the stairs. This way, only the glass fronts of the fireplace are in the living room.

On the upper floor, I create access to the bathroom for my guests. Moving the door also creates more space in my dressing room. The sauna is integrated into the bathroom (replan the bathroom layout!). I use the guest room as a studio when my guests are out of the house.

This is sketched here in a quick draft – so there is surely room for fine-tuning:

That looks good, Katja, but I think if he had wanted to omit a guest room, the floor plan would have been different from the start...

Exactly.

If you need 2 guest rooms at the same time, I would rather consider separating the workroom downstairs accordingly + adding a shower to the toilet.

.. Katja, at the moment one room is still missing - right? For the future, I would also rather plan the sauna in the room next to the bathroom in the current plan. And have a breakthrough prepared there at the same time.

As I said, they are two and have the children as guests, if I understood correctly. So I would plan a large guest room upstairs (for 2 children) and downstairs the study room optionally as a second guest room with a shower in the guest WC. I would use the guest room upstairs as a studio when the children are gone and downstairs again as a study room. Much more important in the future will be the large dining table where 12 people can quickly have a place, because when the children are older, they hardly stay overnight anymore, but they like to come for meals.

when the regular visits become less frequent and not all at the same time anymore...

we don’t play there - rather play "board games" at the table

Maybe the visits will even increase later if there is a computer room

We thought it was practical to have a door into the garage - [...] - and then you don’t always want to open a 5m gate when you want to get something...

That is a sensible thought, not to have to open an entire garage wall for every little thing.
