Floor plan design single-family house approx. 240 sqm with double garage and basement apartment

Could it be that BOTH clients are humanities scholars, and the architect is from the circle of friends and not much older either? I don't see any tea in the world capable of making the delta between the wish list and the budget look better. A professional has to step in here, who first does brutal homework.

Additionally, the outdoor area does not necessarily look favorable, with a long driveway and paths to the entrance, a small courtyard for the basement apartment with L-blocks(?).

I find the basement apartment as a "residence for old age" very dark, additionally not practical due to all the stairs, access only possible from outside.

Currently, you have 4 "offices," of which 2 would later be for children, plus a large basement of 35m² plus the entire basement apartment, as a space not used directly or only partially with a good but not unlimited budget. Additionally, for storage, technology, utility room on the ground floor, and in my opinion a very narrow but generous (sqm) pantry. (Too?) Narrow dressing room was already mentioned, >2.2m is recommended. The wardrobe in the hallway is quite tight with the one closet, I suspect extended would be in the utility room?

I am also in favor of removing the basement. Financially not possible. Condominium for the care of a parent is maximally inconvenient. Stairs and separate living unit. The ground floor study will probably be used for that instead. With 2-3 children + care someone will have to quit their job anyway. Move the house a good bit towards the street.

Hello,
thanks for the many constructive questions and suggestions that made us think :)
I was surprised by the tone in some posts, but that seems to be common in this forum. We were able to revise our plans with the result: apartment removed, room upstairs removed and instead of a full basement only a partial basement. Plus a clear message to the architect about the budget.

Thanks

and instead of full only a partial basement.

Better include a separate study or guest room or something similar instead of the granny flat; partial basements are often mostly economically disappointing.
