House planning for 3 generations

Why is such a convoluted design, including the building envelope, being constructed?
A courtyard may be nice, but this one will never see the sun and will therefore decay.

If I now look at the wardrobe/pantry complex separately in the main building, I don’t understand why this complex isn’t divided the other way round so that you get two well-furnishable rectangular rooms and not two tubes as it is now.
You could also swap the rooms in the northeast and thus have the utility rooms in the north, then a shorter corridor that ends with an office and then the living room. Shorter corridor = more usable living space.

Similarly, in this building envelope, there are more possibilities in grandma’s apartment if you simply place the bathroom door in the hallway and shorten this again. Kitchen in the north (top of the plan) results in a generous kitchen unit and more flexibility in furnishing.

But everything is really very, very convoluted... this large roof terrace is also inexplicable. You first have to make this large area watertight. The roof terrace itself will be a major cost factor. The constellation is not that simple: the roof needs a slope, then there has to be wood on it at ground level. A lot has to be calculated and installed on this area.
Regarding the budget: I also don’t see 360/80 thousand.

About your roof concerns: why don’t you build the main house as a two-story building with a gabled roof? Grandma’s apartment mathematically makes the building a single-story...

Wishes/Special features/Daily routine:
Main house ground floor:
Pantry and cloakroom are to stay there and are planned exactly according to my needs and ideas.
Opposite the pantry comes the family info wall (1.50 m wide)
Sleeping is deliberately small and facing northeast.
Utility room is the laundry room with access to the drying area.
The office is exactly at the height of the driveway to the yard and thus always in view during work.
Main house upper floor:
Sleeping here is also intentionally only the bed (200x220) large and with drywall still a partition to the wardrobes (no dressing room).
Child 1 has the wardrobe directly opposite the door (so one does not have to go through the whole room and there is no toy blocking the wardrobe) and to the left then his quiet area, the rear part is the play area.
Child 2 is the granny flat with its own kitchenette and bathroom, the room itself can be furnished as desired, the bed fits in all corners of the room. The entrance is possible through the house and via the terrace (if he ever has to move out, it can be rented better this way).
Age-appropriate extension:
The bathroom can be accessed from the hallway and from the bedroom.
The bedroom window faces west.
In the living and kitchen areas, the windows have a sill height of approx. 50 cm.

On the upper floor there is currently a knee wall of 1.80 m, but the knee wall windows cannot be opened (I find a fall protection unattractive) and I would also like shutters here. But then the window would only be 60 cm high... I just can’t imagine how that looks.
Price estimate according to the architect: €380,000, we have construction costs of just under €1,200/sqm here. We are also building without a developer, meaning no salespeople earn money with us. Since we can do quite a lot ourselves, in some areas only material costs are incurred (and even here we have very good conditions). Also, some costs do not apply to us, such as an extra construction power connection, a toilet only for the workers is available, scaffolding for erection is available, excavator and wheel loader are on the yard.

Subcontracting will be for: foundation slab, shell construction, windows, and roof (only the roof tiles we will lay ourselves again).

On the area where a house is now being built, there was recently still a stable building (demolition costs for customers around €30,000 – my costs = time, fuel (€300); disposal (€3,000) and two barbecue evenings).

Site plan, north arrow, floor plan dimensions, etc. are missing.

Still ;) (although I just discovered a small text on the ground floor.... too bad that plans can’t be posted either with a clearly visible north arrow or at least oriented to the north). The location on the plot would still be interesting though. Repeating the other points wasn’t so relevant ;) and doesn’t make the sleeping/closet area layout on the upper floor any more appealing ;).

Wardrobe argument for child 1.. well .. then child 1 stands by the wardrobe looking for clothes (100 to 120 cm is also .. well quite tight) and then mom opens the door and she ends up right behind.

Everything about the knee wall height has been said, either accept it as is or convert to a full story ;). What kind of suggestions are you expecting? And, what are you generally expecting from this thread now?

Thanks, that’s exactly a criticism I hadn’t thought of! I need to think about that again!

Unfortunately, we are not allowed to have a full story. And they are actually only supposed to bring a little light into the room.

with clearly visible north arrow or at least aligned to the north otherwise).

Unfortunately, I only took the two prints with me, so I don’t have any others available.

My photos are unfortunately too large to upload.

I don't understand this thread: are the answers not being read, instead the original post (incompletely filled out questionnaire) is being reposted?!

If you ever want to rent out the granny flat, you should look at it through the eyes of a tenant and not through the eyes of your adult son who still wants to comfortably return to the family fold. The granny flat you have planned is really terrible for an outsider to live in. Always make a realistic plan for it.

Otherwise ... no site plan available where you could sketch the house location?

No measurements of the house at all? Unfortunately, you can't rely on furniture drawings by architects as an approximate scale because they tend to be drawn much too small. And I really find it difficult to assess the practicality of a house without visible measurements.
