House design
Who designed the plan: myself
-Planner freelance architect
-Architect first appointment with the architect has taken place, concept available (see pictures)
-Do-it-yourself no, turnkey contract, possibly individual trades subcontracted or own work done or trades subcontracted individually
What do you particularly like? Why? south-facing slope location with view
What do you not like? Why? size of the plot somewhat small, but no alternative
Price estimate according to architect/planner: 2000 €/m2 living area, plot 83,000 €
Personal price limit for the house, incl. equipment: 600,000 € (without plot)
Preferred heating technology: n.a.

If you have to do without, on which details/extensions
-you can do without: garden pool
-you cannot do without: double garage with superimposed terrace

Why is the design the way it is now? Because it corresponds to the wishes and fits the plot
Standard design from the planner? No! Individually planned
Which wishes were implemented by the architect? Double garage with superimposed roof terrace

What do you think about it or are there suggestions for improvement?

Stylish house from the outside ... but not even a broom closet on the ground floor - let alone a cloakroom

The children's room is smaller than the dressing room... wow!
Highly impressive for a custom design.

Positive ... all important information in the first post ... that has to be highlighted because unfortunately it often doesn't work out that way. So already *thumbs up*
----------------------------------
The children's room also caught my attention ... together with knee wall height and 2-meter line not a very nice room.

I would also be interested in the planning of the bathroom upstairs.

Dressing room and master bedroom with south orientation ... hmm, especially the bedroom .. bed position? Dressing room, the window width with wall sections on the right and left, which look less than 65 cm, stand out.

I can understand why the entrance is rather on the north side, but visitors don't have it easy there.

Where is a garden pool supposed to go? Wouldn't it be good if it were accessible via the fitness room?

In general, I miss the intended furnishing.

Yes, almost ... (History)

In general, I miss the intended furnishing.

I feel the same way. Especially living room-kitchen with at least 66 sqm "empty" is a bit abstract to imagine. In the garage, the door could hit the support pillar (which, however, is at least standing where the drive is most conveniently placed). I’m picking up the mantra of my suggestion here, to think about single doors with goodwill.

I don’t quite understand the thing with the entrance either.
Guests would probably park in front of your garage first. Then they’re allowed to go back onto the street and walk up to the entrance? I find that unfortunate.

I find the entrance area generous, but because of the doors close to the walls (front door and access to the dining room), it’s not really easy to place a coat rack.
I wanted to say you could put it under the stairs, but that doesn’t work because of the basement either.
So either a coat rack is placed in the stairwell, in which case you can forget about having an inviting entrance area, or on the wall facing the living room, but somehow it doesn’t fit there either.

I would slide the door to the guest room downward, flush with the stairs.
The small square anteroom is of no use to the hallway at all; if you add it to the guest room, at least the door won’t be so much in the way when furnishing the room.

I also find that this huge ground floor lacks a broom closet/storage room or something like that. Overall, to me it’s just big.
The kitchen is as far away from the entrance as possible (no matter whether the entrance is in the basement or the front door on the ground floor).
But it’s also far from the terrace.
I would seriously consider swapping the living area with the kitchen here.
Then you could place a storage room north of the kitchen near the entrance. Then you’d have a door from the kitchen to the hallway, as well as a door to the terrace.

Upstairs, I don’t understand the priorities.
The dressing room gets the prime spot, and the child gets the north side and not even 13 m². For a house with 250 m² that’s a statement. Would swapping the office and the child room not be an option?
How often is the office really used by you?
What’s the point of the 16 m² indoor pool anyway?

I imagine the bedroom to be quite cramped. The double bed combined with the sloping roof should cause problems given the room size.

Sorry, no offense, but it wouldn’t be mine at all.
For a house this size, I expect it not to be cramped anywhere.
Here, savings are made in the wrong places (no storage possibility on the ground floor, coat rack, bedroom, kids’ room) and extravagance at the wrong places.
The staircase alone has over 40 m² (!) and that doesn’t even include the gallery.

I think you could easily reduce the house by 30–40 m² without really noticing it.

Given your budget, that probably wouldn’t be the worst idea either. With a house of this size, you probably also have different expectations than just a basic setup; with the slope, roof terrace, basement, double garage, balcony, it’s going to be tight with your budget.

Teenager (16) I would relocate the children's room to the basement (Fitness).

For completed outdoor facilities with pool, easily another 100k+ goes away.
