Don't let yourself be too unsettled. Arguments like "such a house needs a straight staircase" or "the lots of glass looks like a car dealership" only show that it's not about content, but that a residential house apparently must have a gable roof. If you want to build this style, in my opinion you have achieved a successful exterior look. But I could imagine not making the accents in this grey, I'm not a fan of that. How about a mix of materials, maybe a bit of wood on the facade? The exterior design also contributes a lot to the perception of the house, which is of course very hard to imagine in the presentation form because the house now stands on a huge, empty plane in the graphic. The neighborhood will reveal quite a bit.
Your sleeping area is unnecessarily large. If you have lots of clothes and a cross trainer, put that in the basement, that's exactly what it's good for. Nobody needs a 9m wardrobe full of clothes for regular selection, right?
Don't like spiral stairs. Is there no landing possible there?
You had rejected suggestions here because something wouldn't be as nice for guests anymore. Here's a tip: clarify priorities. Think about the fact that your guest room costs over €30,000 — you could stay in a hotel for a long time for that. Besides, the room is considerably larger than your children's rooms, which is kind of off. Unless you expect the Queen on weekends, I would reconsider. Priorities.
I also find it a bit strange to argue about costs for the small children's rooms when you have such a palace with lots of unnecessarily large space on the table.
In the large upstairs hallway, if it remains, a skylight belongs in the roof. If you're already building flat, you should also take this unique opportunity there in my opinion.
Thanks for the idea with the skylight! That is really brilliant, I definitely have to include that.
I also like the staircase landing. But the width stays as it is. I measured my parents’ staircase again over the weekend. It is 50 cm smaller and even that would actually be sufficient. To be honest, no one would even notice when walking through the house.
The kitchen stays as it is too, there will only be one door to the hallway because otherwise you have to walk through the living room. However, the terrace will be extended towards the east because the actual garden area is located there. (You can see that in the overview I posted.)
Otherwise, regarding things like cross trainers in the basement—have you guys actually ever used such a thing? That is extremely boring without a TV. I don’t think anyone would be keen to stand on that thing for half an hour in a bare basement room.
Sorry, but which child has/needs a 1.4m wide bed??? I used to sleep with my then girlfriend on 80 cm. One meter would have been a luxury.
