I understand that you want to create something unusual. However, if you are going to ask
Gibt es sonst vielleicht noch etwas, was gestalterisch Blödsinn ist oder vergessen wurde?
also read the answers sometimes and try to understand.
I have asked you some questions, those are already points of criticism, but you can work those out yourself. My questions are actually just a direct indication that this design has not been properly thought through.
For example:
Wir haben uns bewusst gegen eine zweite Dusche entschieden,
Now I can explain as a fourth forum member that a) it is not exactly "nice" for children to dash to the bathroom past the main doors, b) teenagers will block the bathroom or the shower at the latest. But I will not do that.
I do want to point out to you that you can see from the dining table into the WC when, pardon, the double door is open.
Warum ist das Schlafzimmer ein Durchgangszimmer?
That question I
asked you :) It is not peaceful when every morning one person is disturbed by the other's light and bustling around. Now you will probably say that it has always worked until now and you have
consciously decided for it.... ;)
Mit dem Stauraum haben wir auch überlegt, aber entschieden, dass der Dachboden und Außengebäude reichen müssen.
Washing and drying laundry? Children's toys/cart/sports equipment? Nowadays the heating already takes up quite a few square meters. ...
Büro: Familiennutzung
Don’t you need something like that? Maybe later?
With 500,000 you can build yourselves a stately house. Congratulations. However, at the moment I do not see that the Y even comes into its own from the inside. I think that when you actually live in 3D, this endlessly long corridor wall, which is also visible in the open-plan room, is an eyesore and detracts from the spatial effect. It is not beautiful. Also, the small little bit of living area is confusing and does not fit the rest of the room. The proportions are off not only in this room. Although there is a field to the north, I do miss a bit more sun in the individual rooms. The Y-shape probably does not make the building very energy-friendly either, plus the missing south-facing windows, too much north-facing surface... that could be tight. The delicate balance of harmonizing energy, sun, and view, I do not see here.
I have also seen the Y from a known general contractor, unfortunately, I can’t remember who is building it. But you should be aware that with such a terrace you have a rather freer terrace since the open-plan room with three sides faces outward rather than the other way around. You should keep in mind that any possible roofing of this would break the symmetry again.
If Y, then check every detail mentioned here to see whether it makes sense – not only today but also in 10 years with grown-up children... because the interior planning is not really a plan, too much is missing: reasonable wardrobe, cozy seating area, kitchen island near the dining table, storage and surface area, laundry area, and sunlight. Seeing a field from all rooms will get boring eventually.
What sounds very good is the open-to-above open-plan room with the window front. But I would rather plan that facing the garden rather than slanting away, since the sloped roof already emphasizes the building a lot – sharp or obtuse angles in the house's structure are really too much of a good thing! Free gables with lots of glass in the gable roof – there are plenty of examples where the glass wall really comes into its own.
