Hello Notstrom,
I have also been just reading along for a long time and back then I didn’t "dare" to upload my floor plans. The house has now been finished for almost a year and I am very satisfied, although I didn’t seek any opinions. I was really afraid of getting totally confused back then. And I think that is slowly happening to you too, Notstrom. Personally, I find your house quite successful. That is also the reason why I want to step in here before you change the architect. Also because I like cubes, I have built one myself.
To contribute something constructive to the thread again: You say exterior views/windows will come later. I would move away from these classic 2-part "normal" windows and rather install vertical or horizontal windows or equally sized glass fronts like below. It looks more modern and fits the cube better (speaking from my own experience). I like the separated living area, I would just enlarge it a bit so that the passage to the dining room is not so narrow. Move the stairs a bit to the right side of the plan. Delete the storage room (you have a huge basement!), and instead make the wardrobe bigger. I wouldn’t open the stairs to the dining room because it’s always noisy upstairs and food smells rise (despite controlled residential ventilation and extractor hood, just put a lasagna on the table for 20 minutes). Better a large glass door, which also brings a lot of light into the hallway. I would probably move the fireplace as well because of the narrow passage. In my opinion, the living area has too few south-facing windows. Corner glazing would look cool there.
Upstairs, I don’t find the dressing-bedroom-bath area optimal either, although I personally find the bedroom cozy. It is better to have the dressing room between the child and the sleeping area. I would also definitely do without the second bathroom door. It only steals space and saves exactly one door to open and close. But then you have to lock a second door. If you move the stairs to the right side of the plan, changes will happen anyway. The kids’ rooms can become bigger and the bent wall between the two rooms can disappear.
And because it rained through for 12 hours in Bavaria yesterday, I worked my thought processes into your floor plans using Photoshop.
Maybe it will give you some ideas for further discussions with your architect.
P.S. I would definitely not make a separate access from the hallway to the living room. That’s just uncomfortable and takes up space again. Back then, the draftsman wanted to talk me into a passage because you basically have to walk through the kitchen to get to the living room in our house. I’m really glad we didn’t do that and that I ended up with a large, cozy, sheltered sofa corner.
