I find the whole draft still very unpolished.
As my predecessors have already pointed out: you are wasting an incredible amount of space on the upper floor with the gallery and the air space. If you absolutely want that, then (let me also apply my favorite saying here: man’s will is his kingdom) go ahead. It doesn’t make sense. If it were part of an overall harmonious concept, I might be able to like it more, but unfortunately that is not the case here either.
My comments:
The angled layout has already been mentioned. What I don’t understand at all are the countless corners and niches in the exterior wall, e.g. the ground floor top right? What is this niche supposed to be??? And on the upper floor, it is then built over??? Apart from the fact that such (unnecessary) frills cost a lot of money and are more than questionable from an energy perspective, what is the purpose?
Personally, I am a fan of going directly from the garage into the pantry, but your solution here is pointless. This airlock (that’s all it is) is useless. I would rather put a door from the niche (again, one more!!!) in the garage to the obviously covered entrance area. If this storage room is supposed to have any use at all, then please remove the door to the garage. Even then it is almost too small and at best only usable for some cleaning supplies. If it is supposed to serve as a pantry, then it would make sense to plan something like that near the kitchen.
Terrace niche (you really have a thing for niches, don’t you?), all well and good, but a terrace facing north? And then in a niche? That will be more cool and damp than sunny and warm. Makes little sense. I know a family in our village who renovated and rebuilt an old house and really had no choice but to put the terrace on the north side. They now have a nice, large terrace with a fireplace and all sorts of gimmicks... but they always sit out front on the south side of the house because it’s always too cool in the back except in the dog days of summer. They have about 10 sqm of lawn there, the old gazebo, and now camping tables and chairs.
Currently the garage is on the south side. Do you have a requirement that the garage must be placed there? Otherwise put it on the northwest side. Guest room where the kitchen is now, then the kitchen. I would then remove the terrace niche and put the terrace on the southeast/southwest side. I don’t know how busy the road is, but maybe you can really move the terrace in the front to also catch the evening sun. Privacy protection doesn’t come only through niches, but also maybe through hedges or privacy fences.
Basically, I would sit down and start by roughly distributing the functional rooms. And in a way that makes sense. At the moment you have the "living" on the ground floor in the northeast. That doesn’t make sense to me.
I scribbled a bit how I would think about it. I’ll post it. As I said, it was just scribbled on a scrap paper to figure out how best to position the house. If I’m reading it correctly, you have a rather elongated plot, right? The plan is also correctly oriented with north at the top?
Then generally, one could consider placing the garage as close as possible to the street, namely on the left (NW), and move the house a good distance back. Advantage: I would still have a lot of garden to the southwest (the street side, if I interpret that correctly). As it is now, you have a lot of garden to the northeast. Nice for someone who likes cultivating moss, but otherwise you’d rather have a sunny garden, right? Look at my second draft, maybe push the house even further back.
Enough has been said about the layout on the upper floor. I would consider making a small second bathroom out of the utility room. That has advantages when the kids get older.
If you restructure the downstairs as I planned in my second suggestion, you could also roof the terrace here. For example, with a green roofed porch. You will hardly ever use a balcony upstairs if you have a big garden downstairs. A green roof porch can be walked on and you could put a clothes dryer on it. That’s all you need and you can save yourself a balcony railing. Then put the bedroom in the corner where the utility room is now, the dressing room as well, and the bathroom in the east corner (where the bedroom is now), then move the utility room above the guest room on the ground floor, children’s room in the southwest. That would be my layout.
Then plan details like the staircase (where to, which shape) and if absolutely necessary: gallery, air space.
But first I would define the functional rooms sensibly and definitely (if permitted) put the garage on the other side.
