ᐅ ETICS with concrete construction or exposed concrete?

Just try googling images for "sandwich concrete" to get a basic idea of what it is. It typically costs about 30-50% more per square meter (sqm) net compared to your option.

Won’t the hallway and entrance area be a bit dark? The bedroom window is just above ground level, so you might as well make it a patio door. Do you really want the bedroom and bathroom to open directly onto the terrace? I would move the living room and kitchen to the basement, then you wouldn’t need the small kitchen down there. In any case, with the current design your elevator should be closer to the small kitchen in the basement.

Seems like a typical architect-designed house. Interesting to look at, but maybe difficult to live in... Your house is less than twice as wide as the garage. I find the proportions problematic because it emphasizes the garage too much.

To clarify: The bedroom window location is not final yet – it can be changed easily. It was different before because there was a balcony on the south side, which we didn’t want. The bedroom originally had a corner window like on the ground floor, but that is no longer feasible because of the terrace. The small kitchen is deliberately intended for me because I need an extra fridge and workspace for BBQ preparation – I prepare a lot of meat for smoking/grilling, and I also sharpen knives with whetstones here – so this was a specific wish and has to stay as planned. The elevator does not exist yet – only a shaft space is planned here. The area is fully usable, but it allows for the option to install an elevator later in case of limited mobility (not wheelchair-bound), which costs nothing upfront. Bathroom / dressing area: This will become a kind of glass niche to allow views outside and enhance the sense of space (to the south there is nothing but our land and a tree line – no neighbors or anything else, just a view!). This is actually what we want. The width of the garage cannot be changed – whether the proportions are right or not, there’s no alternative. The plot is simply not wider, and actually I find the garage even too narrow...

But aren’t we back to precast concrete elements here? We already discussed this topic in the other thread, right?!
According to ant1, due to prefabrication with batch size 1, it’s not feasible to achieve realistic prices?!

You can do this using precast elements, cast-in-place concrete, or a combination of both. Since you want concrete on the inside anyway, and you also need insulation, the difference lies in the plaster finish. Plaster costs around €50 per square meter (about $55 per square foot), while a precast panel used as a curtain wall costs roughly €80 per square meter (about $9 per square foot), including mounting.

If the look is important to you, then the additional cost of around €6000 (about $6600) isn’t that significant.

Thousands of builders construct basements using concrete in sandwich panel technique (just take a look at the precast basement manufacturers). In principle, this can also be done above ground.

11m2 (118ft²) for the child and 17m2 (183ft²) for the parents to sleep despite having a walk-in closet? I would prioritize more space for the child and scale back for myself... Why does the bed and sleeping area alone require 17m2 (183ft²)? The child could use that 17m2 (183ft²) much better... I’ll never understand that...
