Single-family house Bauhaus style/flat roof, 2 full floors + basement

Well, aesthetics are naturally a matter of taste, but what I can say is: the cost estimate from the architect could, if at all, only be correct for the cheapest spot in Germany. If it heads towards the south, then a nice sum is missing. Garden and kitchen etc. are additional costs anyway, that's clear. But that's often the case nowadays.

Our property is located in northern Germany. The cost planning refers exclusively to the house. We are aware that outdoor facilities and furnishings incur additional costs. For that, we have budgeted an extra €100,000.

Probably more on other aspects later, but at first glance it is noticeable that this is a more than justified question:

How much space do you have for maneuvering in front of the garage?

The gate and driveway appear to me as architectural misplanning of the absolute highest order.

Basically not so bad ;) ... you will always find a few hairs or even tufts of hair ;).

I think the thing with the bathrooms is a bad idea ... with 2 air spaces you can also retrofit a home lift in case of frailty in old age. Certainly more practical than a stairlift.

Unfortunately, the drawings have no measurements .. the children's room looks very subordinate.

The kitchen looks relatively narrow for the drawn solution approach.

Otherwise, much has already been written by the previous reviewers.

We have not yet received a plan with concrete measurements, but the architect still wants to send it to us. Basically, the scale is 1:100. Due to the arrangement of the air spaces, I don't think an elevator could be installed there. A stairlift would certainly be the simpler option.

The children's room is not directly subordinate, but currently we have no child and we think that almost 16 sqm should be sufficient and the room also offers the possibility later to accommodate a double bed in terms of layout.

What exactly do you consider to be a bad idea about the two bathrooms? Unfortunately, you did not write anything more specific about that.

I like a lot and dislike little. I didn’t look at the basement and have already mentally crossed it out because of the costs. The house would also work without it.

Your child will feel every time like they are only tolerated in the parents’ wing. It IS after all a parents’ wing, also real in 3D – and honestly: if suddenly my child’s boyfriend/girlfriend is standing in the dressing room, I actually don’t want that. That is too “close.” Also fundamentally and therefore poorly planned. Everything else is so great, but that is a big disappointment!
Another disappointment for me would be the orientation of the common rooms away from the south. Especially in recent weeks, I have noticed again and again: south-facing windows are immensely important during the dark season – in everyday life, when working during the day, and in general. I would never think of separating the house from this side with the garage. In your case, additionally the utility room is placed in front as a light shield. That is not a big deal in midsummer, but this is not a summer-only house; it will also be lived in from October to Easter.

Regarding the house/floor plan:
Nice guest room, good zoning, nice flow of rooms. I would realize the cut area kitchen/hallway differently: completely remove the partition wall there and include the area above the storage room to the storage room with an access door towards the kitchen. Then there is still a wall for a console and the kitchen appears more spacious and also gets some sun through the entrance.
The shower will not work in old age, as already mentioned. And if, then the partition wall should be moved to the other shower side; that makes more sense workflow-wise and because of the window.
Similarly in the upstairs bathroom: the shower there is smaller than the toilet area; make the shower longer there, otherwise the T makes no sense.
The bathroom door, as already said, makes more sense opposite the stairs.
Corner windows in the bedroom can cause “restlessness.” I already find it uncomfortable just looking at it.
Two air spaces and the children’s room in between generally means sleeplessness upstairs again. Sound somehow always goes upwards there.
From the outside, the house looks too boxy to me. The front air space on the upper floor should definitely be omitted as a room so that the exterior view benefits.
I am convinced that if it is built like this and a child comes, the child will get the guest room on the ground floor at the latest when starting school.

Either a family bathroom upstairs or a parents and children’s bathroom. From when should the child go downstairs for the toilet, brushing teeth, etc.
Also consider that the child will soon live downstairs.

The dining area could be narrow. You need to measure it.
