Would you like to explain what your intentions are with this?
And could you please upload the floor plans in better quality? Important dimensions are not readable.

I see complications with approval under Section 34.
In principle, I don't find the exterior design bad. Specialists can certainly judge the floor plan.
Depending on the execution, the construction costs are underestimated. Today, I wouldn’t build without controlled residential ventilation.
I wouldn’t call it Bauhaus yet. It’s more cubist with a flat roof.

Regarding the design: at first glance, I liked the basic concept.
However, the kitchen will be very dark, and when guests are over, it will be difficult to move freely in the kitchen alcove. It also won’t be easy for two people to work there simultaneously. Where are the refrigerator and oven located?
The flow of many daily tasks seems quite complicated and not smooth here. Definitely not smooth at all.
The staircase looks very steep or short to me.
There is fundamentally no storage space. The limited 7sqm (75 sq ft) is only enough for a shelf with tools, light bulbs, and cleaning supplies.
I don’t see any space for drying easy-care laundry, beverage crates, decorative items, mop buckets, recycling bags, or an ironing board. (All placeholders for many things)
Unfortunately, the questionnaire is not filled out regarding the number of people and their preferences or needs. One can see the current situation, but the target situation is unknown.
Since everything is pinned in posts, I’ll save links and further explanations.

Basically quite good, but everything is way too small. 170m2 (1830 sq ft) and Bauhaus style don’t really fit together. I think adding 50m2 (540 sq ft) more would make everything feel much more spacious.

Having an office in the hallway is the biggest distraction during video conferences,
how many people are there in total?
We are 5 in total, 2 adults, 3 children

By "design phase 3" do you mean service phase 3 according to HOAI, so you’re still before the building permit / planning permission stage?
Yes

Just a detailed question: are those terrace doors shown as parallel sliding-tilt doors?
No, only sliding

Planning such a bulky building in an established residential area,
expect a rejection from the authorities, it doesn’t fit the neighborhood

We took inspiration from (see attachment), and we liked this design very much:

Also: if everyone builds like the surrounding houses from the 1930s,
there would hardly be any modern buildings:

And I consider the construction costs set too low... interior doors are too cheap and so are the windows... do you have concrete offers for those and also for the Resopal cladding?

Our planner based the estimates on experience from current projects.

Ground floor plan: kitchen, dining, living, bathroom, garage, and terrace.


Upper floor plan: bathroom, office, gallery, bedroom, children’s rooms I-III, stairs.


Modern two-story, white new build with large windows, terrace, and garden furniture.

But the kitchen will be very dark, and when guests are over, it becomes difficult to access the kitchen nook easily. Working there with two people won’t be easy either. Where are the refrigerator and oven located?
The workflow for many daily tasks seems quite complicated here—not smooth at all. Definitely not smooth.

Thanks, I will think about that some more.

All of that will go into the large garage ;-)
