House and floor plan planning - First architect's plan is available

As announced some time ago, our old house in Baden-Württemberg has now been sold, our move to the Leipzig district completed, and we can now focus concretely on our new house. Due to our age, we have consciously downsized in terms of plot size and living space. An initial architectural plan is available. I have already noted a few change requests and am now looking forward to your additions, criticism, and suggestions. If further plans or similar are needed, I will gladly provide them as far as they are available to me.

Thank you in advance for taking the time to help me.

House design
Who created the plan:
- Builder company planner: yes, in combination with the builder
- Architect: unclear
- Do-it-yourself: yes, in combination with planner of the prefab house manufacturer
What do you particularly like? Why? Many windows and patio doors, lots of daylight and air
What do you dislike? Why? In the plan, the windows on the upper floor are too low, but this will be changed
Price estimate according to architect/planner: already commissioned offer/order 312,780.00 euros (without carport, outdoor facilities, ancillary building costs, land, ...)
Personal price limit for the house, incl. equipment: 400,000.00 euros
Preferred heating technology: gas condensing boiler plus solar thermal (according to legal requirements)

If you have to give up, which details/extensions
- can you give up: we already give up shutters, whirlpool
- can you not give up: many windows and patio doors, muntins in the windows and doors

Why has the design turned out as it is now? e.g.
A mix of many examples from various magazines...
What makes it particularly good or bad in your eyes? It corresponds largely to our wishes. We want to be able to step into the garden from every room on the ground floor. We find symmetry more pleasing than asymmetry. Few different window and door formats. No "horizontal" windows. Each of us has our own room for, among other things, clothing, so that we do not have to place a wardrobe in the bedroom. We do not want a separate dressing room.

What is the most important/fundamental question about the floor plan summarized in 130 characters?
The roof seems somewhat steep to me. Is 30 degrees roof pitch too steep for a house with a base of 9.40 sqm x 9.40 sqm? The standard according to the provider for this house is 22 degrees. That seemed too flat to me, or you can hardly see the roof.

The development plan was too large to upload; I will try again in a separate post in this thread.

The second attempt to upload the development plan has failed. The development plan is too large.

Thanks in advance for taking the time to help me.

Later gladly, at 8:30 p.m. Babylon Berlin is on, and I still have to cook before. At first glance, I see a lot of inspiration from symmetry princess Shiny86 and wonder about the binder roof at this pitch.

The second attempt to upload the development plan failed. The development plan is too large.

Email me that thing (classic, not via private message) in all the formats you have and wanted to upload (and in this way also without problems with a link to the source), then we should be able to get hold of the good piece.

Hello,
a few things occurred to me spontaneously that I have questions about:
- The shower on the upper floor seems quite small to me, but maybe it just looks that way next to the large sauna?
Is there a lounge chair marked in the bathroom? Some bathtub manufacturers offer pads for the bathtub to turn it into a lounge. Not cheap, but very stylish (in my opinion) and you could save the lounge chair that is a bit in the way.
- How is the kitchen planned? It's a shame you don't want it open; you could also separate it, for example, with sliding doors. I find the path to the dining table and terrace very long.
- Why a shower on the ground floor?
- Wouldn't doing laundry on the upper floor be more practical? Especially as you get older, it can be difficult or even dangerous to carry the laundry basket up and down the stairs.

Hello, I would not place the carport in the south. Double carport in the north. What are the setback areas? Aren't they also 3m in Sachsen? Then move the house 80 cm to the north. Why build a square there? A rectangle with the long side in the south brings more freedom on the south side. INAA

Hello, the house definitely has plenty of space for 2! One idea would be to swap the bedroom and office 1, then the way to the bathroom is not so far. Otherwise, has given good tips. Above all, the missing passage from the kitchen to the dining room stands out.
