ᐅ Floor Plan: Preliminary Draft from the Prefabricated House Supplier is Available

Hello dear experts!

We now have the 5th preliminary draft from our prefab house provider on the table, and the list of our correction requests is noticeably getting shorter.
It’s time to ask the true experts for their opinions.

We won’t (or can’t) change the basic floor plan concept anymore, as we want/need to submit the building permit/planning application soon. But maybe you still have tips, warnings, or new ideas regarding details.
Secretly, I hope this thing will be approved more or less favorably by you – but many here have hoped the same and were bitterly disappointed.

Important to know:
Child 2 will not have a children’s room but a combined dressing room, storage space, and guest room.
Up to this draft, we had planned a 3.75x1.50m (12.3x4.9 ft) bay window (external dimensions) in the dining area, which we wanted to furnish as a dining nook with built-in seating by a carpenter.
Since we fear the costs might spiral out of control, we wanted to see if and how this could also work without the bay window. The final decision for or against the bay will be made once we know how much savings dropping it would bring. My impression: not super spacious, but it works.

I am particularly interested in your feedback on the following details (besides anything else you might notice):

- Narrow doors for the guest toilet and utility room on the ground floor – problematic or totally okay?
- Staircase: better open for light transparency, or with risers and a front wall so you don’t have to look under the stairs every time you come from the living room? How practical or useless is the storage space under an open staircase (without a front wall) in reality?
- How and exactly where is the best way to design the access to the living room: front / middle? Single or double doors? No door at all, just a wide open passage (also to bring light into the hallway)?
- We chose an extremely wide kitchen layout, partly because with the open floor plan you can basically see from the street all the way to the living room sofa. Additionally, there is an option to install roller blinds (Raufstores) in the kitchen (the bay window or dining room window will definitely get Venetian blinds).
- We have worked a long time on the layout of the sanitary fixtures in the upstairs bathroom and were never 100% happy. What is your opinion on the current state? Any improvement suggestions?
- There are nicer things than the niche under the sloped ceiling in Child 1 - definitely. But it’s there, and we wonder how to use it more sensibly: in a children’s room (e.g., as a sleeping place, cozy corner, later maybe a desk) or in a dressing room?
- We originally did not want floor-to-ceiling windows facing the street, but we fear dark rooms even more... The alternative would be windows with a low parapet – but these have only about 2.5 sqm (27 sqft) of glass area instead of 3.3 sqm (36 sqft)...
By now, we are so blind from working on this that I can hardly judge whether this outdoor view is harmonious or not...
Many thanks for your interest and all feedback!
