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!

10% to 12.5% (depending on the state). You can also build the house with a 2.4 m (8 feet) ceiling height and only 10 electrical outlets in total... meaning, just because you meet the minimum requirements doesn’t mean you will actually like it (a bit of a polemic here).

That amount is certainly sufficient, with almost 25% even significantly more — which is why I asked about the view. If you have a 5 m (16 feet) garden and then the next townhouse in coal black right behind it, you obviously don’t need panoramic windows. But if there is a field or forest, it is really nice to be able to glance out while having breakfast or sitting on the sofa.

By the way: you can also have a large window area and still keep usable floor space. I wouldn’t necessarily sacrifice one for the other: keyword floor-to-ceiling windows in every room that end up being blocked by a dresser anyway.

The exterior is being finished with brick cladding because it doesn’t increase the cost, and because we live in close proximity to a surface coal mine here in North Rhine-Westphalia. You can’t imagine the coal dust in the air and how much it damages the rendered houses in the neighborhood.
Oh – I don’t live or work that far away; it’s not that bad anymore. In earlier years, yes, but nowadays—with all the regulations in place—it’s quite manageable.

@Bauexperte: Why swap the bathroom and bedroom 1?
Then the little one would be running around right above me, he would have the darker side of the house, and the bathroom would be huge...

I’ve sketched out the staircase with a landing. Given these house dimensions and without completely redesigning everything, I don’t think it actually improves much. (Maybe I’m just afraid that the architect and my wife will tear me apart if I scrap the current plan :P )

Our main issue with the current design is the staircase, or rather the space underneath it.
Question: open (for light) or closed (with risers / partition wall facing the hallway)?
How is access to the storage space under a closed staircase usually done? Do you leave the back of the stairs open, or is a door installed?

Windows in the living room:
From the outside, it looked better to plan a 3m (10 feet) glass door instead of 2m (6.5 feet). But since the living room is quite small, the couch would definitely be in front of the third panel, and we’re unsure if that would look odd or make you feel like you’re being watched automatically...?

Bathroom / upper floor:
What do you think about the layout, especially the shower facing the door? Can it be extended a bit toward the door without problems? At what depth might it be possible to skip a glass door altogether? Currently, the shower is 100x140cm (39x55 inches), but I think there’s still room to extend it?
And under the sloped ceiling: is a corner bathtub or a rectangular tub better there?

By immediately, I meant immediately!
Not somewhere in NRW, but within sight of the excavator. Between the excavation pit and us lies a field plus a wooded hill – behind that, the steel giants loom...

A double-glazed door is installed opposite the hallway corridor on the ground floor in front of the stairs, which visually eliminates the appearance of the corridor.

Are you referring to both potential staircase/floor plan options?
