Hello everyone,
I would like to share my floor plan here to get some feedback for optimization. We are already quite far along in the planning process and are generally satisfied. However, we can still make minor changes without any problems.
A brief introduction about us: a family with two children (2 and 4 years old). I work full-time without working from home, and my wife is currently not working but plans to return to part-time home office work in 1-2 years.
Mainly, my focus is on the window planning and the layout of the bedroom and bathroom. Regarding the windows, we wonder if there might be too many and whether that has significantly increased the costs.
Children’s rooms:
Do we still need windows facing east/west? This is probably a subjective question, but I’m happy to hear your opinions.
Bedroom:
Are windows facing north or west unnecessary? Alternatively, we could consider moving the partition wall so that the dressing room’s window also provides light to the bedroom.
Bathroom:
I’m wondering if the layout can still be improved, for example, by using a T-shaped design. We also have the issue of an extra window next to the toilet, primarily for ventilation. The window above the bathtub is not ideal for ventilation as it is hard to reach.
Any general comments are also welcome if something looks generally unfavorable.

Given the room dimensions, I can’t place the dining table anywhere else but by the window. Since we can also mount a simple wooden board ourselves onto the window sill, we would save nearly €1000.
If I change the windows, the table will no longer be centered in relation to the windows and looks somehow odd.
The dimensions shown in the illustrations are from the floor plan. There may be a 1-2 cm (about 1 inch) deviation here and there, but only in places where it is not relevant.

Since we can mount a simple wooden board ourselves on the window sill, we would save roughly 1000 € (about 1100 USD). Depending on which window sills you have, you could have one made from the same material (wood) in the desired size as a window bench; that’s how we did it. The windows are mounted on the outside, so part of this bench lies inside the reveal and also has sufficient support. You can use it for nice decoration, plants, or similar, but nobody will actually sit there, even if you think so. You’ve planned for six dining seats (hopefully accurately measured); the seventh or even eighth person will sit on a stool or folding chair if that ever happens. What happens often, happens often, and what happens rarely, happens rarely. The days of keeping extra space for large family gatherings on standby are over; guests will always find a place when, exceptionally, there are more of them.
The picture you posted in #32 is misleading and not a good reference for you. As I already mentioned based on the plan page, the bench would then protrude more than 30cm (12 inches) into the room. What is not clear in the nice photo is that this 30cm (12 inches) deep overhang would also apply to the two side parts or all around. Try holding a 30cm (12 inches) deep board against the wall and imagine that…

If I change the windows, the table won’t be symmetrical to them anymore and it feels kind of odd. Try positioning the table crosswise INTO the room with correct dimensions and directly opposite the entrance. In my opinion, that’s where it belongs. Then look at the windows. I can only imagine it when I see it, but a wide window (standard height or slightly lower) behind it would fit well, and in the kitchen area just a normal patio door to the outside. Perhaps a standard patio door in the living room would be enough as well (or fixed glass), if the central window is designed prominently. That would also look consistent from the outside.
Maybe you already fixed the interior dimensions of the house too early and that’s why you’re going in circles?
I’m also bothered by that 1m (3 feet) deep short wall segment the door is supposed to hit. With such tight dimensions, 1m (3 feet) is actually quite a lot.
Making later adjustments to floor plans is difficult because even small changes have consequences. That’s why it makes sense to go back to square one and start fresh from time to time, but that doesn’t seem to be your plan.

Try placing the table crosswise IN the room with the correct measurements, facing the entrance. It would look like this. The one meter (3 feet) wall annoyed us later as well. The structural calculations were based on it, and since this wall is load-bearing, changing it would lead to additional costs (we don’t know the height).
But the advantage of having the dining table further in the kitchen area is that the wall visually separates the spaces.

Install the windows flush to the exterior, so part of the sill lies within the reveal and has enough support. We had thought about that too, but then it would have to be done on all windows; otherwise, it would look strange.

You have marked 6 seats at the dining table (hopefully to scale). The table is quite generous at 2 x 0.9 m (6.5 x 3 feet). Currently, we have 1.8 x 0.8 m (6 x 2.5 feet) with an extension that increases it to 2.8 x 0.8 m (9 x 2.5 feet).

Making changes to floor plans afterward is difficult because every small adjustment has consequences. That’s why it makes sense to occasionally start from scratch, but that doesn’t seem to be your plan. I basically agree. However, this process has already taken so much time that I don’t want to start over now. In the end, having the perfect floor plan isn’t the most important thing in life. Our rental apartment in Berlin was very awkwardly laid out, yet we still felt very comfortable living there.

Maybe not after all. I meant that in both the kitchen and living room there would each be a 1m-wide (3 feet 3 inches) door—unlike the currently wide elements—and the table (180cm (71 inches) long is already generous) would be positioned exactly opposite the entrance. In case you want to show that again?
We approved a serious mistake: a thick post too close to the walking path that had been drawn smaller than it actually was supposed to be. Luckily, we raised concerns, and it was changed; the beam was made significantly thicker, which we had to pay for, but maybe such a correction wouldn’t be a real problem after all, especially since you plan to live there for a long time.

Our rental apartment in Berlin was extremely poorly laid out, yet we felt very comfortable there. I understand that, but with that last argument, you could also live in a tent, which I’ve always found nice too.
Building a house should feel like reaching the maximum, because knowingly building in weaknesses and paying for them a lifetime wouldn’t appeal to me.

Would you like to show that again? I did. But the wall really gets in the way. I temporarily removed it as a test and replaced the cabinet with something smaller. I feel there are a bit too few windows facing the garden, but otherwise it already feels more spacious. However, I do miss the structure that the small wall and the dining table in the kitchen provided.
If the table moves that far out of the kitchen, the kitchen layout could of course be planned differently. But that tends to create a domino effect.

I could live with the floor plan as it is, but since we had to wait about three quarters of a year for the approval of our funding, you naturally start to think about what else could be improved—and you probably always find something.
