Floor plan design for a new single-family house - 610 sqm plot - opinions welcome

What would one roughly pay for something like that if one simply asks to make a draft

You can't say that in general terms, according to HOAI these are the first three service phases. Thus, already 24% of the fee based on the billable costs could become due. It is different with an order based on hourly effort. I usually recommend that. If you go to a suitable representative of this craft with a good example, smart and organized ideas, it can also become significantly cheaper. It always involves an effort and thus costs. You are welcome to use our floor plan as a basis, if it is helpful.

Oh, are you really a Douglette? - I thought you earned your bread as a nerd?

I had to google that first. No, actually not, but I have a small child and we also buy a lot of groceries at a very well-known drugstore chain. That does add up.

What speaks against building the current house again in your specific case?

In our current house, many things are not like in the floor plan shown here. We built significantly smaller, and for example I hardly have space for a little Christmas tree on the ground floor, our pantry is way too small and because of this bricked-off corner, which was not visible in the construction plans, I can't even fit the 2 shelves that I wanted in there.
The wardrobe is un-bricked in the hallway and bothers me visually. The office has an L-shape (because of the pantry we squeezed in there), which I wouldn’t want again like that. And generally the very elongated, narrow shape of the kitchen/dining/living area. It doesn’t bother me directly, but I wouldn’t build it like that again.

I just don't know a solution that saves a ton of square meters,

The solution lies in leaving out something that is not urgently needed or can be accommodated elsewhere.

I have looked at many floor plans, already with the last house, and also now again, and with smaller square meter numbers I never find space for all that.

House construction is simply adjusted to the budget. As far as I remember, we still don’t know that here in the thread.
For you, this house would be a castle in the air.
In the meantime, I also opened the floor plans because you made me curious : they aren’t really very ingenious either. It’s a common floor plan (just a completely different concept than a Frisian or captain’s house from T&M, and I have a similar one;)). And even with this concept, the building envelope, floor area ratio, etc. often plays a role. It’s obvious here that the house was elongated, among other things by separating the technical room, utility room, and pantry until everything fits. At first glance, that looks great and impressive, but for example, it makes the hallway quite long and can also be impractical.
Investing in size always works well for a design, but most people cannot afford that. So why aim for oversize if it doesn’t fit your own life (budget + plot)? That’s why you set the budget at the beginning, then the room program, and then adapt the latter to the possible sqm. That’s also why storage rooms are integrated into the technical room and fairly intelligent yet often expensive solutions are forgone.
Your list of what this house has, another house has too—not all, but many (except for the separate pantry in ours as well ;)) Your hidden wardrobe, for example, I don’t see at all. Here, we have already discussed smarter solutions to about 80% of the walls, which were not even expensive. And I don’t recall if you posted your house floor plan here for discussion, but surely the topic of the wardrobe came up?!

On a faraway other platform, a house/floor plan was also requested (the day before yesterday): “How do you find it?” And it actually had everything noted somewhere over the last 10 years as must-have/want-to-have. Including a basement. So everything was huge (island, roof terrace, children’s bathroom, tunnel fireplace, etc.), but the paths to the basement are not very practical. The floor plan was very, very similar to this one (a bit shorter because all the ancillary rooms disappeared in the basement), only it was one of those Bauhaus design things. (this has nothing to do with this, but it really had everything you could count as "mainstream broth" (except for the air space). And I have to say: it was terribly boring to look at, without charm—I hope it gives you courage ;) )

At the current point in time, we are wondering if we have overlooked something or if there are still suggestions for improvement.

Feasibility of the ceiling construction in the living and dining area with the walls above on the upper floor (question to the structural engineers)

Both questions merge into one. I’m not a structural engineer, but on second glance the many offsets stand out, which do not make the statics any easier, and are certainly not helpful: for example, in the hallway there are two visible offsets funneling the hallway, which is over 7 meters long. On the left, at the corner of the wardrobe cabinet to the staircase corner, the straight line is missing to realize a ceiling beam well there, then following the staircase, which ultimately narrows the hallway to 150 cm.
In a simple gable house, in my view a load-bearing wall parallel to the ridge is needed. You have also drawn that and it seems to be on the left side of the hallway. The vertical wall at the bay window of the living room also serves as a ceiling beam. But these two walls are not aligned, but offset, so they cannot serve as load-bearing beams.
The location of the chimney does the rest, so nothing can really be load-bearing here.
A solution could be to move the small exterior wall of the living room in line with the hallway wall. The same problem runs through the upper floor.
Then it is noticeable that you have not allocated a wall for the front door. If it’s there, the entrance area either becomes narrower or the door to the WC will no longer fit.
The technical room (TK) could be too small. You need about 1 x 1 meter for the domestic hot water storage tank. That would only fit at the back. There is not much room sideways either because the plumber also needs access. If anyone has a smaller construction, especially with the new technology, name it for later discussions :)
Just found:

Technical room for heating system, heat pump with hot water storage, photovoltaic system with battery storage, and ventilation system with heat recovery

That won’t work in that room.

If you plan that large, I would also schedule a concealed wardrobe in the entrance area. The 150 cm wide cabinet only accommodates a fraction of four people. Thus ( ) coat hooks and shoe cabinets will decorate the walls, which then rob the hallway of any spaciousness.
Separating utility room, pantry, and technical room may be very sensible. Whether a laundry chute in the master bathroom is well placed can be debated—after all, from a certain age on, you don’t tidy up after the kids anymore. And then the shaft in the master bath doesn’t bring joy if the kids have to go through the bedroom to get rid of their laundry. I would rather think of a utility room upstairs if building on a large area.
I personally always criticize that the chill room is used as a passage room. So here too.

The upper floor looks a bit like Tetris: walls have been moved so that corners and edges appear everywhere.
Certainly, it could also look like this somewhat with fewer corners. Then theoretically, the stairwell could still be separated as a parent zone if the piano is too loud in the long run, without causing another offset.

The bathroom with 9 sqm could theoretically be enough, but you can see with a washbasin of 50 cm depth and a tub of 180 cm that the movement radius is very limited. The shower with 90 x 90 (without frills like partition or tiles) is almost a joke in a house size over 200 sqm. I gave the toilet the necessary space. I think you gain more with a conservative layout. With 2 people, a modesty screen isn’t necessary; you can talk to each other :)

(Tub: 80 x 180, shower 90 x 90)

But since changes due to the technical room and a central load-bearing wall cause many alterations, the cards will partly be reshuffled anyway.

Regarding the children’s rooms, which are work, sleep, and living space for children all in one and thus should receive the brightest spot in the house, I think already mentioned that?! Otherwise, you can find this out on Google as well. Bedrooms in the south or southwest are generally rather pointless, if not counterproductive.
I don’t think you need over 50 cm on the outside walls!

Do you even need "more" input than you could get from @kbt09 or @Würfel*? ... I could tell you the way to @kaho674 ...

Why do you always forget me in the lists? This is already the third time... :(

In the meantime, I also opened the floor plans because you made me curious, : they’re not really very imaginative. That’s a common floor plan (just a completely different concept than the Friesen- or Captain’s house by T&M, and I have a similar one ;) ).

We had the G164 from T&M redesigned a bit.
The office on the ground floor had to be included and a few other little things. The wardrobe is right in the middle of the hallway, not very clever. For us, it ended up under the stairs. The plan at first was: We only ever hang our three jackets that we’re currently using there. How well has that worked? Well... o_O

And with this concept, the building envelope, floor space ratio etc. often play a role. Here it’s obvious that the house was elongated, among other things by separating the utility room, laundry room, and pantry until everything fit. That looks great and impressive at first glance, but for example it makes the hallway quite long and can also be impractical.

Yes, the hallway is long, tubular, and takes up almost 16m² on the ground floor (in my drawing of it), which you can hardly use.

Your list of what this house has is also something another house has—not all, but many of these (except for the separate pantry, also ours ;)) I don’t see your hidden wardrobe at all, for example. We’ve already discussed roughly 80% smarter solutions here, which weren’t even expensive. And I don’t remember if you posted your house floor plan here for discussion, but surely the topic of wardrobe came up?!

Unfortunately, I didn’t back then. At that time I wasn’t yet in the forum, or at least not very active in writing. I never posted the floor plan here; you’d probably have torn it apart in mid-air.^^ But now it is what it is.

On a faraway other platform, a house/floor plan was asked about (the day before yesterday): “What do you think of this?” And it actually had everything that had been noted somewhere in the last 10 years as a must-have/want-to-have. Including a basement. So although everything was huge (island, roof terrace, kids’ bathroom, tunnel fireplace, etc.), the ways to the basement weren’t really practical either. The floor plan was very, very similar to this one (a bit shorter because all the ancillary rooms disappeared into the basement); it was one of those Bauhaus design things. (this has nothing to do with this, but it truly had everything you could list as “mainstream stuff” (except the void). And I have to say: it was terribly boring to look at, without charm—I hope that encourages you ;) )

I have absolutely nothing for these Bauhaus blocks. I have a construction company in the south that I find very sympathetic so far, but all the houses they sent me as flyers look somehow modern and blocky. Those black windows that wrap around corners, etc., I don’t like any of it at all (no offense to the people who build like that here—I know my taste is very old-fashioned). I also don’t care about voids. But I do care about the pantry. I even love my small, enclosed, totally not-the-way-I-wanted-it one. :D

If you’re planning such a large house, I would also plan a concealed wardrobe in the entrance area. The 150 cm wide closet only takes a fraction of four people’s clothes. So ( ) coat hooks and shoe cabinets will also decorate the walls here, which will take away any spaciousness from the hallway.
Separating utility room, pantry, and freezer room might be very sensible. Whether a laundry chute in the master bathroom is well placed can be debated—after all, at a certain age you no longer tidy up after the kids. And then the chute in the master bathroom won’t make anyone happy if the kids have to pass through the bedroom to drop off their laundry. I would rather consider a laundry room upstairs if you build a large area.

I am generally not a fan of laundry chutes. For the new house, I would much more consider whether I want a laundry room somewhere upstairs. So if you already separate freezer room and utility room, it would make sense to have the utility room upstairs. I actually always carry laundry downstairs to wash it, and then carry it back up again after washing.

I think you gain more with conservative furnishing. With two people, a privacy screen is unnecessary; you can just talk to each other :)

Or do it like us: don’t have any shame anymore. :p My husband saw me give birth, so since then I can save myself all that shame nonsense. :)

The rest over PM, ...

Yes, the hallway is long, narrow, and consumes almost 16 m² on the ground floor (in my drawing of it), which can hardly be used.

Mine is roughly 14 without the stairs.. but it doesn’t have to be square meters to be exclusionary. But it’s not a telescope either, and the length is what matters.

Or you do it like we do: stop being ashamed.

That’s what I mean too ;)

@ , respect! Thank you very much for this thorough and deep engagement with the draft! Especially great are your suggestions for improvement. You have nicely identified the problematic areas, now I just have to see if I can fix them...

on a faraway other platform the day before yesterday also a house/floor plan was asked about: “what do you think about this?”

Can you send me the link once, gladly also via PM if this is not so appropriate here...

coat hooks and shoe cabinets will also decorate the walls here, which will then take away any spaciousness from the corridor.

Oh yes, I would have liked to integrate the coat rack better too. Ideally, from my point of view, there would have been an internal connection between the garage and the house hallway. At the same time, this would have created enough storage space. Unfortunately, this did not work out due to space reasons. The current draft at least offers the possibility to use the space under the second flight of stairs. Here I see enough space for a large shoe collection and maybe a few jackets that currently don't fit the season.

chill room as a walkthrough room. So, here too.

Do you mean the upper study that is openly integrated into the hallway? That could be easily (even later) separated.

ü50cm on exterior walls

Probably too much. I am waiting for the building energy law calculation and then prefer to be happy about every centimeter rather than having the draft ruined later because of it.
