Floor plan opinions single-family house 140 sqm 2 full floors

You are basically right, he should know that. In practice, however, with this attitude you are making a fundamental mistake, because as the client you are responsible for how the house turns out. This is not about control, but about risk management and the four-eyes principle to avoid mistakes. Have you never made a mistake even though you should have known better? If you accept a room that is too small without checking yourself whether it can actually work or having it plausibly explained to you, that is your responsibility. And then you get what you order and pay for. The complaints afterward when things turn out differently than the client expected are huge, and the solutions to such conflicts are never satisfactory. The fatal sentence that always comes up then is "I assumed that...". Better to ask one time too many than one time too few and think for yourself – just as you do with the size of the study. Here you can estimate how much you need and make a confident decision. Do the same for the technical room, which you cannot assess properly without dealing with the subject.

With the above-mentioned fundamental mistake, small business owners go bankrupt, who then say: I didn’t know that, my accountant does the bookkeeping, he should have known that. It doesn’t matter what he should have known – the entrepreneur is responsible and bears the consequences.

About the technical room: just google it once

A draftsman draws placeholders, an architect possibly deletes them and places them more sensibly with knowledge of the technology. During the shell construction phase, the craftsmen/construction managers look where it makes most sense to put heating, controlled residential ventilation, connections, and electrical cabinet. So much can still change. Craftsmen think differently though, and more practically for themselves. Pipes and lines run along the walls, and between them and the devices there must still be room for tools to install and maintain/repair the pipes. I have nowhere seen a heating unit mounted on an interior wall. The sink is misplaced there and is not needed if the dryer is upstairs. The area between the doors is hardly useful – except as a hallway replacement. It is cheaper to have space behind the doors for cabinets. Regarding my advice: sofas are usually deeper than a door is wide. Wrong dimensions show a false representation of proportions.

Where is north, actually?

Thanks! Okay, I understand from the comments. Door outward because it takes up too much space, and the technical room should be well planned to ensure everything basically fits. During the construction itself, craftsmen and installers will look again where makes the most sense, but it is important that at least everything is planned in once and it works out.

In itself, a technical room with just under 9 sqm should be sufficient for a 140 sqm house.

If the shower in the guest WC is removed, then it will become a bit bigger. I have to think about that.

Still remains the bathroom upstairs, which is not planned with a good structure. I have to tackle that again.

And so as not to draw anger onto myself again, there are certainly better and more structured floor plans in general with different staircases, etc. However, this is a floor plan that we like in the overall context. If it were only 50% habitable now, okay then I would consider a completely new floor plan, but as I understand it, it is habitable.

Children’s rooms as well as bedroom and office have not been mentioned so far and seem to fit in size and layout, or were they not addressed due to too many previous errors with kitchen, technical room, bathroom, and wardrobe?

North is at the corner of the house in the guest WC. It runs diagonally through the house from the guest WC corner (north) to the dining room corner (south).

Oh, so an asymmetrically divided double-wing door with a mullion, and next to it a fixed element?

Yes, I think that's it. But maybe just simply install a window front with a lift-and-slide door there. I somehow got confused with this door with mullion. But practically, the other variant might be better.

Hallway, cloakroom: so, it is normal for the rubber boots, work shoes, garden clogs and street shoes as well as sneakers to be downstairs where they are needed. That you should sometimes switch shoes over the days is also normal. Whether you take the street shoes upstairs – I don't know anyone who lives like that.
So having .only. one pair of "shoes" in use is not normal. Yes.

I simply oriented myself to my current living situation and also grew up in apartments and not in a single-family house.
In the past and currently, I live in 75 sqm with 2 adults, 1 baby and 1 dog. The hallway is 4 sqm and serves as a connection to the bedroom, bathroom, apartment door and living room door.
There is a coat rack on the wall as well as a shoe rack and a sideboard underneath. You can comfortably walk to all rooms.
Winter coats are stored in the closet after winter and vice versa in summer. The same goes for winter shoes and summer shoes.

Yes, currently I would like more space since now the little one's shoes are added.

Therefore, the cloakroom in the house is already about twice as large just in terms of floor space. In addition, there is certainly space under the stairs for a chest of drawers or built-in closet (since the stairs have closed steps).

I understand the point and I would like to build everything bigger. But I come from a much smaller apartment and have survived so far. More work and you have to strictly tidy or put things away, but it has worked.

What is the alternative? I save the money for the single-family house and move into a 110-120 sqm apartment, where the cloakroom is certainly not larger either.

What I want to say with that: I would gladly have 200 sqm with a dressing room, but I will not be able to afford it at my place of residence. But I want to offer my family the luxury of a single-family house with a garden in a nice settlement on the edge of the forest. The house should be comfortable to live in but also appeal to us from outside and inside. I think if I only take the best floor plan there is, I won’t be happy either, because I would have wished for a straight staircase style-wise.

I am very grateful for the answers and opinions and just want to simply explain my thoughts on why it turned out this way.

What are the dimensions of the stairs? They look quite steep, but I can't read the measurements right now. I really like the idea of the asymmetrical window, I've already seen it and it can look cool. And it might also be cheaper than a lift-and-slide door. The latter are really expensive, unfortunately I speak from experience by now.

and I just want to simply present my thoughts on why it turned out this way.

That is also completely fine. And the frequent writers and advisors also adjust to the fact that a TE doesn’t know any better or doesn’t suspect that living in a house is different because of the garden, gardening, and needs or wishes that grow with a house.

I oriented myself to my current living situation and I also grew up in apartments and not in a single-family house.

That is exactly why, for example, this forum exists—to make future builders aware of one or another aspect. What you make of it is then your decision.
However, I am quite surprised why there was absolutely no reaction regarding criticism or improvement suggestions. Has the building application already been submitted?

I would gladly have 200 sqm

I would not.

I understand the point and I would like to build everything bigger.

The crux or knot in your thoughts is actually that no one is blaming you for the size, nor is there any criticism of the size, but even suggestions are made (Kerstin in #15) that much doesn’t work as it should functionally because of, for example, the stair location, but it’s not because of the size, rather one or two initial mistakes, so that a domino effect occurs here.
I remind you:

We want a functioning house that works for 2 adults and potentially 2 children (1 present).

and have survived so far

I guess we don’t need to exaggerate on equal footing when it comes to several hundred thousand euros that you have to pay off over 30 years.

But I don’t find it too small for cooking together. You have enough space for chopping.

Where? Ok, you now have some free space next to the sink because you omitted the door for a tall cabinet. (Does your wife already know about her luck in no longer getting this feature?)
The problem here is actually that some things in a kitchen are kept within reach (knife block, common spices, opened seltzer bottles, the new kitchen appliance, and the coffee machine). The counter is less suitable, rather exactly this corner. Then somewhere lies exactly what should be chopped, then your cutting board, then the container where it should go, then other ingredients like liquids, seasoning, herbs. That can’t stand optimally anywhere, even if only for a short time. Then perhaps the cookbook or tablet with the recipe...
The space between stove and sink, the corner—hardly a grown person fits there. And if they do stand there, they block sink and stove at the same time but can’t chop well.
And where are bowls, glasses, cups, and plates fetched from?

Storage options are planned for the pantry.

One is reluctant to go to the pantry for that every time. A kitchen should not be fragmented like this. A kitchen should function with its storage options for cooking and dining utensils as such. Without a pantry. And when you have children, there must already be enough storage options here for several lunch boxes and containers of all kinds and sizes, measuring cups, etc. Your family is growing right now, and the household must grow with it.
I do not want to convert you or persuade you to do something differently. Only some clarification is needed here about how much must be within reach in a kitchen. And if everything first has to be moved forward from the back, then you need counter space to temporarily set this stuff on.

@Milka0105 What are the dimensions of the stairs? They look quite steep, but I can’t read the measurements right now.

They should be roughly about 3.70.

The staircase itself could also be continued into an attic. ... I don’t remember if this question came up in this thread.

I think that was in another one from yesterday.

Yes, I think that’s it. But maybe just simply install a window front with a lift-and-slide door there. Somehow I got mixed up with that door with a mullion. But the other variant might be more practical.

I think the asymmetrical window idea is great, I’ve already seen it and it can look cool. And it might also be cheaper than a lift-and-slide door. The latter are really expensive; unfortunately, I now speak from experience.

Lift-and-slide doors are yesterday’s news, no one wants that nonsense anymore tomorrow. A passing trend that overslept its death—nothing more. Unnecessarily expensive (and heavy) too, yes.

In the past and currently, I live in 75 sqm with 2 adults, 1 baby, and 1 dog. The hallway is 4 sqm and serves as a connection to the bedroom, bathroom, apartment door, and living room door.

I don’t understand why people don’t simply "trace" their current apartment and mark the pain points and wishes there.

I am really grateful for the answers and opinions

and why then do you lack the willingness to revert to the preliminary design phase?
