Floor plan single-family house 110m² - ground floor + upper floor - first draft room layout

I never said that I WANT to fit everything in and insisted that it somehow has to work. Ok, we will cancel the pantry. Ok, we will cancel the second bathroom and make the children's rooms a bit bigger instead.

All good. If your building partner/architect didn't tell you that, then we have now told you. Ultimately, it has reached you. You can try, but overall the design has to work. Maybe you can fall back on a gas or ethanol fireplace?!

Constructive criticism is always welcome, but with statements like "a 110m² house is not a lifelong project but a temporary solution," I can unfortunately do little.

yes, but why are there no answers to questions like how the basement is, where the driveway is, how the strip of land in the east is designed, and whether windows can and will be placed on the east side? Without this information, you can't make a proposal - or do you see it differently, ?

Open living certainly means more spaciousness, but beyond a certain size, one easily slips into something known from one-room apartments. Lack of storage space, lack of places to put things. Zoning is then extremely important. Even if you say that as storage space we have a cellar and an attic, with children in the household you often want many things to be accessible in the living area but not always visible.

Can you explain in more detail how the legal requirements are regarding the room in the attic? That must be clearly defined. Would it possibly be allowed to set up a play area for the children there? I would take a really close look at that. The space has to be good for something. And from when is it allowed to be used as living space?

We live in a 100m2 townhouse. Everything works perfectly. But for us it's spread over 3 levels, our house has different external dimensions. We have a "large bathroom," which is still smaller than what most here have as a second bathroom, and on each floor a toilet with a washbasin.
In tighter conditions, simple layouts without corridors and focusing on what is really necessary help. You can't avoid compromises. But then you end up with a house where you don't have to clean yourself to death, have lower energy costs, and it still suits you even when the children have moved out.

It also helps to get housing inspiration from other countries in order to imagine how to design small spaces. In many big cities, small floor plans are normal; small houses, for example, are also widespread in GB or the Netherlands. The furniture and living spaces currently fashionable in Germany in minimalist beige, gray, and natural tones are often substantial in terms of space requirements. I would suggest searching on Pinterest with keywords like small bathrooms, small bedrooms, small kitchens to perhaps move away from the standard furnishings.

don't you have a house with similar dimensions or am I confusing something?

Yes, we have very similar dimensions. If you are interested, I will link you our floor plan, ?

Open living certainly means more airiness, but beyond a certain size, you easily slide into something familiar from one-room apartments. Lack of storage space, lack of places to put things.

That’s true. The more open you design it, the more discipline is required to limit yourself to a few belongings. Otherwise, it will be constant chaos.

Zoning is then extremely important. Even if you say that we have the basement and attic for storage, with children in the household you want many things to be within reach in the living area, but not always visible.

Very important! Children have different things than adults. They need extra space – and there is always something new, not only because of unrestrained gift-giving from others but also due to the rapidly changing demands caused by growing up and getting older. We hadn’t considered that in our terraced house and accordingly often had uncomfortable chaos in the house – as did some of the neighbors, by the way.

With tighter living conditions, simple floor plans without nooks and crannies and a focus on the truly necessary help.

Yes, here it is appropriate to engage with the Bauhaus style as a source of inspiration. Hardly any style has brought the essentials so much to the forefront; some key figures of the Bauhaus dealt with the rational-functional use of space – for example, the great and rarely mentioned architect Margarete Schütte-Lihotzky. One can say that the Bauhaus school laid a decisive foundation for what we today call "modern." (That it has become customary to call everything angular and with a flat roof "Bauhaus" is just as absurd as calling a station wagon "sporty" – pure marketing hype. – I just couldn’t resist...)
