Cozy living room, not too big is liked

At first we wanted the laundry room next to the kitchen, but it also fits as is now.

Preferred heating technology: so far planned is air-to-water heat pump, still gathering information

If you have to do without, which details/extensions
-could you do without: it is already quite compact
-could you not do without:

Why is the design the way it is now? For example
First own attempt, please be kind
Not everything fits 100% yet, first rough floor plan.
Windows, bathroom and kitchen are not yet finally furnished/aligned in terms of furniture.
Stair size estimated for now, but leaning strongly towards a landing staircase.

What is the most important/basic question about the layout in 130 characters?
Are there better solutions due to orientation?
Generally things that might not work that I have overlooked?

Take a look at the distances you sometimes have. Washbasin bathtub, bathtub toilet The bathroom may only be entered with a maximum shoe size of 40. Living room. Today someone kindly posted a picture of [3,5m room depth]. There 2.75 is more than little. I find the hallway almost too big in relation to the rest.

For the size, I would consider building "American style," meaning without a real hallway. Front door directly into the living room and then using tall shelves as room dividers. Or even playing with the staircase.

On the one hand, the common area is very, very narrow (you'll strain your eyes there, my mother would say), on the other hand, the guest room in L-shape is too small or the legs are too narrow to furnish it well. It is not suitable as a bedroom for someone with a disability. The adjoining WC is not suitable either. You should forget that idea with the minimal size. A rectangular room would be better here, while a utility room in L-shape would not be a problem. The staircase is oversized for the house! Where would your 2-meter line be on the upper floor? The bathroom won't work the way you imagine it. There must be about one meter of free movement in front of the toilet, the shower has its dimensions, the bathtub has its dimensions. I would also go for something more American, or alternatively Japanese: a home office in a closet room, for example... but you would have to weigh whether a few more square meters in the floor area would be more advantageous than such built-ins.

I also fear that some things here are too small/too tight. Crawling into bed from the foot end does not seem very comfortable to me, especially if you also have to be careful not to bump your head. Is there a [Kniestock]?

Just checked if there are even such "small" floor plans on the net. Came across the Raumwunder 90 from Town&Country. Maybe it can be used as a basis?
