Floor plan optimization city villa + fill consideration

I would also take the T solution and give up 20 cm from the living area. Then I would have 3.07 length for the T wall. Still certainly too tight?

I am currently planning the windows.
I noticed that the floor-to-ceiling windows/terrace doors are 2.13m high. (See #1) Is that normal? It seems a bit low to me.

The house will be located in a new development area where you stand very close to the neighbors. We don't want it to be too visible. Are these narrow, elongated windows at a higher sill height also suitable as the sole main windows? For example, in the bedroom 2m x 0.76m at a sill height of 1.50m?
I think the window shape is called light bands.

Do you have any tips for windows?
I feel a bit left alone. The architect assigned to us is no good. So we're on our own regarding the floor plan and window planning and aren't making progress.

I would generally make the windows as high as possible. I once visited a show house where I noticed that there was at least 45-50cm of space above each window up to the ceiling. Even though the ceilings were nicely high, it just didn't look good with the windows. Our floor-to-ceiling windows are 2.35m high, so there is still 35cm space to the ceiling, which looks good.
We also have a window like that above the bedroom bed (like in your photo), which also looks nice... but that window would never be enough on its own; we also have a 1.76m wide floor-to-ceiling window in the bedroom. Our bathroom window is also 1.76m wide and about 1.40m high. Everyone has neighbors, but there are many different possibilities for privacy screens, such as double roller blinds, pleated blinds, or curtains. That way, plenty of light still comes into the rooms and no one can look in. I wouldn't use a narrow light band at 1.20m height in the kitchen unless you enjoy working in the dark in the kitchen.

Thank you for your opinion. Which window would you recommend for the kitchen? The kitchen is open and I thought light would also come in from the south side through the dining area, or is that not enough for the kitchen?

This is what it looks like for us, the window in the kitchen is 2.25m wide and 1.44m high. Behind the dining table there is a large bay window about 4m wide, it is not too bright

It is not enough at the kitchen worktop if the window is several meters away, light must be directly at the worktop.

It looks great at your place! I need to be braver too. All the neighbors are just a few meters away, and you don’t want to be sitting in a glass house.
Our house planner designed small windows with us. And the architect didn’t say anything about that either. I really feel left alone.
May I ask how you arranged the couch and how many square meters your kitchen is?
Did you plan your windows alone or who advised you?

Our ceiling is 2.55m high. Currently, in the apartment, all floor-to-ceiling windows are 2.20m. I think that would fit if we did the same in the house.

Our kitchen is 13 sqm. We have the couch as a corner sofa in front of the living room window and against the left wall (if I describe it based on your plan). We planned the windows ourselves, as well as the whole house. You should just take a look at 2.55m room height in a large room in a show house and then decide if you like it. If the development plan allows it, I would always plan as high as possible. Best regards Sabine
