Floor plan single-family house 150 sqm with double garage

I'll give my unqualified opinion on the windows:

I find the parapet heights of the windows generally a bit high.

1.25m on the upper floor minus floor construction is about 1.10m, maybe plus windowsill?

Probably because of the gable roof, ring beam, and roller shutter box in the upper floor, all windows are only 1.01m high? Have you ever seen that live in a prefab house center or similar? It is often done like that there.

The window in the pantry is also only there for aesthetic reasons from the outside. It would be much more practical on the east side, then the north wall of the pantry could be filled with shelves uninterrupted. You have to weigh that up.

Who is allowed to clean the window above the bathtub? It always looks great, but unfortunately a bit impractical to clean.

But at the end of the day, you always have to find the best compromise between appearance and practicality. Unfortunately, architects usually think more about the appearance.

Right, especially the windows on the upper floor and in the children's room/office and then this high parapet height.
Then the bedroom justification no longer fits either, because with the parapet height you lie in bed and look at the wall.

With such floor plans, the specified parapet height actually always means from top of finished floor - right? That would at least match the height alignment line of the windows on the ground floor.

Floor-to-ceiling parapet height = 0 and 226 cm height
Parapet height 125 at 101 cm height also corresponds to 226 cm height again.

For the execution plans, you then have to pay attention again at what heights the roller shutter box etc. are installed.

Then the bedroom reasoning no longer fits either, because with the parapet height you lie in bed and look at the wall.

I had never noticed before that such a toilet window parapet height runs like a common thread through the house in living areas as well.

In such floor plans, the specified parapet height actually always means from finished floor level upwards - right?

Actually yes; and even if I subtract another 18 cm for floor construction, besides an still unusually high parapet height there are also low lintels. Something is wrong there.

With such floor plans, the specified parapet height usually always means from the top of the finished floor – right? That would at least correspond to the height alignment line of the windows on the ground floor.

In our floor plan, the parapet height is the distance from the top of the raw floor, maybe ask again. For example, in the living room, we have a parapet height = 1m, which then means a distance from the top of the finished floor to the bottom edge of the window of about 83-84 cm. I also find that a nice dimension. In the bathroom/kitchen it can of course be higher.

... and how high is your window opening then? It's about what the drawing could represent. It could mean either, depending on the settings of the drawing program. And, from the top edge of the unfinished floor, there would already be a window/terrace door, which ends with the glass at about 200 cm height. Who would want that?
