Floor plan for single-family house 164 sqm / 2 full floors optimization

It was just an idea. I have no real idea how far a landing staircase would extend into the living area. If the utility room upstairs were removed and the bedroom and bathroom combined, maybe the door could still be shifted. The half-turned staircase is okay for us. A landing staircase would simply be easier to walk on. For cost and aesthetic reasons, we do not want a bay window on the outside.

It is a corner plot, and a street runs along the west and north sides. Therefore, we have arranged the house so that it opens to the interior of the property to the south and east. The west and north sides should be more "visually protected." A double garage is also to be placed on the east side.
A corner terrace is planned along the floor-to-ceiling windows on the east and south sides. That way, you would still have sun and light from the west in the evenings there.

What is the story height? Then one can calculate what is possible.

In my opinion 17*18.16 approx. 3.09m Unfortunately, it is not easy to read. I would replace the dressing room with a children's bathroom and then place the dressing room between the bathroom and bedroom. Access to the bathroom through the dressing room, so the pedestal staircase also works.
