Floor plan of a single-family house with 3 children's rooms and a double garage

Not the stairs, but the shed roof is the wrong story here.

I'm talking about the gable roof house anyway!

However, the staircase would then be close to the ridge and therefore not nonsensical. A gable roof would probably be appropriate for a city villa, while the floor plans here fit the genre of the "Anstattvilla" almost stereotypically ;-)

My boy:
I move the house entrance and the staircase. What remains of the floor plan is practically nothing. Maybe the office at the bottom right of the plan.

And there you go again with your Anstattvilla... You spin pirouettes with your replies without being constructive.

I am relocating the front door and the stairs. What's left of the floor plan is practically nothing. Maybe the office at the bottom right of the plan.

This also roughly corresponds to my expectation of the low correspondence of a better design with the one submitted.

Here you come again with your instead-villa... You spin pirouettes with your answers without being constructive.

This claim is boldly false: in post #16 I last gave a detailed diagnosis including very easy-to-implement therapy recommendations, as well as (with an even simpler, concise single measure in post #24).
#1 importing a floor plan template must inevitably fail if this template has a different "family status";
#2 draftsmen are trained to distill working plans from positively tested functional designs,
but not to develop their own designs or modifications;
#3 the indentation of the ground floor has the annoying effect of unnecessarily compressing the living space, and at the same time
#4 as a shading measure against the morning sun, it is an utterly exaggerated measure.

And what is true must remain true: the current design uses floor plans of the category "instead-villa of the most standard kind," while a gable roof would be fitting for a city villa without quotation marks, for a "city villa" aka instead-villa, it is almost a cheeky variation.

So, I summarize the measures:
#A only with a room program and wish list, but explicitly without a template
#B go to an independent architect instead of a general contractor inclusive planner
#C don’t be surprised if they develop the more difficult floor first

All of these are simple measures - but by no means a reason for the claim that I gave no advice, but only confined myself to mocking the quotation mark city villa :-(

If the OP is really willing to shell out 600K for the house, I am somewhat surprised by the rather modest design. I’m not exactly sure if we are still at 3k/sqm at the moment, but for the budget, I would expect around 200sqm. I don’t see that.

I’ll just bring an example with an attic conversion with a 1m knee wall and a total height of around 10.60m. Roughly just over 200sqm.

From the utility room to the garden, I would still plan a patio door. I quickly forgot that.
Whether the support next to the kitchen island is absolutely necessary, I unfortunately can’t estimate. Without it would of course be nicer.

The children’s rooms are about 18 to 19 sqm each. If that is too much for the good folks, one can also design smaller children’s rooms and plan the guests in the upper floor instead:

At least this way the OP can consider whether that would be too much house for him. :)

You’re basically looking at a two-story house plus attic conversion - ok. It would also be interesting, considering that with a 470 sqm plot you’d still want some garden. I would have chosen a slightly steeper roof and seen the living space around 160 or so. That way you get adequate room layouts on 3 levels. In the attic conversion then just bedroom and storage, on the upper floor guest room and three children’s rooms.
