ᐅ Single-family house with a pitched roof, without a basement – feedback welcome

Hello everyone,
We are planning to start building our single-family home next year. Currently, we are working on the floor plan, have tried several versions, and are quite satisfied with what we have so far.
I would appreciate it if you could share your opinions and feedback on the floor plan.

Development plan / restrictions:

Plot size: 445 sqm (4789 sq ft)
Slope: no
Site coverage ratio: 0.35
Floor area ratio: 0.7
Number of parking spaces: 2
Number of floors: 2 full stories plus attic conversion later
Roof style: gable roof
Maximum height: eaves height 6.5 m (21 ft 4 in) on the street side
Heating: geothermal
Personal budget limit: 400,000

Client requirements:

No basement
Number of occupants: 2 adults and 3 children
Open kitchen with sliding door
Double garage

The attic will initially be used instead of a basement.
It will also house the heating system and utility room with washing machine and dryer.
Since our family plan is not yet final, an additional children's room could be added in the attic in the future.

Has it been confirmed that the double garage, half of which is located inside the house and connected to the other external half, is permitted as a boundary garage?

Yes. We have the approval for that.

And also, is it really allowed for the garage to be this close to the street? I would have expected at least 5m (16 feet).

And we also have a building permit / planning permission for that.

We would like to hear some opinions on the floor plan.
