Unfortunately, it will also be very tight in terms of width in the living area and quite a small kitchen area. 10.12 house width ... should be about 9.3 m interior width.
Kitchen with island approx. 280 cm
Table, so that you can still walk through properly approx. 350 cm
Remaining to the right approx. 300 cm from the back edge of the sofa to the right outer wall.
I still don’t quite see how the staircase should run.
Door garage/utility room... I would do without it, but if it is there, you have to consider what it is used for. Unloading the trunk... directly into the house. Since the garage is not very wide either (bicycles etc. also have to be somewhere), the door should be planned further. It also has the advantage that the upper wall of the utility room can be used properly.
---------------------
As a starting point, I would find the Maxime 300 mirrored usable, the utility/technical room would just be without garage connection.
