I believe the house is 10.49m wide and 9.99m long.
That's how it is, and that's how the floor plan works without any restrictions.
In such central matters as dimensions, I would not change the standard floor plan either; otherwise, you might as well do a custom design right away. The advantage of a type house comes from the routine in details that have been built exactly like this many times, and you don't change "too many" of those.
So first, adopt the original house dimensions.
We want at least a 7m long garage for terrace/garden.
With "
maximum 7m" I would have understood the context that more garden would then remain (?)
I don't know what the attic brings for this house. Without a basement, I tend here to exhaust the allowable garage length for building permission (so about 9 m). Otherwise, the car will only park inside in winter after the bulky waste collection day. Ownership sedentism influences the tendency to accumulate.
The cloakroom comes between the front door and the utility room.
That is probably a misunderstanding. I suspect you mean by "cloakroom" what I call "the coat hook rail". In the local community’s usage, "cloakroom" is rather interpreted as an accumulated pile of clothes, which reaches a decoratively damaging volume overall and must be removed from sight.

Don't let yourself be driven crazy: in the original ten by ten and a half meters, the Villa XL 2.0 V3 type also works in your redesign and is by no means a failed adaptation of "Jette" into the Schantalle format.
It also works with the staircase, and the north-south axis direction results from this format adjustment to the original dimensions.
This provider has also already caught my favorable attention due to its consistently suitable model range (many providers copy the wildest mixtures together and fervently hope that the customer wants something different). Another provider I like from your area is GSE; but from Massivhaus Mittelrhein, I already like the proposals with significantly fewer changes. However, I personally favor "Domus" instead of "Villa" as the base series.
