I see here exclusively rooms of significantly lower residential value or utility than their nominal floor areas would suggest.
That would be my main argument against the GU box-layout, even if otherwise a standard 08/15 might suffice: the many residential-value dead square meters that such a unloving design brings along.
The total area would, for example, quite certainly allow for a proper dressing room instead of this wardrobe privacy screen. One might not like controlled residential ventilation, but not at the same time with a small bedroom air volume. A toilet in the basement means a lifting station.
I do not understand the objection of the building inspector with a garage in the east: that would only be 3m, and I would, in any case, not go below 5m in front of the gate. I find the suggestion of the eastern driveway good.
