At first glance, I find the design well thought out, bright, and spacious. I like that. The kitchen is deliberately placed, and the flow of daily tasks is well considered. On closer inspection, I notice that the drainage of both bathrooms runs through the living room. Considering that the wastewater pipe runs completely under the house through the perimeter development in the north (or am I making a mistake and worrying unnecessarily because of the basement?), this is not ideal. I assume this planning in the upper floor is due to the windowless north wall/boundary development? Without implying that all thoughts have been fully considered, I would make the following suggestions: 1) consider whether the upper floor, in its size, makes the house appear too bulky, 2) rotating the staircase, for example, by 90 degrees, might result in a somewhat better floor plan. I just noticed that the basement has a bathroom in yet another location. Whether that is wise... I could imagine that a garage and short driveway in the north with this recess you planned in the southeast, then behind the garage in the north as a kind of small back/front courtyard with an entrance, would give a bit more flexibility towards the south, and there in the south a half-sided overhang of the upper floor, e.g., towards the southeast, would be a bit more pleasing. If desired and I can find some graph paper, I can also sketch that.
