What definitely does not work is an attic conversion with a staircase.
Why the main bathroom does not have a shower is also beyond me.
And I personally find the sofa position more than uncomfortable right in the middle of the room, visible from the front door. And the kitchen is rather impractical to furnish, with long walking distances, or as drawn no space between the sink and the stove.
I find the terrace corner too small for meaningful use. If you put a table with only 2 chairs there in such a way that the rain does not hit it, the exit is almost blocked.
The utility room is quite small, but there are, partly as in the living room, areas that are somehow unnecessarily large.
Unfortunately, there is no site plan to see how the house fits onto the plot, where the carport or similar will be.
I think there is still room for optimization.
