Except for the windbreak, I really like the floor plan! In the living room, you could rotate the sofa 90° clockwise and plan a wall panel as a room divider to the dining room, on which the TV is mounted. That way, it wouldn’t be a problem that the living room turned out a bit narrow.
Why did you plan only a single floor-to-ceiling window in the whole house? The views seem a bit too uniform to me. But of course, that’s a matter of taste.
Otherwise, really nice! Especially the kitchen/dining/stairs area.
