New build floor plan design

With our architect we're nearing a final design and it's definitely difficult to get everything right. For some things the architect says that it depends on the person on what setup is the best - which kinda makes sense still we're afraid to miss any improvements to the floor plan:) It's a west facing plot & we're a family of four.

Do you see any improvements we can still incorporate? E.g. improved layouts/ space for closets, obstructions in movement,.. Many thanks all!

ground floor

First floor

We might switch the proposed bathroom/bedroom to this layout - with the doors on the other side. Although it's farther to walk through the dressing each time- the bathroom layout makes more sense.
