In this design, I moved the kitchen into the room in the center, making it a hub for all activities around the house, connecting between entrance, living area, and the bedrooms.
From the entrance I put a small foyer for transition and privacy before entering the house. This foyer area is useful to put coat / shoe cabinet as well. In the reference image slide, I provided two design options, whether you prefer it to be see-through to the kitchen and get natural light from the window, or if you prefer a more enclosed space with more privacy.
The bathroom location remains the same with the current position, I just changed the layout to make it more space-efficient. But here I also proposed to add another bathroom on the right wing for convenience from the bedroom. However, if this is technically difficult to implement, you can disregard it and keep the current bedroom plan.
