ᐅ Bungalow Floor Plan with Gable Roof – Potential for Improvement?

Hello
Attached is our floor plan for a bungalow with a pitched roof (storage space under the pitched roof).
The kitchen and bathroom fittings are yet to be planned. Only the room sizes are defined. Doors can still be moved slightly.
At the staircase area, a small entrance hall can optionally be installed (less heating required). The terrace will be semicircular at the front, so slightly larger.
The main focus should be on interior optimization.
The maximum width of the floor plan is fully used – unfortunately. One meter (about 3 feet) more would have been better.

What else could be improved?

I have attached the plan as a PDF and JPG.

Thanks
