A new cozy home for 3

Greetings!
For designing your space i have thought of creating a space with abundant surface with as few unusable spaces as possible.
A priority has been given to the living room and the dining room. I have designed a place for putting children's toys and there has been a surface of 9 m2 created as a personal studio.
I wish for my design to allow you to move freely and also to allow you to have a quiet place to live in.
