ᐅ Floor plan for a hillside house with an integrated garage

Hello,

here is the floor plan for our house for discussion and constructive feedback.

Thank you

A bit hard to read.
On the ground floor, you have two hallways one after the other, right? First into the entrance area, then to the right into the living area? What is the purpose of the second hallway going all the way to the exterior wall? Between the bathroom and the one room.
