The project divides the spaces separating them from day and night areas.
I propose to take advantage of the light in the second floor, the big windows will light up your living area.
You can use the first floor for the night spaces: a big bedroom with a beautiful walk-in closet and a comfortable bathroom, while in the entrance you can find a storage area and the space for the washing machine.
For the stairs there is a little modification, but only for the last stairs due to increase the airiness of the room.
