Hi dear client!
This solution is simple, I intervened in the girls room with a glass door and a little gypsum wall. I demolished the kitchen wall, let the kitchen in the same place, so you don't need to change the pipe and next to the bathroom. A little additional gypsum walls at the second bathroom to have a nice space with all the equipments. This solution let's you to spend more much many in furniture, materials and furnish your home and less in division of the spaces.
Day area.
Kitchen model is with a peninsola with 2 stools for a fast breakfast.
A big table for six persons and a grand sofa for all your family.
Girls bedroom
I choose this kind o solution to have natyral light even in the first semi room. This solution is to have each of the girls their own corner and private space.
Hope you enjoy the project!
