As it is visible on the photos the walls of house is made from stone, so I didn't removed any of them, just made 2 opening in place where is the corridor. I did the small bedroom in the middle space and on right side on a drawing because of sun position . ( By this way bedrooms have windows on East - South for better day light. ). Bathroom and Laundry are on the other side which is North. Flat is not too big but it has good planing distribution now. I also made window in the kitchen twice bigger for better day light.
