Dear Emanuele, my vision of your new home was to make a comfortable place but respecting your wishes. You give to me one good suggestion: to displace a door of the guest bathroom, from front to facing the kitchen space. And that will be the first step to make storage place with washing machine and small sink on left side and keeping the toilet on the right side. Second, you ask for more light in your bedroom. I give you the best solution: remove the wall and put just a 150 cm high wall in front of toilet and you will have the all light from that window. In this way, the space is enough for nice jacuzzi tub. Behind the big double bad I put the same high wall. Behind that wall I make the walk in closet. On the other walls I combined wall grey wall paper and light gray colored walls. In living room, when you come in, on your right side I put a nice wood working desk with two open shelves and your picture on the center of that wall. In front of the desk I placed the shelves with glass door for your books. Also, the red open shelves are all around the open space to make connection with all areas (living, dining, working, kitchen,...) Between kitchen and working area are the living, TV place with big orange sofa and two contemporary arm chairs and big low coffee table. Behind the sofa I put one more shelves with glass door for your books. On the left side, in front of the storage wall I make a dining area with big interesting dining table, six chairs and one big wall clock. On the wall I put 3D wall paper with all color palette from the room and on the windows, silver windows shades.
I hope you will like your new home.
Iris.
