Hi Faye, that is a nice layout for a studio unit. But, hopefully you can give us more pictures of the room. A clearer view (with like where windows are and etc.) could help us generate better ideas for you. Looking forward to help you! :D Also, if you don't mind me asking, do you entertain guests in this studio? (You know, for considering seating options, dining, bed and etc.)

Try googling "tiny house" to see a lot of ideas for small spaces. Use the wall opposite from the bathroom for shallow storage. Try using Ikea's NORBERG as a table/work surface for your kitchen; set it at 36" above the floor and get 30" stools. I noticed that there are 0 closets. Perhaps purchase a wardrobe and place it next to the refrigerator. If you are placing your furniture as shown, switch the sofa to the other wall so you have full clearance of that door.
