We bought our house five years ago yesterday and I picked out which room I wanted to make my studio. Finally, I have finished it and it is a functioning art studio!
Here is the before photo, but to be honest, this is when I had already started cleaning out the closet and shelving units.
The walls were a yellow color which was absolutely horrible! I painted the walls and trim white to keep it really clean looking. Of course I had my little helper with me the whole time.
After I finished painting, I bought a hollow closet door and put white formica board on the top to use as a desk top. My parents gave me an old gray two drawer file cabinet that I spray painted white and used that as the base for the desk on one side. To keep the desk top up on the other side I used L brackets on the wall.
