try Benjamin Moore Key Ivory West for the walls - it's a soft color and will brighten the space, but will work with other colors. Put a funky rug on the floor. Go to Marshalls or TJ Maxx or IKEA and get a comfy chair with a a small table next to it. If she has any artist friends at school, have her ask them to do an oil or watercolor of something she likes in a large canvas for over the bed (don't frame it). Replace those lights. Or, for over the bed, just print out a bunch of 5x7 photos of friends or whatever (black and white would make a statement) and arrange them in whatever frames you like. Going for neutral or soft colors will enable you to use accessories for color and change the look when it gets old.

Thanks Carole, yes we are very keen to knock out that wall - I have to be restrained from bringing the sledgehammer inside until we get a proper load-bearing beam organised! Once thats done and the books are off the floor and on the wall opposite we will have to think of rearranging this space - I still like it split up by a couch, but perhaps we could put a larger dining table in the new space.

I would use a bookcase unit with closed doors on the lower half and not too high. Wide and low maybe. Closed lower cabinets are great for toys, games and will not clutter. Open shelves tend to get cluttered after a while. When displaying books, use in stacks standing and lying down. Open space between groupings, not all lined up in rows. Add some decor items sprinkled among the books to give the eye a visual break. I would choose a horizontal art piece for the chair wall. Add some art on the long TV wall leaving a lot of bare wall between the TV . and the artwork between the corners of the chair wall and the window wall.

Well, for lack of a better idea, since you find it a drafty little space. I'm assuming the draft comes in on the right? Most of the necessities in the area are located of the left side; i.e. vent, thermostat, light switch etc. What I would do I think is caulk up the drafty spots, maybe even add sized poster board wrapped in batting I covered in a gorgeous fuscia with diagonal grosgrain ribbons every which way covered with a heavy velvet to be attached to the area above & below the window. (Of course remove the drapes that are hanging in there). This for the purpose of using it as a pin-it board for notes. Attach a table height board covered in felt to carry across the full width of the little room. Leaving just enough space for a comfortable little antique desk chair. Paint the back wall a bright cobalt blue, paint the ceiling a silvery pearlescent white. Find a way to attach a clip-on task lamp. And stretch a heavy duty enough wire across the top of the opening and complete it with a heavy doubled velvet drape with a drooping valance. Place a swag with fringe & jewels on it to be closed when not in use. Voila intrigue is yours!
