Not that I have an empty closet, but i do like this."Closet Office" - Turn your un-used closet/reading nook into an office space. Maximize the little space with lots of shelving and storage *LIKE CORNER DESK/nook & shelving for office corner
I think this was designed for a pre-teen/teenager, but there's a lot I like for a guest bedroom/home office. Love the built in desk and storage and love the blue, white, bright green color palate. The ceiling fixture is especially cool.
