Convert a deep closet into a hideaway space. If you don't need the closet in a home office or guest bedroom, turn it into a sitting area. Take off the doors and add built-in drawers across the bottom of the closet to create a bed-height bench and provide extra storage. Install good overhead lighting and shelves for books, then paint the interior and trim in a warm color. Throw pillows that invite family and friends to sit, read and relax finish off the space.
