Also on these boards
Wall brackets from hobby lobby and wood plank (see "home/decor") and 4 of the organization boards (calendar, full white board, full cork board, and mail sorter). Instead of books on shelf, add burlap and lace boxes (see other pin). Add filing trunk to opposite wall and mount shelves for printer. Or add filing cabinets and printer on top.
A console table for right behind the couch. Place a lamp on it. Drawers for papers from the kids - "in," "out," "file," etc. instead of a shelf? Bins underneath could hold a selection of board games, coffee table books, throw blankets, baby toys, more video game accessories (I KNOW - we have a lot).
