While many think of a family living room decorating theme as one with board games, and fluffy carpet, it can be much more. Family oriented living room decorating themes are common in home based decorating circles, and frequently are similar in looks. In order to accommodate a family you must have an area for everyone to sit. For this particular theme, you should center on making the sofa as large as possible, with as much room for family as needed. Using the sofa as a design anchor, the rest of this family area decorating theme should fall into place.
