Living room, family room, parlor, playroom, or den.  Breakfast room, kitchen, or dining room.  Porch, sunroom, or sunporch.  Terrace or patio.  Whatever terms you use to describe the spaces in your home, let them reflect you and your family's preferences for how you wish to inhabit them. Just because the floor plan is labeled "dining room" doesn't mean you are not allowed to set it up for your children's playroom now and a home office later on.  Let's design with flexibility!
