Great room floor plans offer a common space in the house plan for families to gather or to entertain guests. They may include a fireplace, vaulted ceilings, or built-in shelves for storage. The great room is one of the most lived-in rooms in your home. It is a space to gather with family and friends and to enjoy conversation, watch movies, play games, or simply relax with a good book. Modern floor plans are designed with an open concept, creating a natural flow between the kitchen, dining room, and great room.
