In this layout the traffic flow is circular, from the front door through the living room to the dining room to the breakfast area and family room and then back to the foyer. The kitchen connects to the garage through the utility/laundry.
Is there room for furniture around it? I like the way the great room fireplace in modern prairie style, below is part of a wall with built-in storage for media and books. A fireplace too close to a doorway is not very useful.
