Good example of breezeway idea. I don't like the look or function of an attached garage, but I like the breezeway concept. It acts as a mudroom and a good connection between the house and cold/smelly garage.
My older two boys share a room and sleep in bunk beds. Since we moved them to bunk beds it's been great as it has opened up a ton of space in their room for quiet time away from the chaos of the rest of the house. I love bunk beds.
