For some reason, I love houses that have little to no hallways. My Grandmothers house that was built by Grandpa himself during the Depression had no hallways & all the floor plan flowed. My parents house had a small hallway, if you could even call it that, which was connected to the living room through a good size arch. The two bedrooms were on each end with the bathroom between the two. My parents turned what would have been nothing but an attic you got into through the hallway ceiling into a third bedroom which was huge. You got to it from a door in the living room & put in a set of stairs going up over the set of stairs that led to the basement from the back door.
Hope that made sense.
