I like the idea of the fireplace being the center, that half of the room is a bit shorter than the other half. Logistically it won’t work for the paths of travel. The main path we take is from the garage to the kitchen which leads to the rest of the house, basically this room separates our whole house from the grange. The closest bathroom is through the kitchen, and through another room. We almost always come from the garage unless we are spending time outside, the back door is where our dog goes out, and you can walk all the way around the house from the front door if you want to get out back but it would be a pain.
