Giving a rustic impression, it is strongly recommended to use wood floors. No need to tear down whole floor, just cover it up with wooden floors. Choose white color on the living room wall. You can also cover the wood floors using a medium-sized carpet with rustic motif or farmhouse theme.
On the sofa, you can also cover the sofa up with a fabric. Let it be natural. In this room, give a large chandelier so that the room looks more luxurious. As a room border, use a large sliding door. Natural colored wood doors are the right choice as a complement to this room.
