Houzz is the new way to design your home.
Wood and ambers storage
I don't like the stone but the are where the wood is store can be extended to form a seating area with the wood stored underneath it all along the wall
Have the tv where the cabinets are and store the firewood under the fireplace in the "dead" space where the step is
Raised hearth with seating area
Fireplace vs tv
Floating wall could be a fireplace
Low and wide so tv can fit above it.
FP as a room divider. Also see the lower ceiling hieght
