Does the fireplace go up to the ceiling?

The fireplace does have brick that goes up to the ceiling but/and for better or for worse we have a tv mounted above it which will remain. Thanks for any input!

how many people use the room, usually? activities besides TV that you/family rather do there? games, books?..asking because furniture must reflect your needs and lifestyle. storage-how much of it. a table(besides a coffee one/ottoman/etc)-whether needed and what size if yes..

Thanks -- typically two adults and two young children. Occasionally, two additional adults such as grandparents visiting. The room is generally used for tv and reading (we have a separate "formal" living room and dining room). Storage is not a concern.

Are the openings actual doors or just openings? Where do they lead?

The one in the corner is a folding door into the kitchen (folds on the kitchen side) and the other are folding six panel doors (fold into the family room) a hallway with powder room/entryway -- it's a traditional colonial house
