I am moving into a house that has an existing working chimney and holes cut into the walls in the living room and kitchen for the pipe for a wood stove. I know the chimney is good because I just bought it and the previous owner used a wood stove last winter. How could I put a fireplace in rather than a wood stove. I have a wood stove, but would like to have a fireplace in the living room. Can I build a fireplace there?
I would STRONGLY suggest finding a "fireplace format stove" you are kinda happy with and stopping right there. Retrofitting a masonry fireplace is a huge undertaking that generally has to start from below the basement floor.
I guess a prefabricated metal fireplace in a framed drywall box could possibly scratch the fireplace itch a bit more. Most of those are not compatible with having a second entry to the same flue, so if both the living room and kitchen enter the same flue, you'll have to address that.
