I have a fireplace that is no longer functional that I'd like to remove (pictured below). It appears to be a steel insert, which covers the brick. The chimney has been removed down to the top of the first floor ceiling, to make room for an addition upstairs. Does anyone have any ideas what kind of work I'm getting into? I'd assume that I'll be knocking out the brick that's inside the fireplace, but I'm not sure how the steel insert is removed. Then I'm looking at some drywall work and finishing the floor underneath the fireplace.
