masonry for outdoor fireplace
this is example of fully flush fireplace which we don't want but as a point of reference: what about taking the fireplace face up to "mantel height", then jutting it back (recessing) a bit (with possibly that black decton as a surface? and coming "out" just a hair) then back up the wall and maybe an additional recess another 18-24 " higher
note the recession from the front of hearth tapering back. maybe you put 2 levels of mantel. so it's not as imposing
