It started off as a firerock fireplace kit and I added about 100 concrete blocks to it to give it some mass and aesthetic appeal.......i have been working on this for approximately 2 weeks.......I started off by digging a very large footing, inserting rebar and then i had a concrete truck come and i made approx 40 trips with a wheelbarrow back and forth to the concrete truck , dumping the concrete in the footing......i didn't have to go to the gym that day......i then had to take a break for 4 days while a crew of guys laid down pavers......the pre engineered fireplace kit assembled like legos.....and now im finishing it up with stone veneer.....a lot of work.
