Clad in Wood
This firepit was made from concrete blocks, and then clad in wood to match the surrounding planters and decking.
The top was made from the same stone as the patio.
Notice the small ventilation slots at ground level. There were 4 slots, and although they added up to less than recommended, the customer has not reported any problems, so it must be working fine.
All it needs now is some seats, people, wine, beer and you have yourself a firepit party.
