DNM Architect It is a composite wood, similar to Trex, but another brand. The owners placed the fire bowl on the deck, but I have not heard of any problems. I think the realty is they do not produce that much heat underneath.
A freestanding wood-burning fire bowl is pretty portable. This one is being used in a courtyard surrounded on at least three sides, so it is very protected from wind. A portable fire bowl is also easy to scoot it off to the side when not in use, as I think they did here because it is very close to the shrubbery.
Tip 7: Remember that the metal gets hot. Let it cool thoroughly before attempting to handle the cover or moving the bowl.
