I've been wanting to install a firepit for a client for a while but I've never really pushed it because I am not confident we could do one correctly, having never done it before. So I've been looking for a guinea pig to test our skills on. And our office manager, who hired us last year to install a nice flagstone patio, said he'd volunteer to let us give it a whirl. So now I am just in the planning stage, and I need some help, ideas. I know I could do it with some sort of segmental re. taining wall product. But I was thinking we'd do it in ledgestone - mortared. He wants it to be a gas firepit - one that would use a portable propane tank to fuel it. So I was thinking stacked, mortared ledgestone in a circle. And maybe we put mortar all along the inside walls but the outside we try to keep the mortar hidden as much as possible. Then I have two options for the propane tank. I could either put it inside the firepit, and cover it up with a round metal grate and faux logs. Or I could hide a pipe under the flagstone patio going into the firepit and still have a metal grate and faux logs. But then the propane tank would be 10' away, and the owner could simply disconnect it from the hose, and take it to get refilled, without having to ever open the firepit up. Below are some pictures that sort of represent what I am trying to do. Anyone done this? Have pictures? I am also looking for technique tips for how to build and ideas for where to get the metal grate and faux (ceramic) logs.
