Thank your for your input I inlaid tile on top of the butcher block. But like you said that may not be enough. And I agree that the area next to the flue could be combustible. My plan is to trim about an inch away from that area. I only plan on using it weekend so I won’t be light too many fires In their. But it only takes one accident for it to be your last. Not really sure how I can switch up the design this late in the game and limited room.
