Hello, kmschaefer628 - thank you for your question. We are getting back to active monitoring of the Houzz account after a bit of a hiatus, and I apologize for taking so long to get back to you. As to the firewood niche, we coordinated its height and width with the concrete block module - and those blocks are 4" high X 16" long. This means that the niche is 16" wide and 40" tall (ie one block wide and 10 tall). Its depth is approximately 2'-8" (32"). That is deeper than you would tend to need for normal-sized logs, but it resulted from the basic structure of the chimney. I think you could do well with a depth of 24" or even somewhat less.

I hope this helps - let me know if you have additional questions.

Best of luck with your project.

Yours,

Paul
