My buddy Dave builds theses... We used to build them together for extra cash together while in college.
I cant find any fire pits that we built on my computer...But heres a few Islands and Fire places we did at way less cost to the customer company we worked for.
Our build time was usually a week..I think he's still getting them out that quick. Free Delivery too...I think.
Let me know If you would like his contact info.
The one that Madelon posted above is something Im gonna just do myself for the river house.
