there fire pit is nothing more than than there country manor caps glued together. It is not what the catalog displays. They show the celtic wall with a cap. They do not sell the celtic wall buy the piece, and you only need 1/3 to 1/2 the cube to build it. You will also need to do a fair amount of cutting.
The fire box kit is the pan, cover , fire bricks, and stone dust and runs around $450.
It takes 12 country manor caps per layer.
hopes this helps
