-You should at least make the joints as thin as possible, 1/4 or so.
I understand what you're saying and you can lay them tight with refractory mortar, but you cant lay a solid firebrick that tight with regular mortar. You would have to shake your regular mud so thin it wouldnt be any good and couldnt get a good looking job that way.

The joints on this box is 3/8" and I know I build fire boxes differently than our friends up north but this style of box works great and I never had any trouble of box burning out.

I have seen a lot of block foundations, but have never seen one with the firebox laid up that early. We are always under roof before they come back and lay that up.

In this case, I have two intersecting walls with a tri-angle chimney base and a thimble and flu on the back side. Just make since to get the fireplace and chimney base done before they start framing.
