Hi Edward;
That's a tall order your asking for...
If you use a clay sand mortar to build an oven , then it is easy easy to disassemble.
I say easy because the bricks will pop right apart.
The clay sand mortar will slip right off into a bucket and is completely reusable.
The not easy part is moving 300 or so bricks and bunches of mortar.
I just built a super awesome Black or white
Rocket powered oven.

It works great, took just over 300 bricks.
Plans were purchased from Matt at Walker stoves.

Good Luck with your build!
