Hi has anyone had a go at making something on these lines?

I am looking for a rocket stove/rmh design with a small footprint. I was wondering about different types of bricks and their thermal properties as does it need low thermal capacity in the burn chamber but high on the exhaust side?
I'm thinking of cob around the outside to seal it and make access holes to clean out ash and light the fire, also seal in a hot plate? Maybe even going up the flue to increase the thermal mass?

I've been given a stack of bricks from a storage heaters. I have no idea what they are made of but can I use these or are they probably not high temp proof.
I'd be grateful for any comments as I am just learning about rmh designs.
