Brick and clay fireplace.

Hello again. I will need some advice regarding planing for a fireplace.
So please let ignore the regulations for a moment and try to make a theoretical exercise.
Let's say a wood cabin with an internal fireplace on the middle internal wall (or close to it). All the smoke will exit the attic an it will be use to preserve the shingles and smoke meat.
I have attached below scheme.

The legend is red-brown line are brick, black line is the smoke chamber (steel sheet welded) and the smoke pipe. Blue parts is where the interested bit comes, I'm thinking a metal frame welded (a scheleton box) and covered on the sides with chicken wire mesh and plaster with earth and straw. There are two kind of this boxes one on top of another. Everything is plastered at the end with clay and limewash.

Is this a achievable plan? Do anyone has any experience with cob fireplaces and plastering a wire mesh?

Thank you.

Have you looked at old images of these?
Do you really need the mud?

Yes I need the clay/mud because I'm copying a museum one. But that one has wood in it's core structure and wood planks for it's smoke chamber:) which for me is a no no.

From the site that you have pointed mine is at the "“Stube” the beginning of the 16th century from Fränkischer Frelichtmuseum" tiled stove but without tiles, level.

Too dangerous a situation.  Nifty idea.

Smoke sometimes has ember that might catch the attic on fire.

Mr Google said,  The height creates a stronger draft, which improves airflow and ensures efficient combustion, preventing smoke from backing up into the house. A chimney that's too short can lead to inadequate venting, fire hazards, and poor air quality

In this case I will extend the chimney to exit the roof.

I'm more interested on the technical bit of the fireplace construction.

Mr Google says, A chimney should extend at least 3 feet above the roofline where it penetrates and be 2 feet higher than any part of the building within a 10-foot radius. This 2-3-10 rule is crucial for proper draft and to prevent smoke and embers from being drawn back into the house or onto the roof

From wikipedia
"It is a room heated by a large stone- or tile-covered stove and entirely lined with wood to keep the heat inside;
the woods mostly used for the wall panels are chestnut, walnut, spruce, and Swiss pine.
The logs are inserted into the stove through a small door that opens on an adjacent room, usually the kitchen or the corridor."
That does not match what you were talking about,
