Building a stove in my fireplace

Hi!

I am trying to prepare my suburban home for a possible extended grid-down situation. And try to just be more self-sufficient in general.

I have a small fireplace. Right now it is gas, but I plan on having it capped off to be wood-burning. It is masonry and, I presume, was originally wood-burning. I want to have a plan to set up a temporary stove for cooking in there that will also do a better job of heating the room in an extended grid-down situation. I do love the look of the fireplace now, and was hoping to not have to do anything permanent so I could use the fireplace for ambiance.

I thought I could just build a rocket stove in there with some firebricks, but upon learning more, I was concerned about drafting and creosote buildup.

Could anyone share a plan for a safe, temporary firebrick stove setup?

Fireplace dimensions and photos:
Opening: 28" h x 32" w
Footprint: Trapezoidal. 32"w x 17d. Back wall is 20"w.

I don't believe it has a steel liner.

TIA!

If as you say, your fireplace was originally a wood burning fireplace with a chimney then you can use it to burn wood under certain circumstance.

By changing it to a firebrick wood stove are you violating code?

If you add a temporary firebrick wood stove wood you use the same chimney or add an additional chimney?  Is an additional chimney possible?

I would suggest having a professional inspection, capping the gas line, and ensuring a proper chimney liner if using the same chimney.
