That sounds fun! This kind of stove doesn't warm the kitchen because the hearth is small and the building uninsulated. It probably wouldn't be hard to build one, but the chimney would be harder work.How I covet the notion of a kitchen and a stove designed for wok cooking.
That's getting close to a bushcraft base camp.
I use 3, my best oldest is nearing 50 yrs. +40C or hotter in the kitchen, what's another degree or two?
