This may have been suggested in some form before, Im not sure. I would like for the homes to have a fireplace from which we can cook. With this I would also ask the cauldron be used for non cooking like rennet, silk moths, bone glue... With the fireplace add a cooking pot or cooking cauldron attachable to the fireplace. Since I am on cooking a oven for homes would be nice as well.
I like the idea of building these after the house is built. Collecting stone for a fireplace and chimney. Metal for the new pot. Maybe even clay for the oven. All in all a proper kitchen area would be nice addition.
