It is possible to add a stone wall between kitchen and dining areas that have cooking ovens and a fireplace. The fireplace and oven(s) will require surrounding insulation. If the point is to have pass-through warming areas in the wall, you will need custom work. This could certainly be accomplished by insulating the existing wall between the rooms, cutting openings for everything and building a stone wall on each side of the wall. The weight might require structural reinforcement. You could also tear out any existing wall, build a stone and mortar wall with openings for the areas you want. The least expensive approach would be to use prefabricated stone wall units. These consist of 1.5 to 3 inch pieces of rock and mortar attached to mesh. They would be attached to the wall as a rock facade. If you used a one-sided oven (I am not aware of any pass through ovens available today), a zero clearance gas fireplace and rock facade on a standard stud/drywall wall, the cost we be anywhere between $2,000 and $4,000. The price would depend on the size and the type of fireplace and rock facade, and the size of the wall. This price does not include the oven.
