This is a 3d mockup of the eventual appearance of the north wall of the Salon. This is what will replace the wall which is being partially demolished in the photos at the bottom of this post. A new concrete footing will be placed. A lightweight insulating concrete wall will include 2 book alcoves and a spot for a gas heater in the middle (flue not shown). I am retrieving one of the granite blocks from the existing wall to use as a lintel over the gas heater.
Removed the formwork from the new footing and cleaned up.

In the last few days I cleaned out the footing area at the base of the north stone wall. I got rid of all loose material. They I set a form board across the front edge for the new concrete base. I laid a heavy plastic sheet to block moisture from coming up from the ground. Moisture will inevitably rise up. But with this sheet under the slab the moisture will follow the path of least resistance and evaporate through the outside wall, rather than into the house. After placing some of the concrete I set a light gauge mesh of steel reinforcing. This sill minimize shrinkage cracking of the concrete. Finally I placed the remaining concrete, level to within a few millimeters in every direction.

Here is a collage picture showing the north wall of the salon, which I have partially demolished and will rebuild (2013).
