If the rainy season weren't fast approaching, she would be sitting beside the double glass doors of the kitchen entrance/garden exit.
Below Willy is the 1/4" metal sheet that serves two purposes: it spans the tunnel opening for the foundational wall above it, and it sticks out from the foundation for use as a cooking surface.
Instead of building the foundation walls only from rock, we chose to put one course of rock on the bedrock we are building on. To further minimize the amount of rock needed (we haul it in by wheelbarrow - if we can get it in the barrow - or roll it downhill if at all possible), we only built with rock where water could possibly reach (from a spill inside the kitchen or through the Ondol tunnel). During our last two week-long workshops, we built 18" wide cob walls to bring the foundation all up to grade; this will be a great test to see how any rainwater that gets in runs through the site during the rainy season!
