A few muddy hours later...
Meanwhile up above, E was working with Josh Storer, of Barefoot Radiant Heating Corvallis OR, putting in the first of the pex tubing for the radiant floor heating of the main floor. This is the first time we can really make out the rooms. The tubing already laid down is in the kitchen floor.
E, I suspect, showing Josh the troubles were having setting grade around the step-down into the great room.
Getting it right.
