I see insulation on the interior of the foundation walls. Nice!
You are making TOTAL sense. I eat this stuff up.
Now for the dumb question of the day.
Why did you step the foundation down to the exact width of the floor plates. Why not just butt the outside edge of floor plate up to the exterior edge of the foundation?
It looks like they put a foundation in to support the weight of the structure and then put a retaining wall on that to hold back the soil.

I need to read up about pouring foundations I guess...
