On a lot that drops toward the Kennebec, the garage foundation steps down with the ground instead of fighting it. We pour the frost wall in stepped sections so every footing bears on firm soil below frost, then backfill and grade so the slab lands at the height the house door needs.
Where the garage joins the house, code calls for a fire-rated separation, so the shared wall gets rated drywall and the connecting door is a fire-rated unit. We tie the new roof into the old with flashing that sends meltwater away from the seam, which matters on a shaded slope that holds ice into April.
