Full-bed stone is natural stone cut or selected to its full natural thickness, typically several inches deep, and set as a structural, load-bearing wall rather than a thin surface veneer applied over a separate structural wall.
Unlike thin veneer, full-bed stone carries real weight and is part of the structure itself, not just a face over it. It gets laid in mortared courses or dry-stacked, and it's the traditional method behind standalone stone walls, stone foundations, and solid masonry chimneys where the stone is doing structural work, not just covering something else that is. Because the full thickness of the stone is exposed on both faces of the wall, there's no backing material to hide behind if the joints aren't tooled well, so the workmanship is on display from every angle, inside and out, which is a different level of accountability than facing a wall that's already framed.
Because it's load-bearing, a full-bed stone wall needs a proper footing dug below the local frost line, the same requirement that applies to any structural masonry in this region. Skip that, and freeze-thaw cycles in the ground under the wall will heave and crack it over time, no matter how well the stone itself was laid above grade. That's true whether the wall is a chimney, a standalone garden wall, or the foundation of the structure it's holding up, and it's a step we never shortcut regardless of how solid the ground looks on the surface before digging starts, since the failures that show up later trace back to what happened underground first.
