===Law of original consolidation===
This law makes the distinction between architectural stratigraphy and all other types in regard to three criteria:<ref name=Harvey>{{cite thesis |last= Harvey |first= Heather Maureen |title= Imaging and Imagining the Past: The use of Illustrations in the Interpretation of Structural Development at the King's Castle, Castle Island, Bermuda |year= 1997 |page= 20 |publisher=[[College of William & Mary]] - Arts & Sciences |location= Williamsburg, VA |series= Dissertations, Thesis, and Masters Projects.

#When intact, architectural stratigraphy is of consolidated nature, as opposed to the loose or scattered below-ground remains. Erosion causes parts of buildings to become part of soil stratigraphy.<ref name=Harvey/>
#Architectural stratigraphy is characterised by human intentionality, which is only seldom the case with below-ground strata.<ref name=Harvey/>
#Gravity: architectural stratigraphy left ''in situ'' is ''pulled down'' by gravity, in combination with human or natural intervention, while below-ground stratigraphy is ''created'' by gravity. As a result, architectural stratigraphy scatters with time, the oldest parts being those which resisted the effect of time.<ref name=Harvey/>
