It provides general advice according to different categories of intervention in heritage assets, including repair, restoration, addition and alteration, as well as on works for research alone, based on the following types of heritage asset: buildings and other structures; standing remains including earthworks; buried remains and marine sites; and larger heritage assets including conservation areas, landscapes, including parks and gardens, and World Heritage Sites.
