However, different regions and countries have their own words for over-hangs. In the United Kingdom, they are often called eaves or roof eaves. Australians refer to them as verandas or awnings while in the United States, they may be called rafters or soffits. Other synonyms for over-hangs include cornices, gables, canopies, and hoods. No matter what you call them, these features continue to play an important role in architecture and building design.
