Overhang (architecture)

The overhang above, 16th century Tomb of Salim Chishti, Fatehpur Sikri, India

An overhang in architecture is a protruding structure which may provide protection for lower levels. Overhangs on two sides of Pennsylvania Dutch barns protect doors, windows, and other lower level structure. Overhangs on all four sides of barns is common in Swiss architecture. An Overhanging eave is the edge of a roof, protruding outwards, beyond the side of the building generally to provide weather protection.

History

Overhangs of the White Palace in the Potala Palace complex. 1649, Tibetan architecture

Overhangs are also common in medieval Indian architecture, especially the Mughal architecture (16th -18th century), where it is known as Chhajja, often supported by an ornate corbel and seen in Hindu temple architecture as well. Later it was adapted into the Indo-Saracenic architecture which flourished during the British Raj.^[1] Extensive overhangs are incorporated the early Buddhist architecture, seen in early Buddhist temples, later became part of the Tibetan architecture, Chinese architecture, and eventually the traditional Japanese architecture, where it became a striking feature.^[2]

It was one of the most common features of American colonial architecture of New England and Connecticut, starting 17th century, which had an overhanging second story, called 'jetty' then, which usually ran across the front of the house, sometimes around it. Then in early 20th century it was adapted into the Prairie School architecture, with architects like Frank Lloyd Wright^[3], and thus made way into the modern architecture as well.^[4][5] An overhang may also refer to an awning or other protective elements.
