TheEast Asianhip-and-gable roof (Xiēshān (歇山) inChinese,Paljakjibung (팔작지붕) inKorean andIrimoya (入母屋) inJapanese) also known as 'resting hill roof', consists of ahip roof that slopes down on all four sides and integrates agable on two opposing sides.^[2][3] It is usually constructed with two large sloping roof sections in the front and back respectively, while each of the two sides is usually constructed with a smaller roof section.^[4]

The style isChinese in origin, and has spread across much of East and Continental Asia. The original Chinese style and similar styles are not only found in the traditional architectures of Japan, Korea, and Vietnam but also other countries such asMongolia,Buryatia,Kalmykia,Tuva,Bhutan,Tibet andSri Lanka. A similar, generally taller and originally thatched hip and gable style is also traditionally used in Southeast Asia such as in the Philippines and in Indonesia.

It is known asxiēshān (歇山) in Chinese,^[5][6]paljakjibung (팔작지붕;八作지붕) in Korean.^[7] andirimoya (入母屋) in Japanese,^[3]

In China, the hip-and-gable roof style, also known as thexieshan roof style, is thought to be invented by Huang Jieming, a Chinese inventor from theEastern Han dynasty, as an adaptation of thehip roof. It was mainly applied in the construction of palaces, temples, gardens and other buildings with official functions. In contemporary times, it is still widely used in Buddhist and Taoist temples and shrines in China.^[8]

The style is generally characterized by the presence of nine ridges and ahipped roof encircled with aperistyle. The nine ridges typically consists of one horizontal ridge on the top, known as the main ridge, which is connected to four vertical ridges and four diagonal ridges. 

There are typically two types ofeaves associated with the xieshan style: single eaves (单檐) and double eaves (重檐). Single eaves refer to the edges of a basic xieshan rooftop, while double eaves consist of an additional layer of eaves below the basic xieshan rooftop. Examples of the double eave type can be found on the xieshan roofs of structures such as Cining Palace, theGate of Supreme Harmony and theHall of Preserving Harmony in theForbidden City, as well as theGrand Hotel inTaipei. Examples of the single eave type can be found on buildings such asZhihua Temple, theshanmen ofMiaoying Temple, and the North Gate of theWalls of Taipei.

Paljakjibung(팔작지붕) is the most commonly used roof type in authoritative architecture during theJoseon Dynasty. Considering that the hierarchy is the highest, regardless of size, most of the central buildings are Paljak. However, in temple architecture in the late Joseon Dynasty, where wood was scarce due to the high demand for wood used for roof furniture, the lower furniture was left intact and only the roof was often replaced by the eight-piece.

Irimoya arrived from China to Japan in the 6th century.^[3] The style was originally used in themain and lecture halls of a Buddhist temple compound. It started to be used for thehonden at shrines and also in palaces, castles, and folk dwellings later during theJapanese Middle Ages.^[9] Its gable is usually right above themoya, or core, while the hip covers thehisashi, averanda-like aisle surrounding the core on one or more sides.^[3]

It is still in wide use in the construction of Buddhist temples and Shinto shrines in Japan. It is also often calledmoya-zukuri (母屋造).^[3] Another variant of Japanese hip-and-gable roof is the Shikorobuki.

In Sri Lanka, a style known as thekandyan roof bears many similarities to the original East Asian hip-and-gable roof. Thekandyan roof is primarily used for religious, and historically, royal buildings. Its roots however lie in the traditions of the "Sri Lankan village".^[10][11]
