Indonesian architecture

The architecture of Indonesia reflects the diversity of cultural, historical and geographic influences that have shaped Indonesia as a whole. Invaders, colonizers, missionaries, merchants and traders brought cultural changes that had a profound effect on building styles and techniques.

Numbers of Indonesian vernacular houses have been developed throughout the archipelago. The traditional houses and settlements of the several hundreds ethnic groups of Indonesia are extremely varied and all have their own specific history. The houses hold social significance in society and demonstrate local ingenuity in their relations to environment and spatial organisation.

Traditionally, the most significant foreign influence has been Indian. However, Chinese, Arab, and European influences have also played significant roles in shaping Indonesian architecture. Religious architecture varies from indigenous forms to mosques, temples, and churches. The sultans and other rulers built palaces. There is a substantial legacy of colonial architecture in Indonesian cities. Independent Indonesia has seen the development of new paradigms for postmodern and contemporary architecture.

Ethnic groups in Indonesia are often associated with their own distinctive form of rumah adat. The houses are at the centre of a web of customs, social relations, traditional laws, taboos, myths and religions that bind the villagers together. The house provides the main focus for the family and its community, and is the point of departure for many activities of its residents. Villagers build their own homes, or a community will pool their resources for a structure built under the direction of a master builder and/or a carpenter.

The majority of Indonesian peoples share a common Austronesian ancestry,), and traditional homes of Indonesia share a number of characteristics with houses from other Austronesian regions. The earliest Austronesian structures were communal timber longhouses on stilts, with steep sloping roofs and heavy gables, as seen in, for example, the Batak rumah adat and the Torajan Tongkonan. Variations on the communal longhouse principle are found among the Dayak people of Borneo, as well as the Mentawai people.
