Rumah Gadang

The rumah gadang ("big house") is the traditional family house of the Minangkabau people of West Sumatra, Indonesia. Its roof is the most famous part: a sweeping, saddle-shaped form whose gable ends rise into sharp points called gonjong, which are said to recall the horns of a water buffalo.

The gonjong roof

The roof has multiple tiered, upswept gables. It is built with truss and cross-beam construction from many small battens and rafters that together produce the curved profile. Unlike some neighbouring traditions, such as Batak Toba houses where the roof itself forms the living space, the Minangkabau roof sits on conventional walls.

The points are made of thatch bound with decorative metal and drawn up into spires. The buffalo-horn reading connects to a legend about a contest between two water buffaloes from which the Minangkabau name is thought to come; the upward peaks are also described as reaching toward God.

Ijuk thatch

The traditional covering is ijuk, the black fibre of the sugar palm, laid in bundles that follow the curves of the roof. It is regarded as one of the toughest thatching materials available and is said to last up to a century. Today many houses use corrugated iron instead of thatch, which keeps the silhouette but changes its texture and acoustics.

Society and the house

Minangkabau society is matrilineal. The house belongs to the women who live in it and passes from mother to daughter, while the senior male relatives of the lineage (ninik mamak) are responsible for building and maintaining it. A rumah gadang is ideally accompanied by rangkiang, raised rice barns with the same horned roofs.

Landmark example

The Pagaruyung Palace (Istano Basa) is the largest and most elaborate example of the style. Unlike an ordinary rumah gadang, it is built on three levels. The gonjong roofline has become a widely recognised emblem of Minangkabau identity.
