Rumah gadang (Minangkabau: "big house") or 'rumah bagonjong' (Minangkabau: "spired roof house") are the traditional homes (Indonesian: "rumah adat") of the Minangkabau. The architecture, construction, internal and external decoration, and the functions of the house reflect the culture and values of the Minangkabau. A rumah 'gadang' serves as a residence, a hall for family meetings, and for ceremonial activities. In the matrilineal Minangkabau society, the 'rumah gadang' is owned by the women of the family who live there; ownership is passed from mother to daughter.
The houses have dramatic curved roof structure with multi-tiered, upswept gables. Shuttered windows are built into walls incised with profuse painted floral carvings. The term 'rumah gadang' usually refers to the larger communal homes, however, smaller single residences share many of its architectural elements.
