Every hamlet of the Ba Na has a long house which is made of precious sindora and iron wood. The house frame has no collar beams, only pillars tied to each other by rattan strips and creepers. A normal Rong house is 12 m high, 12 m long, and 8 m wide and can accommodate 80 to 100 people. Some hamlets build their community house as high as 18 m to show off their strength and wealth.
