Rumah Bubungan Tinggi or Rumah Banjar or Rumah Ba-anjung is an iconic type of house in South Kalimantan. Its name Bubungan Tinggi refers to the steep roof (45 degrees). In the old kingdom time, this house was the core building within a palace complex, where the King and his family resided. Since 1850, there were various buildings added around it with their own respective functions. Later this type of house became so popular, that people which were not part of the royalty also took interest in building it.
Today, there are houses of this type of architecture all over South Kalimantan, and even crossing the borders of Central Kalimantan and East Kalimantan. As it is more expensive than a usual house, it is only affordable for the more wealthy people.
