Ettukettu is an example of the traditional style of architecture of Kerala
. 'Ettu' means 'eight' and 'Kettu' means 'built up sides.' Ettukettu is the house with two quadrangles or mansions with eight salas (square or rectangular living rooms with verandahs on one or more sides) around two courtyards.
The ettukettu is a unique and distinct style of construction. Ettukettu is laid and constructed with rituals and principles according to the Vaastu Vidya. The laws bind everything from selection of site, nature of soil, orientation of buildings, to position of the buildings and rooms. The ettukettu model houses demonstrate excellent craftsmanship in wood, and a good understanding of construction and building material science. Tripunithura Palace is famous for its ettukettu, designed by Velanezhi Jathavedan Namboothiri.
