A kuti is a small structure, built on stilts, designed to house a monk. Its proper size is defined in the Sanghathisep, Rule 6, to be 12 by 7 keub (or 4.013 by 2.343 meters). This tiny footprint is intended to aid the monk's spiritual journey by discouraging the accumulation of material goods. Typically a monastery consists of a number of these buildings grouped together on a shared terrace, either in an inward facing cluster or alined in a row. Often these structures included a separate building, called a hor trai, used to store scriptures.
