The layout of a traditional Agraharam house is a masterpiece of linear spatial planning, designed to transition smoothly from public social life at the front entrance to private family domains and sacred spaces deeper inside. Because houses share common side walls along narrow lots, spatial progression moves sequentially along a central axis from front to back.

The Three "Kattus"A classic Agraharam dwelling is structured into three primary bays or segments, known as kattus:1. Public & Semi-Public Exterior (Thinnai)Thinnai (Pial): Raised platforms flank the main wooden entrance on either side. Supported by carved teakwood or stone pillars, this shaded veranda serves as a greeting space for visitors, travelers, and neighborhood gatherings, keeping private family life separate from casual callers.
