Traditionally, in Kerala, the art of designing and building of residences remained a hereditary craft, though the related theories did form part of the classic texts. The separation of the craft from the theory relegated house-building as a code of practice to be blindly followed by the artisans.

Manusyalayacandrika of Tirumangalat Nilakanthan Musat (compiled in 13 -- 16th centuries) was probably the first attempt to elevate the house building from the level of a craft to that of a science, synthesizing the science contained in the classical texts with the skills of the silpins or artisans. The uniqueness of Manusyalayacandrika is that it gives a systematic procedure for planning, designing and constructing houses together with ancillary structures [Achuthan, Prabhu, 1998]

The text in Manusyalayacandrika is divided into chapters on: Investigation and Selection of Land (Bhoopareekshaparigraho), Analysis of Site (Vastuvinyasavidhi), Dimensional & Orientation Systems (Manabhedayonyadinirnayam), Layout and Planning of Salas (Salavidhanam), Parts of a House (Gruhavayavavidhayah), Elements of Roof (Sikharavidhayah), and Ancillary Structures (Kavaatabaahyagehakoopadividhayah).
