The various aspects of prefabricated building methodologies and adoption of alternate building materials for low cost housing. In a building the foundation, walls, doors and windows, floors and roofs are the most important components, which can be analyzed individually based on the needs thus, improving the speed of construction and reducing the construction cost. The major methods of construction systems considered here are namely, prefabricated roofing components like precast RC planks, precast hollow concrete panels, precast concrete/Ferro cement panels and usage of new alternative building materials like Fly –Ash sand lime bricks, Solid concrete and stone blocks, Cellular Concrete, Laterite Blocks, Dry-Hydrated Lime, Rice-husk Ash Pozzolana and Hollow Concrete Blocksen-USStaff Publication - SoETStaff Publication - CEArticle
