It have registered amplification of up to 15 % every year, mostly due to cost of basic building materials such as steel, cement, bricks, timber and other inputs as well as cost of labor. Consequently, the cost of construction using conventional building materials and construction is becoming further away than the affordable limits particularly for low-income groups of population as well as a large division of the middle – income groups. Hence, there is an urgent need to adopt cost- effective construction methods either by up-gradation of traditional technologies using local resources or applying modern construction materials and techniques with efficient inputs leading to cost-effective solutions. This has become the most relevant aspect in the context of the large volume of housing needed in both rural and urban areas and the consideration of limitations in the availability of resources such as building materials and finance. Each state in India is currently investigating the developments in the prefabricated system and its potential to overcome the shortages of housing accommodation in this country. The Indian government, involved through its agency, the Building Materials and technology promotion council (BMTPC) and National Urban Housing and Habitat Policy (NUHHP) has been persistently pushing the construction industry to utilize the prefab method of construction since the year 2016. It is a part of an incorporated venture to further improving the aptitude, potential, efficiency and competitiveness of the industry as well as to diminish the industry's dependence on natural resources and unskilled labor. It is an attempt by the Indian construction industry to encourage positive inroads in matters related to construction-site safety concerning a working environment that is cleaner, more convenient and more organized. This paper makes an overview of the housing status in India and adoption of suitable and cost effective technologies in the country.

INTRODUCTION The Architects, engineers, contractors and planers are still unable to switch from conventional construction systems even after such a heavy and urgent demand. Its due to lack of awareness, support from authorities and distrust on the new technological advancement because of unavailability of sufficient and proper design guides and provision in IS codes and structural analysis software giants like STAAD.PRO, ETABS, Autodesk Revit, etc. Although the Building Materials & Technology Promotion Council (BMTPC), Ministry of Housing & Urban Poverty Alleviation, Government of India has taken an initiative in this direction to provide support to Architects and engineers to adopt new building technologies. BMTPC took an initiative to study/select emerging technologies suitable to Indian geo-climatic conditions. The conventional construction systems are primarily cast in-situ slow pace construction systems and cannot meet the present requirement of housing shortage. Therefore, it is call of the day to adopt new construction systems, which are fast track and at the same time meet functional and structural requirements, which includes Constituted Technology Advisory Group for identification, evaluation and selection of the suitable technologies/ systems, comprising of eminent experts from Government, CSIR, academic and private agencies. It is envisaged to construct 20 million houses by 2022 in urban area and about 10 million houses in next 3 years in rural areas (urban : 2.5 million houses a year, 7000 houses per day). Such a heavy requirement puts a very massive load on the natural resources and conventional building materials, so that brings us to consider alternative new technologies for mass housing, keeping in mind Speed, Quality, Safety, Life Cycle cost, Thermal, acoustics, Fire, etc. In addition, the need of the hour suggests use of renewable resources for building materials, use of raw materials resources based on waste products, efficient use of existing conventional materials by producing factory made (pre-cast) building components, affordability and sustainability, Industrialization of housing sector. 2. OBJECTIVE The purpose of this paper focuses on the literature review of the prefabricated system of construction methodology. The author tries to bring out the merits and demerits of prefabricated construction to its readers. For this purpose, this paper presents the five major prefabrication system approved and promoted by BMTPC
