More- over, different toxic substances such as carbon monoxide, sulfur oxides, nitrogen oxides and suspended particulate matter are invariably emitted in the atmosphere during manufacturing processes of traditional construction materials. The continuous exploitation and depletion of natural resources is harming the environment. However, with the traditional building technologies it is impossible to solve this menace as we cannot solely depend on the traditional construction materials such as concrete, bricks, wood to cover all housing needs, as they are produced from the natural resources. To reduce this dependence on conventional building material there is a need to review alternate building materials and formulate guidelines for their application in construction industry. This would result in an enormous demand of building materials like steel, cement and wood etc. If officials fail to provide accommodation for all, it is estimated that 200 million Indian will be residing in slums by 2020 (UN Habitat estimates).

The mission seeks to build 20 million housing units for the poor and make Indian cities slum free by the slum rehabilitation projects and affordable housing projects for Economically Weaker Section. In this context, the Pradhan Mantri Awas Yojana (Prime Minister Housing for All Mission, 2015), envisages to provide housing to all by 15th August 2022. With an annual population growth rate of 1.64% as compared to world population growth rate of 1.23% during the last decade there would be a great demand to fulfill housing needs in coming years.
But contrary to this, in India type and number of homes available is not adequate as per the estimation reported by the Ministry of Housing and Urban Poverty Alleviation, Government of India. This is one important component of one's life. To stay healthy one need a proper place to reside for the entire life and that is home. In addition the building up of cooperative to supply those alternative raw materials rather than importing from somewhere else would help in reducing the cost by 20–30%. After realizing the true potential of these waste materials as building material in construction industry the cost can be minimized to a greater extent. With the time more studies are going to identify the reuse of waste material like fly ash, rice husk, etc as building material. It was observed that with if the filler slab can be used as an alternative to conventional slab the cost of construction can reduce upto 25%. In order to come up with viable solutions this paper compares the construction cost for the traditional and low cost housing technologies and it was observed that with the use of technology and reuse of waste material as building material the cost of construction can be minimized to an extent.
Therefore, it has now became a necessity to adopt cost effective, innovative and environment-friendly housing technologies for the construction of houses and buildings and availing them at low cost comparatively.
To own a house by middle and lower income groups in today's economic trends is very difficult.
This paper also aims to cover the use of local materials in the different components of building to make them as low cost available solutions for low income groups. In a building the walls, floors and roofs are the most important sections, which can be analyzed distinctively based on the needs, thus, improving the speed of construction and reducing the construction cost. This paper aims to point out the various aspects of predestined building methodologies by highlighting the different available techniques, and the economical advantages achieved by its adoption. This depends on three key parameters-income level, size of dwelling unit and affordability. Low cost housing refers to those housing units which are affordable by that section of society whose income is below than median household income.
