Decent housing is one of the basic needs of human beings. Presently, millions of people do not have a suitable roof over their heads. The entire ecosystem now a days needs such type of materials that will be helpful in reducing the cost of the building unit without any change in its properties than conventional building has. Low Cost-housing materials is a comparative term that has a lot to do about financing that helps to reduce construction costs by using various new techniques like effective management, appropriate use of local resources, skills, and technology, without sacrificing quality or structural life. In this review, a comparison was carried between conventional building materials and various alternative low-cost housing materials like bamboo, precast concrete, cow dung, straw dust etc. that are being used in construction industry without scarifying the integration of the structure. The objective of this research is to highlight and investigate various types of ecofriendly materials and their extraction techniques that can be used to create low-cost structures that can withstand extreme conditions. An attempt is made by me to highlight and point out various low-cost housing materials to be used in ecofriendly environment thereby enabling to maintain the cost and the structural durability.
