Housing with low-cost materials and techniques for a sustainable construction in India-A review

Abstract Housing is not only a social well-being metric; it still plays a very significant role in influencing the Indian economy. Both existing or emerging this is imperative for every nation to make their rural areas a major concern priority. State stability rests in the reality that its rural and urban areas are well built to meet the desires of the people residing there. Around 27 million housing units in India alone have been traced to be in short supply. The economically poorer parts and the middle class are the bulk of the population which needs accommodation. The nation is in desperate need of patching up the huge community. Unless we struggle to cope inside this community of accommodation and food, the deficit will inevitably escalate to 38 million units by 2030. In the present sense, one drastic shift is the need for an hour. Low cost housing is housing for those who are deemed accessible by a recognized housing affordability index to those with an average household income or below as classified by the government. Low cost housing is a new concept dealing with effective budgeting and follow-up of techniques that help to reduce construction costs by using local skills and technology without sacrificing the strength performance and structural life. The usage of local resources lowers shipping expenses, the proportion of which to the cost of construction resources is large for long distances and therefore ideal for local climate. The present study deals with the extensive data collection of various materials and techniques available for low-cost housing, and the development of a strategic action plan to implement the same in India's identified places. The research further discusses the role of prefabricated concreting processes, along with 3D concrete printers and their use in low cost housing.
