Housing, next to food and clothing is the most important need of a human being. The house reflects his/her socio-economic status in society. For most families, housing is perhaps a major goal of family saving effort. So it must be durable, as it is an outcome of a long drawn process of savings and aspirations.
Housing is a bundle of goods and services. It is not the product of uni-sectoral efforts. Housing production includes a multitude of tasks like land acquisition, development, laying infrastructure, site planning and architectural design on pre-conceived concepts of affordable densities, to provide for shelter, social and physical infrastructure, project finance and finally construction and delivery of the same.
It is within this context that a need was felt to look at ways of optimizing shelter cost. The usual practice involved in this area till the recent past has been to:
- Reduce area of the house to the minimum possible level
- Reduce the finishing specification of flooring, external and internal walls, fittings etc.
In last two to three decades, cost effective appropriate technologies have cross the borders of laboratory and research organizations and have reached real construction sites. Many experimental and demonstrative projects have been constructed across the country proving the strength and feasibility of these technologies.
A number of cost effective appropriate materials and technologies have been developed, standardized and are being used in the field with success over the years. Many of them have even proved themselves in the test of time. BIS has also included many of these technologies under their umbrella and are working towards covering the remaining so that minimum standardization is achieved and a standard specification for the same is evolved.
Some of the Cost effective appropriate Technologies are described in the table below
