Food and shelter are the basic requirements to sustain life. As such, shortages of dwelling houses are becoming a major focus for government. The total shortage of dwelling units in India is estimated to nearly 4.5 crore. Housing experts say the Government of India's dream – Housing for all - could be a dominant platform to introduce low-cost technology in a big way. Perhaps, only then “housing for all” will get the priority as it has been accorded.
Low Cost Housing is a new concept which deals with effective budgeting and following of techniques which help in reducing the cost of construction by using locally available materials along with improved skills and technology without sacrificing the strength, performance and life of the structure.
Building Cost
The building construction cost can be divided into two parts namely:
Building material cost : 65 to 70 %
Labour cost : 65 to 70 %
Now in low cost housing, building material cost is less because we make use of the locally available materials and also the labour cost can be reduced by properly making the time schedule of our work. Cost of reduction is achieved by selection of more efficient material or by an improved design.
Areas from where cost can be reduced are:-
1) Reduce plinth area by using thinner wall concept; even15 cms thick solid concrete block wall.
2) Use locally available material in an innovative form like concrete blocks in place of burnt brick which consumes less energy like concrete block in place of burnt clay brick.
3) Use environment friendly materials which are substitute for conventional building components like use Precast R.C.C. Door and window frames in place of wooden frames.
4) Pre-plan every component of a house and rationalize the design procedure for reducing the size of the component in the building.
5) By planning each and every component of a house the wastage of materials due to
