Cost Estimation for Home Construction
At UltraTech Building Solutions, we have developed a special "Budget Estimation Software" which gives the approximate budget needed for the constructing the house.
General Guidelines:
It is a good strategy to know beforehand the requirement of space, probable cost and approximate quantities of critical materials. As a rule, the ratio of materials to labour to overheads is 60:30:10. The current cost of construction is Rs 600-900 per sq ft depending upon finishing items.
Stages and rough percentage of total work
To give you an idea of the cost pattern for different stages, the cost is worked out for a 1000 sq ft house @ Rs 700/- per sq ft.

Yardsticks for some construction materials
Following table would give an idea of the quantities of important materials required. If their consumption is controlled, pilferage and wastage minimized, saving upto 5% to 8% could be achieved. The quantity required has been worked out for a house of 1000 sq ft.
