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.

S. No. Item of work Percentage of
total work
For a 1000 sq ft house
1 Excavation in ordinary soil and concrete 3% Rs.21,000
2 Foundation    
3 Stonework upto plinth 5% Rs. 35000
4 Superstructure in brickwork 25% Rs. 1,75,000
5 Roofing including waterproofing 20% Rs. 1,40,000
6 Flooring 6% Rs. 42000
7 Wood work i.e. Joinery, doors and windows 15% Rs. 10.5000
8 Internal finishes 6% Rs. 42000
9 External finishes 3% Rs.21000
10 Water supply 4% Rs. 28000
11 Sanitary work 8% Rs. 56000
12 Electrification 5% Rs. 35000
13 Total 100% Rs.7Lakh


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.

S.No. Requirement of Materia Unit of measurement Quantity Approx Qyt fori000sq ft
1 Cement Bags/sqft 0.4 400 bags
2 Sand (cu ft) Cut/sqft 1.81 1800
3 Jelly (cu ft) Cut/sqft 1.14 1150
4 Bricks Nos/Sqft 34 34,000
