Construction cost per sq ft depends on your city, the specification and who builds it. A number from another city, or from last year, can be off by 30% or more. The reliable way is to estimate the main materials for your house and price them at your own local rates.
What a per-sq-ft quote usually includes
When a contractor gives you a rate per sq ft, ask what it covers. A typical construction quote includes:
- Foundation, RCC frame (columns, beams, slabs) and walls
- Plaster, flooring, wall tiles in bathrooms and kitchen
- Doors, windows, basic electrical and plumbing
- Painting
It usually does not include land, approvals and architect fees, boundary wall, borewell, sump and overhead tank, modular kitchen and wardrobes, or interiors. These can add a lot to the final bill.
Also check which area the rate is on. Built-up area (including walls) and carpet area (floor inside the walls) differ by 10–20%.
Material thumb rules for an RCC-frame house
These are common site thumb rules for a ground or G+1 house with RCC frame and brick walls, per sq ft of built-up area. Use them for a first estimate. Your engineer's quantities will be more accurate.
| Material | Per sq ft of built-up area | For 1,000 sq ft |
|---|---|---|
| Cement | 0.4 bags | 400 bags |
| Steel | 3.5–4.5 kg | 3.5–4.5 tonnes |
| Sand | 1.8 cft | 1,800 cft |
| Aggregate | 1.35 cft | 1,350 cft |
| Bricks | 8–10 | 8,000–10,000 |
Work out your own cost: example
The rates below are example figures only. Replace each one with the rate you get from your local dealer today.
| Item | Quantity (1,000 sq ft) | Example rate | Amount |
|---|---|---|---|
| Cement | 400 bags | ₹380 / bag | ₹1,52,000 |
| Steel | 4,000 kg | ₹65 / kg | ₹2,60,000 |
| Sand | 1,800 cft | ₹60 / cft | ₹1,08,000 |
| Aggregate | 1,350 cft | ₹50 / cft | ₹67,500 |
| Bricks | 9,000 | ₹8 / brick | ₹72,000 |
| Core structure materials | ₹6,59,500 |
Core structure materials are usually less than half of the total cost. Add labour, flooring and tiles, doors and windows, electrical, plumbing and sanitaryware, and painting. Finishing items vary most with your choices. Basic tiles and fittings versus premium ones can change the total by 30–50%.
What changes your cost the most
- Soil and foundation. Weak or black cotton soil needs deeper or larger foundations.
- Number of floors. Foundations and roof are shared, so a G+1 costs less per sq ft than a single floor of the same total area.
- Finishing specification. Flooring, bathroom fittings, windows and doors.
- Labour model. A full contract with materials, a labour-only contract with you buying materials, or a builder's package.
- Access to the site. Narrow lanes and long distances raise transport and handling costs.
Ways to keep costs down without cutting strength
- Get the structural drawing from a qualified engineer and follow it. Over-design wastes steel, and under-design costs much more later.
- Buy cement and steel in bulk at the right stage, from dealers with proper bills.
- Use a simple, rectangular plan. Every extra corner adds formwork, steel and labour.
- Decide finishes before work starts. Changes mid-way are the biggest source of overruns.
