Quick Answer:
How do you compare house construction quotes? Never compare just the final price or the per-square-foot rate. To compare quotes accurately, demand a detailed Bill of Quantities (BOQ) from each builder. Compare the specific brands of cement, steel, and wires they promise. Check the price allowances for tiles (e.g., ₹60/sq.ft vs ₹100/sq.ft). Finally, verify how they calculate the built-up area and check for hidden costs like compound walls and temporary electricity.
You have decided to build your dream home and have reached out to three different contractors. A few days later, you receive the quotes:
- Contractor A: ₹1,700 per sq.ft
- Contractor B: ₹2,100 per sq.ft
- Contractor C: ₹2,400 per sq.ft
It is incredibly tempting to immediately hire Contractor A to save ₹400 per sq.ft. However, in the construction industry, the lowest quote is frequently the most dangerous one.
As a premium builder offering transparent construction packages, we often see homeowners tricked by "fake low" estimates. In this guide, we will teach you how to read a construction quote like an expert and ensure you are comparing apples to apples.

1. The BOQ is King (Brand and Grade Matter)
If a quote simply says "TMT Steel and Cement provided," throw it in the trash. You need a detailed Bill of Quantities (BOQ) or a comprehensive Specification Sheet to know exactly what you are paying for.
When comparing quotes, check the specific brands and grades:
- Steel: Are they using premium Fe500D steel from Tata/JSW, or a local, unbranded secondary steel that is ₹15,000 cheaper per ton?
- Cement: Are they using Grade 53 OPC cement (Ultratech/ACC) for structural work, or cheaper PPC cement everywhere?
- Wires: Are they using fire-retardant copper wires from Finolex/Polycab, or a cheap local brand that poses a fire hazard?
Contractor A (the cheapest) is almost certainly planning to use inferior, local brands to maintain their profit margin.
2. Watch Out for "Price Allowances"
When quoting for finishes like tiles or bathroom fixtures, contractors use "allowances." This means they allocate a specific budget for those items. If you choose something more expensive, you pay the difference.
This is where cheap contractors hide the real cost of your home. For example:
| Item | Contractor A's Allowance (Cheap) | Contractor B's Allowance (Realistic) |
|---|---|---|
| Flooring Tiles | ₹45 / sq.ft | ₹90 / sq.ft |
| Bathroom Wall Tiles | ₹30 / sq.ft | ₹60 / sq.ft |
| Main Door | ₹15,000 allowance | ₹35,000 allowance (Genuine Teak) |
If you go with Contractor A, you will quickly realize that ₹45/sq.ft buys very ugly, low-quality tiles. You will inevitably upgrade to the ₹90 tile anyway, and Contractor A will bill you for the massive "extra" cost at the end of the project.
3. How is the Built-Up Area Calculated?
This is the most common scam in the industry. Your total cost is calculated as: Built-Up Area x Per Sq.Ft Rate.
If a contractor quotes a very low per-square-foot rate, they often inflate the built-up area to compensate. They might charge you 100% of the slab rate for an open terrace, or measure the area from the outer edge of the sunshades (chajjas) instead of the walls.
The Fix: Ask every contractor to provide a detailed floor plan clearly highlighting the exact boundaries they used to calculate the total square footage.
4. What is Explicitly Excluded?
When evaluating what is included in turnkey construction, it is equally important to know what is excluded.
Contractor A's quote might look cheap because it completely excludes the compound wall, the borewell, temporary electricity charges, and waterproofing. Contractor B's quote is higher because it transparently includes all these necessities.
5. Compare the Payment Terms
Never sign a contract that demands 40% of the money upfront before a single brick is laid. Good builders tie their payments to construction milestones.
A fair schedule looks like this:
- 10% - Booking & Design Phase
- 15% - Upon completion of Foundation
- 15% - Upon completion of Ground Floor Roof Slab
- 15% - Upon completion of First Floor Roof Slab
- ...and so on, retaining the final 5% until the keys are handed over.
