So, you're building your dream house on a 1000 sqft plot. Amazing. But one of the first real questions that hit every builder is:
"Exactly how many bricks will I need?"
Instead of going by thumb rules or random contractor guesses, let's actually calculate the brick count based on a common 2BHK layout for a 1000 sqft house in India.
We'll walk through:
- Outer walls
- Internal partitions
- Wall thickness types
- Two common brick sizes
- Cost estimate
And yes — we’ll use the actual layout to do it. Not just averages.
What Layout Are We Using?
We're basing this estimate on a real 1000 sqft layout, common across towns in Bihar and other parts of India. It has:
- 2 Bedrooms
- 1 Living Room
- 1 Kitchen
- 2 Bathrooms
- Staircase area
- Parking space
Wall thickness:
- Outer walls – 10 inches (Full brick)
- Internal walls – 5 inches (Half brick)
Total Wall Lengths from Layout
Let’s calculate the total length of walls:
Outer Boundary (10-inch walls)
- Front: 25 ft
- Back: 25 ft
- Left: 40 ft
- Right: 40 ft
Total = 25 + 25 + 40 + 40 = 130 ft
Internal Walls (5-inch walls)
Here's a breakdown from the layout:
- Between Bedroom 1 & 2: 12'6" (12.5 ft)
- Inside Bedroom 2: 10'11" (10.9 ft)
- Living to bedroom corridor: 3 ft
- Between bathrooms: 7'1" (7.1 ft)
- Kitchen to stair: 12'7" (12.6 ft)
- Bath & stair walls combined: 2.5 ft + 5 ft + 7 ft + 7 ft
Let’s sum all:
Internal walls total ≈ 120 ft (rounded conservatively)
Brick Sizes We’re Using
| Type | Size (inches) | Volume (cu.in) |
|---|---|---|
| Standard Brick A | 10 × 5 × 3 | 150 cu.in |
| Standard Brick B | 9 × 4.5 × 3 | 121.5 cu.in |
We'll estimate for both.
Brick Estimation Without Deductions
Outer Walls (10-inch)
Wall area = 130 ft × 10 ft height = 1300 sqft
- Brick A (10×5×3): 1300 × 7 = 9100 bricks
- Brick B (9×4.5×3): 1300 × 7.5 = 9750 bricks
Internal Walls (5-inch)
Wall area = 120 ft × 10 ft height = 1200 sqft
- Brick A: 1200 × 3.5 = 4200 bricks
- Brick B: 1200 × 4 = 4800 bricks
Add 10% Wastage
| Type | Outer Bricks | Internal Bricks | Total (Before Wastage) | 10% Extra | Final Count |
|---|---|---|---|---|---|
| Brick A | 9100 | 4200 | 13,300 | 1330 | 14,630 |
| Brick B | 9750 | 4800 | 14,550 | 1455 | 16,005 |
💰 Cost Estimation (Assumed Rates)
- Brick A (10×5×3): ₹8 each
- Brick B (9×4.5×3): ₹7 each
| Type | Brick Count | Cost/Brick | Total Cost |
|---|---|---|---|
| Brick A | 14,630 | ₹8 | ₹1,17,040 |
| Brick B | 16,005 | ₹7 | ₹1,12,035 |

Optional Additions
Staircase Wall & Parapet
Assume:
- Stair wall: 10 ft × 10 ft = 100 sqft
- Parapet (2 ft × 130 ft) = 260 sqft
Total = 360 sqft
- Brick A: 360 × 7 = 2520 → 2772 with 10%
- Brick B: 360 × 7.5 = 2700 → 2970 with 10%
Optional Deductions (Windows, Doors, Ventilators)
| Type | Size (ft) | Approx Bricks |
|---|---|---|
| 6 Doors | 7' × 3' | ~750 bricks |
| 5 Windows | 4' × 3' | ~500 bricks |
| 2 Ventilators | 1.5' × 2' | ~75 bricks |
Total Deduction: ~1325 bricks
Optional: Mortar Layer Deduction
Mortar between bricks reduces total count slightly — around 3–5%.
