Introduction
Bricks required for 1BHK house is one of the most important calculations in house construction. Before starting building work, every house owner and civil engineer wants to know how many bricks are required. Proper brick calculation helps in cost estimation, material planning, and avoiding shortage during construction.
Bricks are the main material used for wall construction. If brick quantity is not calculated correctly, construction cost may increase and work may be delayed. In this guide, you will learn how to calculate bricks required for 1BHK house with simple methods and examples.

Average Size of 1BHK House
A standard 1BHK house usually has:
- 1 bedroom
- 1 hall
- 1 kitchen
- 1 bathroom
Average size of 1BHK house = 400 to 600 sq ft
For calculation, let us consider a 500 sq ft 1BHK house.
Standard Brick Size in India
Standard brick size (with mortar):
- Length = 20 cm
- Width = 10 cm
- Height = 10 cm
Number of bricks in 1 cubic meter brickwork = 500 bricks
This is the standard value used in civil engineering.
Step-by-Step Brick Calculation for 1BHK House
Step 1: Calculate Wall Area
Assume:
Total wall length = 80 ft
Wall height = 10 ft
Wall area = 80 × 10
Wall area = 800 sq ft
Step 2: Convert into cubic meter
Wall thickness = 9 inch = 0.75 ft
Volume = Area × thickness
Volume = 800 × 0.75 = 600 cubic ft
Convert into cubic meter:
1 cubic meter = 35.3 cubic ft
Volume = 600 / 35.3
Volume = 17 m³ approx
Step 3: Number of Bricks
Bricks per m³ = 500
Total bricks = 17 × 500
Total bricks = 8500 bricks
Step 4: Add Wastage
Add 5% extra:
8500 × 5% = 425 bricks
Total bricks required =
8500 + 425 = 8925 bricks
So, bricks required for 1BHK house ≈ 9000 bricks
Bricks Required Based on House Size
| House Size | Bricks Required |
|---|---|
| 400 sq ft | 7000–8000 |
| 500 sq ft | 8500–9000 |
| 600 sq ft | 10000–11000 |
| 1000 sq ft | 16000–18000 |
This is approximate calculation.
Cost of Bricks for 1BHK House
Average brick price = ₹8 per brick
9000 bricks × ₹8 = ₹72,000
So brick cost for 1BHK house ≈ ₹70K–₹80K
Price may vary by location.
Cement and Sand for Brickwork
For 1m³ brickwork:
- Cement = 1.5 bags
- Sand = 0.3 m³
For 17m³ brickwork:
- Cement = 25 bags approx
- Sand = 5 m³ approx
This is used for mortar.
Factors Affecting Brick Quantity
Bricks required for 1BHK house depends on:
- Wall thickness
- House design
- Number of rooms
- Wall height
- Openings (doors & windows)
More walls = more bricks.
Tips to Reduce Brick Cost
- Use fly ash bricks
- Buy bricks in bulk
- Avoid brick wastage
- Use proper mortar ratio
- Hire skilled mason
Proper planning saves money.
Importance of Brick Calculation
Knowing bricks required for 1BHK house helps in:
- Accurate estimation
- Cost planning
- Material management
- Avoiding shortage
- Smooth construction
Every civil engineer must know this calculation.
Bricks calculation for a 1BHK house is an important step in planning construction materials and estimating project cost accurately. Knowing the exact number of bricks required helps avoid wastage and ensures smooth construction work. The total bricks required mainly depend on wall thickness, plinth area, ceiling height, and type of brick used.
Generally, standard modular bricks are used in most residential buildings, making calculation easier. Proper brick estimation also helps in managing labor, cement, and sand requirements efficiently. For a typical 1BHK house, preparing a detailed material estimation before starting construction can save both time and money while ensuring quality work and structural strength throughout the building process.
Conclusion
Bricks required for 1BHK house is approximately 8000 to 10000 bricks depending on house size and wall thickness. For a 500 sq ft 1BHK house, around 9000 bricks are required. Proper brick calculation helps in budgeting and smooth construction work.
Understanding brick quantity estimation is essential for civil engineers and house owners. Always add extra bricks for wastage and use quality materials for strong and durable construction.
