How Many Bricks, Cement and Steel for a 1,000 sq ft House?
Whole-house thumb rules for cement, steel, sand and aggregate, and a wall-by-wall brick count for a typical 2BHK.

Building a 1,000 sq ft house and wondering how much cement, steel, sand and how many bricks to budget for? Contractors use quick thumb rules per square foot. They're useful for a first budget, but bricks in particular depend on your wall layout. Here are both: the whole-house thumb rules, and a wall-by-wall brick count you can redo for your own plan.
Whole-house estimate for 1,000 sq ft
| Material | Per sq ft (built-up) | For 1,000 sq ft |
|---|---|---|
| Cement | 0.4–0.5 bags | 400–500 bags |
| Steel (TMT bars) | 3–4.5 kg | 3,000–4,500 kg |
| Coarse aggregate | 1–1.5 cft | 1,000–1,500 cft |
| Sand | 0.8–2 cft | 800–2,000 cft |
Sand estimates vary the most between sources, because they depend on how much plastering, flooring and brickwork your design has. Always add 5–8% for wastage.
How many bricks? Count the walls
Bricks depend on wall length, not floor area. Two houses of 1,000 sq ft can need very different numbers depending on how many rooms and partitions they have. So count wall by wall. Here's a typical single-storey 2BHK of about 32 × 32 ft, with 10 ft walls and traditional bricks (230 × 110 × 75 mm) in 1:6 mortar:
| Walls | Wall area | Bricks | Cement bags | Sand |
|---|---|---|---|---|
| Outer, 9 inch (128 ft) | 1,118 sq ft | 10,690 | 26 | 184 cft |
| Inner, 4.5 inch (90 ft) | 795 sq ft | 3,800 | 7 | 51 cft |
| Total | 14,490 | 33 | 234 cft |
So this plan needs about 14,500 bricks. Before breakage, a 9-inch wall takes about 9.1 bricks per sq ft of wall face, and a 4.5-inch wall about 4.6. Using larger modular bricks (190 × 90 × 90 mm) or AAC blocks cuts the count and the mortar.

Materials for Your Wall
The rest of the building
- Concrete for footings, columns, beams and the slab: use the concrete calculator with each member's size. A typical 5-inch (125 mm) slab over 1,000 sq ft is about 11.6 m³ of concrete.
- Steel: the steel weight calculator converts bar lengths to kg (D² ÷ 162 kg per metre).
- Plaster for walls and ceilings: the plaster calculator gives cement and sand by area and thickness.
- Sand by the truckload: the sand calculator converts cft, m³ and brass.
- Paint at the end: the paint calculator.
These are planning figures. For ordering, get a bill of quantities (BOQ) from your engineer or contractor, based on your structural drawings and soil conditions.
Frequently asked questions
How many cement bags for a 1,000 sq ft house?
About 400–500 bags of 50 kg for an RCC-framed single-storey house, covering foundation, structure, brickwork, plaster and flooring. Multi-storey houses need more per sq ft.
How many bricks are needed for 1,000 sq ft?
It depends on wall length and thickness. A typical single-storey 2BHK of 1,000 sq ft with 9-inch outer and 4.5-inch inner walls needs about 14,500 traditional bricks. Count your own walls with the brick calculator.
How much steel is required for 1,000 sq ft?
Roughly 3,000–4,500 kg, or 3 to 4.5 kg per sq ft of built-up area, depending on spans, floors and the structural design.
Are these figures accurate enough to order materials?
No, they're for budgeting. Order from a bill of quantities prepared by your engineer, which follows your actual drawings.
