"How much cement?" is the single most asked question on a new construction site, usually followed by panic two weeks in when you've under-ordered. Here's a clean estimation guide for a 1000 sqft G+0 (ground floor only) home in Chennai, with the numbers we share with our regular contractors.
Heads up: these are working estimates, not engineering quantities. Your structural engineer's BOM is the authoritative number — always use that for actual orders.
TL;DR — quantities for a 1000 sqft single-storey home
| Material | Quantity | Approximate cost (May 2026) |
|---|---|---|
| Cement (PPC, 50kg bags) | 180–220 bags | ₹74,000–₹90,000 |
| TMT steel | 2.5–3.5 tonnes | ₹1,55,000–₹2,15,000 |
| AAC blocks (6") | 2,800–3,200 pieces | ₹1,65,000–₹1,90,000 |
| OR red bricks | 22,000–26,000 pieces | ₹1,55,000–₹1,80,000 |
| M-Sand | 35–45 tonnes | ₹50,000–₹65,000 |
| 20mm jelly (aggregate) | 25–30 tonnes | ₹33,000–₹40,000 |
| Plumbing + electrical + paint | varies | ₹2,50,000–₹4,00,000 |
| Material total | ₹7,50,000–₹10,00,000 |
These numbers assume a basic spec — not premium fittings. Premium spec can add 30–50%.
Cement: the rule of thumb
For a 1000 sqft house with a standard RCC frame:
- Slab + columns + beams (RCC work): 110–130 bags
- Brickwork mortar: 25–35 bags
- Plastering: 35–45 bags
- Flooring + finishing: 10–15 bags
- Buffer for wastage/error: 5–10 bags
Total: 180–220 PPC cement bags.
Use PPC (Pozzolana Portland Cement) for most residential work — it's slightly cheaper than OPC and gives better long-term strength. Brands we stock: UltraTech, Ramco Supergrade, Dalmia, JSW, Chettinad. All deliver to your Chennai site in 60 min — see cement options →.
Pro tip: order in batches of 50 bags, not the full 200 upfront. Cement loses strength after 90 days even in sealed bags. Site-stored bags ruined by humidity is the #1 silent cost on Chennai sites.
TMT steel: the rule of thumb
Standard residential rule: 3.5–4 kg of TMT per square foot of built-up area for a single-storey home. For G+1, it climbs to 4.5–5 kg/sqft. For G+2 and above, get an engineer's BOM — don't estimate.
For 1000 sqft G+0: 2.5–3.5 tonnes (2500–3500 kg).
Mix of diameters (typical):
- 8mm: 25% — stirrups, rings
- 10mm: 20% — slab top, distribution
- 12mm: 30% — slab main, beam top
- 16mm: 15% — beam main, columns
- 20mm: 10% — heavy beams, larger columns
Brands we stock: ARS, Isteel, Arun, Tata. Grade Fe 500D minimum, Fe 550D for any earthquake-zone build. See TMT options → or read our guide to TMT grades.
Minimum order: 500 kg per diameter for direct delivery. Smaller pickups can be combined.
Blocks vs bricks — pick one, not both
For a 1000 sqft single-storey, you need walling for roughly 2200–2500 sqft of wall area (external + internal walls combined, both sides).
If AAC blocks: 2800–3200 pieces of 6" blocks (one block covers about 0.9 sqft of wall surface). Plus 8–10 bags of AAC adhesive (Ramco Block Fix or MYK products).
If red bricks: 22000–26000 pieces standard size. Plus extra cement (30–35 bags) for the much thicker mortar joints.
AAC works out 10–15% more upfront but saves on steel, plaster and labour — see our AAC vs bricks comparison.
Sand and aggregate
The cement/sand/aggregate ratio for concrete is 1:1.5:3 (PCC) to 1:2:4 (RCC).
For a 1000 sqft house:
- M-Sand: 35–45 tonnes (around 60–70% used in plastering and mortar, rest in concrete)
- P-Sand: 8–12 tonnes (finer sand, plastering finish coat only)
- 20mm jelly stone: 25–30 tonnes (RCC structural work)
- 40mm jelly stone: 10–15 tonnes (foundation PCC, basement filling)
Order in 6-tonne tipper loads. Don't take less than 4 tonnes per trip — transport cost ruins the per-tonne economics. We deliver same-day across Chennai — WhatsApp us for a quote.
Plumbing, electrical, paint — order-of-magnitude
Less standardised because it depends on your spec, but ballpark:
- PVC pipes (Finolex/Prince/Ashirvad): ₹30,000–₹50,000 for full house plumbing
- Electrical (wires, switches, MCBs, conduits): ₹70,000–₹1,20,000 depending on quality
- Paint (primer + 2 coats interior + exterior): ₹60,000–₹1,00,000 for 2000+ sqft of wall area
- Tiles + tile adhesive + grout: ₹1,00,000–₹2,00,000 for floors + bathroom walls
Order timing — when to bring what
| Stage | Order this |
|---|---|
| Foundation | Cement, steel (8mm for stirrups), 40mm jelly, M-sand |
| Plinth + ground floor columns | More cement, 10/12/16mm steel, 20mm jelly |
| Slab | Most cement consumption (1 day's pour), full slab steel, jelly |
| Brickwork | AAC blocks or bricks, AAC adhesive, M-sand |
| Plaster | Cement, P-sand |
| Electrical/plumbing rough-in | Conduit pipes, junction boxes, PVC pipes |
| Tiling | Tile adhesive, grout, spacers |
| Painting | Primer, putty, emulsion |
| Finishing | Bathroom fittings, switches/sockets, light fixtures |
