"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
