🇮🇳 India vs 🇵🇬 Papua New Guinea · Construction cost comparison
Cost to build: India vs Papua New Guinea
Building is cheaper in India. On our construction cost index India sits at 24 against Papua New Guinea at 52 (United States = 100), so the same building costs roughly 54% less to construct there. A standard 150 m² three-bedroom house runs about $50,400–$93,600 in India and $109,200–$202,800 in Papua New Guinea.
A side-by-side comparison of what it costs to build in India and Papua New Guinea — and, more usefully, why they differ. The gap is not just labour rates: the two markets measure bills to different standards, build walls to different thicknesses, found at different depths and face different code requirements. All of that is below, computed from each country's own construction conventions.
Cost, side by side
| 🇮🇳 India | 🇵🇬 Papua New Guinea | |
|---|---|---|
| Construction cost index (US = 100) | 24 | 52 |
| Cost per m² (standard house) | $336 – $624 | $728 – $1,352 |
| 150 m² three-bedroom house | $50,400 – $93,600 | $109,200 – $202,800 |
| Local currency | INR (₹) | PGK (K) |
Order-of-magnitude benchmarks in USD for comparability, construction cost only — excluding land, professional fees and statutory charges in both markets.
Why the two markets differ
The headline gap is labour and materials. The differences below are the ones that actually change the building — and therefore change the bill for an identical drawing.
| Factor | India | Papua New Guinea |
|---|---|---|
Measurement standard Different standards. A bill measured for one market normally has to be re-measured before contractors in the other will price it competitively. | IS 1200 | SMM7 |
External wall construction Wall thickness and unit format change the masonry quantity for an identical floor plan — one of the reasons the same drawing has a different bill in each country. | 225 mm, 110/m² | 225 mm, 110/m² |
Mortar mix Richer mortar consumes more cement across the whole building — a small ratio difference is a large bill difference. | 1:5 | 1:5 |
Foundation depth Neither market is frost-governed, so depth follows bearing capacity and local convention. | 0.60 m | 0.60 m |
Seismic band Seismic detailing adds reinforcement and connection work throughout the structure — typically 5–15% on structural cost in the higher band. | moderate | high |
Wind band Higher wind bands require tie-downs and strengthened fixings, and cyclonic zones add impact-rated glazing. | normal | high |
Insulation required Same envelope expectation in both markets. | No | No |
Foul drainage Same disposal arrangement in both, so external works is comparable on this item. | Septic tank & soakaway | Septic tank & soakaway |
Roof pitch convention Pitch converts plan area into real roof surface — a steeper convention buys more covering, timber and labour for the same footprint. | 25° | 25° |
India vs Papua New Guinea — frequently asked
Is it cheaper to build in India or Papua New Guinea?
+
Building is cheaper in India. On our construction cost index India sits at 24 against Papua New Guinea at 52 (United States = 100), so the same building costs roughly 54% less to construct there. A standard 150 m² three-bedroom house runs about $50,400–$93,600 in India and $109,200–$202,800 in Papua New Guinea.
What is the cost per square metre in each?
+
About $336–$624 per m² in India and $728–$1,352 per m² in Papua New Guinea, for a standard-specification single-storey house. Rates rise with storey height and specification in both markets.
Why is there a difference at all?
+
Three things dominate: labour cost, how much of the material basket has to be imported, and what the building code requires. Here both markets have similar envelope requirements, so the gap is driven mainly by labour and materials.
Can I use the same drawings in both countries?
+
Not directly. Beyond the code differences, India measures to IS 1200 and Papua New Guinea to SMM7, so the bill has to be re-measured before local contractors will price it properly.
How do I get a real figure rather than a benchmark?
+
Upload your dimensioned floor plans and generate a measured bill of quantities for whichever market you are building in — priced in INR or PGK, in that country's own measurement standard, with every rate source-cited.
