How much coarse aggregate do you need to build a house in Fiji?
A 150 m² single-storey house in Fiji needs roughly 23 m³ of coarse aggregate — about 0.15 m³ per m² of floor area. That is computed from Fiji construction conventions, including the local wastage allowance.
Coarse aggregate (stone) quantities for a house in Fiji, computed from how buildings are actually put up here rather than from a global average. The tables below run from a small 50 m² dwelling to a 400 m² family home, and the method section shows how to reproduce every figure by hand so you can adapt it to your own plan.
Coarse aggregate (stone) by house size in Fiji
| Floor area | Coarse aggregate (stone) required | Per m² of floor |
|---|---|---|
| 50 m² | 9 m³ | 0.18 |
| 75 m² | 12 m³ | 0.16 |
| 100 m² | 16 m³ | 0.16 |
| 150 m² | 23 m³ | 0.15 |
| 200 m² | 30 m³ | 0.15 |
| 250 m² | 37 m³ | 0.15 |
| 300 m² | 44 m³ | 0.15 |
| 400 m² | 58 m³ | 0.14 |
Single-storey. The per-m² rate falls as the house grows — a small house has more wall and roof per square metre of floor than a large one, which is why these are computed size by size rather than scaled from a single rate.
What drives the quantity in Fiji
| Factor | Local value | Effect |
|---|---|---|
| General concrete mix | 1:2:4 | 4 parts stone — the bulk of every cubic metre of footing concrete. |
| Structural concrete mix | 1:1.5:3 | Richer mix, so proportionally less stone per m³ but placed in the most critical elements. |
| Hardcore filling | 150 mm | Separate from concrete aggregate, but usually the same quarry and the same delivery run. |
| Ground slab thickness | 100 mm | Slab volume drives the largest single aggregate order on a single-storey house. |
How to calculate it yourself
- 01
Total the concrete volume by element: footings, blinding, ground slab and any suspended slab.
- 02
Apply the dry factor of 1.54.
- 03
Take the stone share — 4 parts in 7 for general concrete.
- 04
Order hardcore separately: it is a different, cheaper grade and is measured as compacted thickness, not loose volume.
Buying and site notes
- —Nominal size matters: 19–20 mm stone for general work, smaller where reinforcement is congested. Oversized stone in a thin slab causes honeycombing.
- —Compacted hardcore settles roughly 20% below loose delivered volume — order for the compacted depth you need.
- —Wash or reject dusty aggregate. Fines coating the stone stop cement bonding to it.

How much coarse aggregate does a house need in Fiji?
+
A 150 m² single-storey house in Fiji needs roughly 23 m³ of coarse aggregate — about 0.15 m³ per m² of floor area. That is computed from Fiji construction conventions, including the local wastage allowance.
How much coarse aggregate per square metre in Fiji?
+
About 0.15 m³ per m² of floor area for a single-storey house. The figure is not linear across sizes — a small house has proportionally more wall and roof per m² of floor than a large one, which is why the table above is computed size by size rather than scaled from one rate.
What changes the quantity of coarse aggregate needed?
+
General concrete mix (1:2:4) — 4 parts stone — the bulk of every cubic metre of footing concrete. Structural concrete mix (1:1.5:3) — Richer mix, so proportionally less stone per m³ but placed in the most critical elements. Hardcore filling (150 mm) — Separate from concrete aggregate, but usually the same quarry and the same delivery run.
Is wastage included?
+
Where it applies, yes — a 5% allowance is carried on the perishable materials (walling units, tiles, paint). Bulk materials like sand and stone carry handling loss instead. Ordering the theoretical quantity with no allowance reliably means a second delivery at a worse price.
How accurate is this for my own house?
+
It is a planning quantity derived from a representative rectangular footprint, so it is the right order of magnitude and internally consistent — good for budgeting and for checking a supplier's list. It is not a measured takeoff of your plan. Upload your dimensioned drawings to get quantities measured off your real geometry and priced in FJD.
Are coarse aggregate prices included?
+
No, deliberately. Material prices in Fiji move week to week and vary by region, so a price printed on a static page would be wrong within a month. This page gives you the quantity — take that to two or three local suppliers and the price will be current and competitive.
