How much bricks and blocks do you need to build a house in Nigeria?
A 150 m² single-storey house in Nigeria needs roughly 16,837 no. of bricks and blocks — about 112.2 no. per m² of floor area. That is computed from Nigeria construction conventions: 225 mm external walls at 50 units per m², including the local wastage allowance.
Bricks & blocks quantities for a house in Nigeria, 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.
Bricks & blocks by house size in Nigeria
| Floor area | Bricks & blocks required | Per m² of floor |
|---|---|---|
| 50 m² | 9,721 no. | 194.4 |
| 75 m² | 11,905 no. | 158.7 |
| 100 m² | 13,747 no. | 137.5 |
| 150 m² | 16,837 no. | 112.2 |
| 200 m² | 19,441 no. | 97.2 |
| 250 m² | 21,737 no. | 86.9 |
| 300 m² | 23,810 no. | 79.4 |
| 400 m² | 27,494 no. | 68.7 |
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.
Where it goes — 150 m² house
External walling units (bricks/blocks) 128 m² face × 50/m² × 1.05 wastage | 6,694 no. |
Internal walling units 193 m² face × 50/m² × 1.05 wastage | 10,143 no. |
What drives the quantity in Nigeria
| Factor | Local value | Effect |
|---|---|---|
| External wall thickness | 225 mm | Thickness decides whether the wall is one unit thick or two, which doubles the count for the same wall area. |
| Units per m² of external wall | 50 | The single biggest number on this page. It follows from the unit format used locally. |
| Internal partition thickness | 115 mm | At 50 units/m² — partitions are cheaper per m² but there is a lot of partition in a house. |
| Storey height | 3 m | Wall area is perimeter × height, so an extra 300 mm of ceiling height costs units on every wall in the building. |
| Wastage allowance | 5% | Breakage in transit, cutting at openings and corners. Ordering the theoretical count guarantees a second delivery. |
How to calculate it yourself
- 01
Measure the total length of external walls and multiply by the storey height to get gross wall area.
- 02
Deduct the area of every door and window opening — around 15% of external wall face on a typical house.
- 03
Multiply the net area by 50 units per m² for external walls.
- 04
Repeat for internal partitions at 50 units per m², deducting about 8% for door openings.
- 05
Add 5% for wastage, then round up to the delivery load size.
Buying and site notes
- —Order the whole structure in one batch where cash flow allows — colour and size vary noticeably between production runs and the difference shows on a fair-faced wall.
- —Stack on level, drained ground. A pallet that sinks and topples writes off a surprising share of a delivery.
- —Check a sample for size and squareness before accepting the load — undersized units mean thicker mortar joints and more cement.

How much bricks and blocks does a house need in Nigeria?
+
A 150 m² single-storey house in Nigeria needs roughly 16,837 no. of bricks and blocks — about 112.2 no. per m² of floor area. That is computed from Nigeria construction conventions: 225 mm external walls at 50 units per m², including the local wastage allowance.
How much bricks and blocks per square metre in Nigeria?
+
About 112.2 no. 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 bricks and blocks needed?
+
External wall thickness (225 mm) — Thickness decides whether the wall is one unit thick or two, which doubles the count for the same wall area. Units per m² of external wall (50) — The single biggest number on this page. It follows from the unit format used locally. Internal partition thickness (115 mm) — At 50 units/m² — partitions are cheaper per m² but there is a lot of partition in a house.
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 NGN.
Are bricks and blocks prices included?
+
No, deliberately. Material prices in Nigeria 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.
