A 3-bedroom bungalow in Nigeria typically takes 450–650 bags of cement; a 4-bedroom duplex 1,000–1,500 bags; and a 5-bedroom duplex 1,300–1,900 bags across the whole build. Cement isn’t just for blocks — it goes into the foundation, columns, decking, plastering and screeding too. At mid-2026 prices of roughly ₦9,500–₦13,000 a bag, cement alone runs from about ₦4.5M on a bungalow to ₦20M+ on a large duplex. Your exact figure comes from a bill of quantities, but these give you a solid planning number. (Current as of July 2026.)
Cement is the single most-used material in any Nigerian build, and its price swings more than almost anything else — so knowing roughly how many bags your house needs is half of keeping a budget under control. Here’s the honest breakdown by building type, where all that cement actually goes, and what it costs in 2026.
How many bags of cement does a house need?
It depends on the size and whether it’s a bungalow or a duplex (two floors roughly double the concrete work). Here’s the planning range by common build type.
| Building type | Approx. cement (bags) | At ₦11,000/bag |
|---|---|---|
| 2-bedroom flat | 350–500 | ₦3.9M–₦5.5M |
| 3-bedroom bungalow | 450–650 | ₦5.0M–₦7.2M |
| 3-bedroom flat | 500–750 | ₦5.5M–₦8.3M |
| 4-bedroom duplex | 1,000–1,500 | ₦11.0M–₦16.5M |
| 5-bedroom duplex | 1,300–1,900 | ₦14.3M–₦20.9M |
Where all the cement actually goes
People assume cement is mostly for laying blocks. It’s not — the blockwork is often the smaller share. Across a full build, cement is consumed in the foundation and floor slab, moulding and setting blocks, columns, beams and lintels, the decking (a big one on duplexes), and finally plastering and screeding. That’s why a duplex’s cement bill dwarfs a bungalow’s: two suspended floors and more structural concrete.
Worth knowing: The exact number comes from your bill of quantities (BOQ), calculated from your drawings. Concrete mix ratios (1:2:4 for structure, weaker mixes for blocks), wall area and slab thickness all move it. Treat the ranges here as budgeting figures, not an order sheet.
What cement costs in 2026 — and why it moves
In mid-2026, a 50kg bag commonly runs about ₦9,500–₦13,000 depending on brand (Dangote, BUA, Lafarge), location and whether you buy by the bag or by the trailer-load. Buying a full trailer directly from a depot is far cheaper per bag than retail. Because cement tracks energy and FX costs, the price can jump within a single build — which is exactly why you should confirm the current rate before ordering. We keep the live figure in our Construction Cost Tracker, and the major producers (like Dangote Cement) publish depot pricing.
Watch out: Don’t buy all your cement at once “to beat price increases” unless you can store it properly — cement absorbs moisture and goes hard in weeks in Nigeria’s humidity. Buy in stages tied to your build phases, and keep it dry and off the ground.

Frequently asked questions
How many bags of cement to build a 3-bedroom bungalow in Nigeria?
Roughly 450–650 bags across foundation, blockwork, columns, plastering and screeding. Your exact figure comes from a bill of quantities based on your drawings.
How many bags of cement for a duplex?
About 1,000–1,500 bags for a 4-bedroom duplex and 1,300–1,900 for a 5-bedroom, because two floors add significant structural concrete and decking.
How much does cement cost in Nigeria in 2026?
Around ₦9,500–₦13,000 per 50kg bag depending on brand, location and order size. Buying by the trailer from a depot is cheaper per bag than retail.
Should I stockpile cement to beat price rises?
Only if you can store it dry — cement hardens within weeks in humid conditions. Buy in phases tied to your build stages rather than all at once.
