Ask five bricklayers “how many blocks for a 3-bedroom bungalow?” and you’ll get five answers. That’s not because anyone is lying — it’s because the honest answer is a range, and the range moves with your floor plan. Below we give you the working numbers builders actually use in 2026, show where each bag and block goes, and flag the costs most quantity lists quietly skip.

These figures assume a typical 3-bedroom bungalow of about 150–200 sqm sitting on a 450–600 sqm plot, built with sandcrete blocks. If you want the full labour-and-materials picture, pair this with our cost of building a 3-bedroom bungalow guide.

How many blocks for a 3-bedroom bungalow?

For a standard 3-bedroom bungalow, budget for about 2,600–3,200 nine-inch blocks. Bungalows with longer walls, higher ceilings or a boys’ quarters push toward — and past — the top of that range. Here’s roughly where they go.

One money-saver most people miss: use 9-inch blocks only for load-bearing external walls, and 6-inch blocks for internal partitions that carry no weight. Six-inch blocks are cheaper per unit and lighter to lay, and on a full bungalow the saving runs into six figures.

How many bags of cement for a 3-bedroom bungalow?

A complete 3-bedroom bungalow typically swallows 250–450 bags of cement across every stage. Plastering is the biggest single eater — often more than the blockwork itself. Here’s the breakdown builders work to.

What will the blocks and cement actually cost in 2026?

Material prices in Nigeria move monthly, so treat these as an August 2026 snapshot, not a fixed quote. Cement in particular has climbed hard this year — a 50kg bag that sold nearer ₦8,000 in early 2026 is now widely ₦12,000–₦15,000 depending on brand and location.

So blocks and cement together land somewhere around ₦4.6m–₦9.6m (~$3,170–$6,620) for a standard bungalow — before sand, granite, iron rods, water, roofing or labour. On most 3-bedroom builds, cement and blocks are 20–30% of the total shell cost. For the full material market, see our Nigerian Construction Cost Tracker.

What most block-and-cement estimates leave out

The single number you see on other sites hides four things that quietly blow budgets:

Mould-versus-buy is not the same cost. If you cast blocks on site, 3,000 blocks need roughly 60–90 bags of cement just for moulding — on top of your mortar and plaster cement. That casting cement is often left out of “how many bags” lists entirely. Buying ready-made blocks at ₦600–₦900 each avoids that but shifts the cost to the block price.

Waste and breakage are real. Budget 5–10% extra blocks. Blocks crack in transit, corners get cut, and a bricklayer will never send back the last 40 “spare” blocks.

Block quality changes everything. A ₦600 block with too much sand and too little cement will fail your walls. Cheap blocks are the most expensive mistake in Nigerian building. Test-drop a sample before you buy a trailer-load.

Plaster eats more cement than people expect. Two coats over every internal and external wall is why plastering often outweighs the blockwork. If your walls are rough, you’ll use even more.

Frequently asked questions

How many blocks make one bag of cement?
For moulding, one 50kg bag makes about 35–50 nine-inch blocks with a decent vibrated mix. For laying, one bag bonds roughly 50 blocks in mortar. Poorer mixes stretch further but give weaker blocks.

Is it cheaper to mould blocks or buy them in 2026?
With cement at ₦12,000–₦15,000 a bag, moulding on site can save 10–20% versus buying at ₦600–₦900 each — but only if you control quality and have space and water. Many self-builders buy ready-made to avoid weak blocks and theft of materials.

How many bags of cement for the foundation alone?
For a standard 3-bedroom bungalow, expect about 90–140 bags for the foundation, footings and oversite (german) floor combined. Deeper trenches on soft or waterlogged soil push this higher.

Does a bungalow use fewer materials than a duplex?
Yes — significantly. A 5-bedroom duplex needs framed columns, beams and a suspended floor slab, so it uses far more cement and iron. See our 5-bedroom duplex cost guide for the contrast.

Why do cement prices vary so much across Nigeria?
Distance from the plant, fuel and transport costs, and local demand. Lagos, Abuja, Port Harcourt and the South-East often sit at the top of the range; states near cement plants pay less. Buy full trailer-loads direct where you can.

Methodology & sources

Block and cement quantities are standard quantity-surveying rules of thumb for a 150–200 sqm bungalow, cross-checked against Nigerian construction estimators. Prices are an August 2026 market snapshot: cement from July–August 2026 dealer reports (The Guardian, Legit.ng) and block prices from 2026 building-material listings. USD conversions use ₦1,450/$ — roughly the parallel-market rate in early August 2026 (CBN official rate ~₦1,366). Your project’s exact figures come only from a quantity take-off on your building plan. Last updated: August 2026. Next review: November 2026.
