Blocks — current prices
2 blocks items with retail prices, trends, and where to buy in Lagos
| Material | Unit | Price | Δ% | Where to buy |
|---|---|---|---|---|
9-inch Block (per piece) The standard block for external walls. A 3-bedroom bungalow needs approximately 2,500-3,500 blocks. Quality varies massively — test by dropping from waist height (should NOT break). 💡 Moulding your own blocks is 15-20% cheaper but requires space and time. One bag of cement makes 35-50 nine-inch blocks depending on the mixture ratio. Better to buy machine-vibrated blocks than hand-moulded — stronger and more uniform. 📦 Per 1000: N160,000-N220,000 | per piece | ₦180–250 | +12.0% | 📍 Block industries across Lagos 📍 Order from moulders directly |
6-inch Block (per piece) Used for internal walls/partitions. Cheaper and lighter than 9-inch but NOT load-bearing — never use for external walls. 📦 Per 1000: N110,000-N160,000 | per piece | ₦120–180 | +10.0% | 📍 Block industries across Lagos |

📝 The Lagos context
Blocks are what most of a Lagos house is actually made of, and the two decisions that matter are size and quality. Sandcrete (cement-sand) blocks come mainly as 6-inch and 9-inch: 9-inch for external and load-bearing walls where strength and insulation count, 6-inch for internal partitions where you want to save space and money. Hollow blocks are the norm; solid blocks are used where extra strength is needed.
The bigger issue is how they are made. A good block has enough cement in the mix and is properly cured; a bad one is starved of cement to cut cost and crumbles under load or weather. Machine-vibrated blocks are denser and more consistent than hand-moulded ones, which is why serious builders either buy from a reputable block industry or mould on-site under supervision so they can control the cement content. A cheap block that fails is the most expensive block you can buy.
On logistics, blocks are heavy and cheap per unit, so transport is a real part of the cost — buying from a block yard close to the site, or moulding on-site, often beats a lower per-block price from far away once haulage is counted. Work out your block count from the wall area early, add a breakage allowance, and inspect a sample before a big order: a well-made block rings solid and has clean, sharp edges, while a weak one sounds dull and sheds sand when you rub it.
Because blocks are ordered in the thousands, a few naira per block and a small percentage of breakage add up fast on a real build. Convert your wall area to a block count with the bricklayer or the block yard, then add roughly five to ten percent for breakage and offcuts so you are not left a few hundred blocks short mid-wall. Order in full loads to spread the haulage, take delivery only when the site can store them without damage, and reject any batch that turns up already chipped or crumbling — a weak block is a false economy you will be living behind for decades.
