The Definitive Guide to Building in Nigeria in 2026: What to Expect at Every Stage
Most builders in Nigeria start with a budget and a plan.
Most run out of both before the roof goes on.
This guide is here so you don’t.
Building in Nigeria is big. It’s also messy.
Land. Law. Engineers. Contractors. Suppliers. Rain. Regulators. Neighbours.
And time, more than you plan for.
This isn’t a checklist. You’ll find those everywhere.
This is for builders who want to understand what they’re actually getting into, stage by stage, mistake by mistake, so your project finishes on time and on budget.
Before you buy land: The 3 things you can’t afford to miss
The biggest failures in Nigerian construction aren’t building failures. They’re land failures. And most people only find out after they’ve paid.
- Can the seller’s papers survive a land registry search?
C of O is strongest. Governor’s Consent and Deed of Assignment work, if registered correctly.
What kills projects: family land with no survey, excised land sold twice, “Omo-Onile” receipts with no title. Court orders don’t care that your house is finished. If the paper fails, the building comes down.
- What does the soil say?
Get a geotech report. It tells your structural engineer if you need strip, raft, or piles.
In parts of Lagos, strip foundations sink. Raft or piled foundations cost 2-3 times more, but they’re not optional. They’re physics. A geotech report is ₦200k. Fixing a failed foundation is millions.
Don’t let your contractor guess.
- What can you legally build?
Every plot has zoning rules: height, setbacks, coverage.
Designing a 4-floor block on land zoned for 2 means LASPPPA rejects your drawings. You pay your architect twice. Check with town planning first. A 30-minute call saves 3 months.
Stage 1 – Pre-construction: Paper before shovel
People rush this part. Don’t. This is where you stop problems before they start.
Survey plan
Licensed surveyor confirms your boundaries. Old surveys lie. Don’t design without a current one.
Drawings
Architect does floor plans + elevations. Structural engineer does foundation, columns, beams.
Only ARCON architects and COREN engineers can stamp drawings for permit. Using unregistered “engineers” isn’t just illegal. It’s why buildings collapse.
Building permit
LASPPPA in Lagos. FCDA in Abuja. Your state has one too. In 2026, they’re issuing Stop Work Orders and demolishing finished buildings without permits. You need: stamped drawings, survey plan, proof of title. Lagos takes 6-12 weeks. Budget for it.
Skipping the permit costs more than getting it ever will.
Bill of Quantities (BoQ)
Your QS lists every bag of cement, every rod, every day of labor, and what it should cost.
No BoQ = no budget. You’ll overspend without knowing where it went.
Contractors price against this. You manage against this.
Stage 2 – Substructure: The part you won’t see, but can’t ignore
This is everything below ground floor. Mess it up and the building fails. Slowly, then all at once.
Setting out + Excavation
Transfer the plan to the ground with pegs and lines. Mistakes here multiply.
Excavation depth comes from your soil report, not your contractor’s opinion. In waterlogged Lekki, going shallow to “save cost” means your house sinks. Depth = load-bearing capacity.
Foundation types – your soil decides
- Strip: Stable soil, 1-2 floors. Cheapest.
- Pad: Column-based structures.
- Raft: Weak/waterlogged soil. Common in coastal Lagos. 2-3x strip cost.
- Piled: Worst soil. Most expensive.
If your engineer specs raft and your contractor says “strip will do,” get a second opinion. This isn’t negotiable.
Stage 3 – Superstructure: Where structure becomes building
Columns, beams, floors, roof. This is where shortcuts kill.
Columns + Blocks
Columns carry the load. Walls just fill space.
Column size and steel spec come from your engineer. Smaller columns or fewer rods = weaker building.
Blocks vary in quality. If it crumbles in your hand, don’t use it.
Slabs + Roof
Slab strength = concrete grade + water ratio + curing time. Too much water for “workability” makes weak concrete.
Roof: Steel trusses now beat timber. No rot. No fire. No warping. Design for Nigerian rain, wide overhangs, big gutters.
Stage 4 – M&E: Do it before you plaster
Pipes, wires, AC ducts – all go in before walls are finished.
No coordination = breaking walls later to run a pipe. Get your plumber, electrician, and AC guy on site together. Plan once.
Stage 5 – Finishing: Where budgets die
Plastering. Tiles. Doors. Windows. Paint.
This stage takes longest and costs most – 30-40% of total budget.
Budget 20% and you’ll cut quality or borrow to finish.
Quick rules:
- Vitrified tiles beat ceramic in Nigeria. Easy to clean, durable.
- Aluminium windows beat wood. No humidity damage.
- Good paint isn’t expensive. Cheap paint looks bad in 6 months.
Stage 6 – External works: Don’t treat it as an afterthought
Fence. Gate. Drainage. Driveway.
Bad drainage floods your house and your neighbour’s. Get a pro to check invert levels.
No Certificate of Completion? You’ll have problems with C of O upgrades and legal disputes later.
The 5 mistakes that wreck Nigerian projects
- No BoQ – You can’t manage what you can’t measure.
- Paying mobilisation without milestones – Pay for work done, not promised.
- Buying materials last-minute – Cement moved 40% in 6 months. Buy early or pay peak.
- Design changes mid-build – Every change costs double. Finalize drawings before ground breaks.
- No site supervision – Trust, but verify. A project manager pays for himself.
Using cheap materials to “save” budget?
Cheaper cement = weaker concrete. Thinner rods = weaker structure.
You save now. You pay for it for 20 years.
Materials in 2026: Buy smart or pay more
Cement: ₦11,500 – ₦15,000 per bag.
Steel, granite, sand – all up 40%+ since 2024.
A 4-bedroom that cost ₦86.7m in Jan 2024 cost ₦133.2m by Jan 2025.
In this market, when you buy matters.
Buy cement and steel early and you dodge the next hike. Wait and you pay spot market prices – the highest.
That’s why we built BACS: Buy Now, Pay Later for builders.
Direct from manufacturers. No middlemen. Payment terms that match your cash flow.
You lock today’s price without killing your mobilisation.

Materials are 60-70% of your cost. Get that wrong and nothing else balances.
