Building a 3-bedroom flat (about 100–120 sqm) in Nigeria costs roughly ₦22M–₦37M (~$16,000–$27,000) at a standard finish in October 2026, before land. A basic finish brings that down to around ₦18M–₦30M (~$13,100–$21,800), while premium finishes push it to ₦40M–₦70M+ (~$29,100–$50,900). Finishing, not the structure, moves your final number most. (Figures at ₦1,375/$, October 2026.)
Updated 21 October 2026: this page now brings together four older Lands of Nigeria guides on the same question, rebuilt on our Q4 2026 price tracker. If you followed a link to one of the old pages, you’ve landed in the right place.
Here’s the thing about 3-bedroom flat estimates online: they disagree wildly, and most never say when they were last checked. Cement alone has gone from about ₦9,300 a bag in January 2026 to ₦12,000–₦15,000 now. So below we tie every number to this quarter’s prices and show you how we got it, so you can walk into a contractor’s quote knowing whether it’s fair.
How much does it cost to build a 3-bedroom flat in 2026?
Your finish level decides your budget more than anything else. The same floor plan can cost ₦18M or ₦70M depending on tiles, fittings, ceilings and windows. Here’s the October 2026 range for a single 100–120 sqm flat, construction only.
| Finish level | Build cost (₦) | ~ USD | What you get |
|---|---|---|---|
| Basic | ₦18M – ₦30M | ~$13,100 – $21,800 | Sound structure, simple tiles and fittings, painted walls |
| Standard / modern | ₦22M – ₦37M | ~$16,000 – $26,900 | Good tiling, POP ceilings, aluminium windows, branded sanitaryware |
| Premium | ₦40M – ₦70M+ | ~$29,100 – $50,900+ | Imported tiles and fittings, fitted kitchen and wardrobes, smart features |
Standard tier = 100–120 sqm × ₦215,000–₦310,000 per sqm, the all-in Lagos rate in our Q4 2026 Construction Cost Tracker. Basic is about 20% below that; premium starts above ₦400,000 per sqm. Excludes land.
Where the money goes: cost by stage
Most people picture the walls as the big cost. In reality, finishing usually takes the largest share. Here’s roughly how a ₦30M standard flat splits. Use the percentages, since the naira figures move with the market.
| Stage | Share of build | On a ₦30M flat (₦) | ~ USD |
|---|---|---|---|
| Foundation & substructure | 10–15% | ₦3M – ₦4.5M | ~$2,200 – $3,300 |
| Walls & frame (blocks, cement, rods) | 15–20% | ₦4.5M – ₦6M | ~$3,300 – $4,400 |
| Roofing | 10–15% | ₦3M – ₦4.5M | ~$2,200 – $3,300 |
| Finishing (plaster, tiling, POP, paint) | 25–35% | ₦7.5M – ₦10.5M | ~$5,500 – $7,600 |
| Plumbing & electrical | 10–15% | ₦3M – ₦4.5M | ~$2,200 – $3,300 |
| Doors, windows & fittings | 10–15% | ₦3M – ₦4.5M | ~$2,200 – $3,300 |
For the raw quantities behind the walls, our blocks-and-cement guide shows how many blocks and bags a 3-bedroom footprint needs. For two of the big finishing lines, see our roofing and tiling cost guides.
Material prices behind these numbers (October 2026)
These are the Lagos prices that drive a 3-bedroom flat budget this quarter. The full list, with changes since Q3, is in our cost tracker.
| Item | Unit | Price (₦) | ~ USD |
|---|---|---|---|
| Cement | 50kg bag | ₦12,000 – ₦15,000 | ~$8.70 – $10.90 |
| 9-inch block | piece | ₦750 – ₦950 | ~$0.55 – $0.69 |
| Iron rod, 12mm | length | ₦9,500 – ₦11,000 | ~$6.90 – $8.00 |
| Sharp sand, delivered | 20-ton tipper | ₦150,000 – ₦250,000 | ~$110 – $180 |
| Mason (Lagos) | day | ₦14,000 – ₦18,000 | ~$10 – $13 |
Building one flat or a whole block?
Each flat in a block costs less to build than a standalone flat of the same size, because the units share a foundation, roof, staircase and external works. That’s why investors usually build two-storey blocks of four or six flats. If that’s your plan, use our separate guide to the cost of building a block of flats, which prices whole blocks rather than single units.
What drives the price up, or down
Location. Lagos and Abuja cost the most because of haulage and labour; a smaller city can come in 15–25% cheaper for the same plan. Within Lagos, the Lekki axis often needs extra sand-filling and deeper foundations.
Finish choices. Imported tiles, wardrobes and smart fittings can add ₦10M or more on their own. This is the dial you actually control.
Site conditions. Waterlogged or sloping land means deeper foundations and sand-filling, sometimes millions before you lay a single block.
Timing. A flat takes months to build, and prices move the whole time. Buy cement and rods in bulk when you can; rods eased slightly this quarter while blocks and cement rose.
Worth knowing: a fair contractor prices from a bill of quantities tied to your drawings. A round “₦30 million” with no breakdown is a red flag, not a quote. Ask to see the stages and unit rates.

What most 3-bedroom flat estimates leave out
Land isn’t in the number. Nearly every “cost to build” figure online, including ours, excludes land. On the Lekki axis or in central Lagos, the plot can cost more than the building.
Professional fees and approvals. Architect, structural engineer and quantity surveyor fees, plus building-plan approval, are real line items. Skipping approval is how builds get sealed or demolished; see our Lagos demolition red flags.
Price movement during the build. Hold a 10–15% contingency, or the last stages will ambush you.
The finishing trap. Owners routinely blow the budget at finishing because it’s the visible, emotional stage. Decide your finish tier before you start, and hold the line.
Watch out: a quote far below these ranges usually means thin foundations, weak blocks or “cost management” you’ll pay for later in cracks and leaks. Save on finishes, never on structure.
Frequently asked questions
How much does it cost to build a 3-bedroom flat in Nigeria in 2026?
About ₦22M–₦37M (~$16,000–$27,000) at a standard finish for a 100–120 sqm flat in October 2026, excluding land. A basic finish costs around ₦18M–₦30M; premium finishes run ₦40M–₦70M or more.
How much does it cost to build a 3-bedroom flat in Lagos?
Lagos sits at the top of these ranges because labour and haulage cost more; a standard flat is about ₦22M–₦37M (~$16,000–$27,000) before land. Smaller cities can be 15–25% cheaper for the same plan.
Does the cost include land?
No. These are construction-only figures. Land is a separate and often larger cost, especially in Lagos.
What’s the biggest cost when building a flat?
Finishing (plaster, tiling, POP, painting and fittings) usually takes 25–35% of the build, more than the foundation or the walls.
Is it cheaper to build flats in a block?
Yes, per flat. Units in a block share the foundation, roof and stairs, so each costs less than a standalone flat. See our block of flats cost guide.
Methodology & sources: cost tiers are planning estimates for a single 100–120 sqm 3-bedroom flat, construction only, built from the per-square-metre rates and October 2026 material prices in our Construction Cost Tracker, which draws on dealer reports from Legit.ng and the NigeriaBuildingCost price index. Stage shares are standard Nigerian residential splits. Your exact cost needs a bill of quantities on your own drawings. This page consolidates four earlier LON guides (2025–2026). Dollar figures at ₦1,375/$ (parallel market, 8 October 2026). Last updated: 21 October 2026. Next review: January 2027.
