Cost of building a house in Nigeria (2026)
25 September 2026 · 6 min read
Building costs in Nigeria have moved faster than anywhere else in this series. Cement went from about ₦9,500 a bag in January 2026 to ₦13,000–16,000 by August, so any figure, including these, needs a date beside it. Here is what a family bungalow costs to build as of the date below, and how to keep a budget honest while prices move.
A three-bedroom, two-bathroom house of about 125 m², standard finishes, built by a contractor in Lagos with a boundary wall, costs about ₦41 million all in — between ₦32 million and ₦51 million. Land is extra. The house alone is ₦160,000–230,000 per m². Rates checked September 2026.
The price per square metre
The rate per square metre is for the house alone. A house built by a contractor, including their margin, from foundations to finishes. It excludes land, fees, approvals and anything outside the walls. The totals here add what a real build also pays for — site preparation, drains and connections, a boundary wall and gate, plans and approvals, a 15% contingency and prices rising over a year-long build.
| Finishes | House, per m² | 3-bed, all in |
|---|---|---|
| Basicabout 85 m² | ₦120,000–160,000 | ₦22,300,000 |
| Standardabout 125 m² | ₦160,000–230,000 | ₦41,100,000 |
| High-endabout 175 m² | ₦250,000–400,000 | ₦89,400,000 |
A higher finish costs more per square metre and the rooms get bigger too, which is why the high-end house comes to more than twice the basic one.
By the size of the house
The same standard finishes, built by a contractor in Lagos, for a smaller or a bigger house:
| House | Floor area | All in |
|---|---|---|
| 2-bedroom house | 100 m² | ₦33,600,000 |
| 3-bedroom house | 125 m² | ₦41,100,000 |
| 4-bedroom house | 145 m² | ₦47,100,000 |
| 5-bedroom house | 170 m² | ₦54,500,000 |
Where the money goes, phase by phase
The standard house above, split the way it is built. Each phase carries its share of the contingency and of prices rising while it waits its turn. The split follows Legit.ng's costed 161 m² bungalow, September 2026.
| Phase | Likely | Share |
|---|---|---|
| Plans, approvals and fees | ₦1,570,000 | 4% |
| Site preparation | ₦827,000 | 2% |
| Foundation | ₦8,470,000 | 21% |
| Walls up to the roof | ₦6,410,000 | 16% |
| Roofing | ₦4,310,000 | 10% |
| Windows and doors | ₦2,450,000 | 6% |
| Electrical and plumbing | ₦4,230,000 | 10% |
| Plastering and finishes | ₦5,530,000 | 13% |
| Boundary wall, drains and paths | ₦7,290,000 | 18% |
| Total | ₦41,100,000 | 100% |
Budgeting by phase is what catches an overspend while there is still a choice to make: if the foundation has used its budget and the walls haven't started, you know now, not at the roof. More on that in construction costs by phase.
What moves the price
Where you build
Lagos sets the price. Against it:
- Port Harcourt: about 5% less
- Abuja: about 16% less
- Another city (Ibadan, Enugu…): about 22% less
- Rural home: about 28% less
From city-by-city rates for a standard build; Port Harcourt and rural homes are allowances.
Who builds it
Hiring your own builders and buying the materials yourself comes to about 11% less than a contractor. The contractor's margin goes, but more is lost to waste, theft and delays, and someone has to supervise every day — so it only saves money when someone you trust is on site.
The ground
- Clay or black cotton soil, dug out to firm ground and backfilled: about 6% more overall.
- Rock near the surface, broken out for the foundations: about 5% more.
- A sloping site, with stepped foundations and some retaining: about 6% more.
- Wet ground or near a wetland, usually a raft foundation, drains and a raised floor: about 24% more. It also needs approval from your state's planning and environment authorities before work starts, and some wetlands can't be built on at all.
Going up instead of out
The same 125 m² over two storeys comes to about 2% less. The footprint halves, so there is less foundation and roof, but the upper floor needs a concrete slab, a stair and a heavier frame.
Prices rising while you build
Materials in Nigeria are rising about 25% a year, so work done late in a build costs more than the same work done at the start. The totals here allow for a 12-month build starting now.
Extras most houses here need
| Item | Typical cost |
|---|---|
| Boundary wall, per metre | ₦21,000–46,000 |
| Gate (allowance) | ₦350,000–900,000 |
| Borehole, installed | ₦1,000,000–2,500,000 |
| Septic tank | ₦450,000–700,000 |
| Solar power for a family house | ₦2,000,000–3,500,000 |
Worth knowing about building in Nigeria
- Nigerian substructures run deep — sandfill, blockwork below ground, oversite concrete — so the foundation takes a far bigger share of the house than in Zimbabwe or Kenya.
- With prices rising around 25% a year, buying key materials early and releasing money phase by phase matters more here than anywhere else. The figures below allow for that rise over a year-long build.
- A fence wall for a standard plot, about 91 metres of it, runs roughly ₦1.9–4.2 million.
- Rates this volatile are rechecked every three months.
Where these figures come from
Every rate is quoted from a named, dated source, checked in September 2026. Where nothing published could be found, the figure is a quantity surveyor's allowance and marked as one.

An estimate from published rates is for budgeting, not a quote. Before you sign with a builder, get a bill of quantities priced for your plans and your plot.
Price your own house
The building cost calculator for Nigeria works from these same rates. Tell it the bedrooms, bathrooms, floors, ground and finish, and it prices your house phase by phase. In Trace My Build, one tap turns the estimate into phase budgets, and every payment after that is tracked against them.
Building somewhere else? Zimbabwe, Kenya, South Africa or Ghana.
