Everything we’ve discussed in this module — the mortgages, the institutions, the capital markets — is meaningless if nobody builds the houses. The construction sector is where policy meets concrete. Literally. And in Nigeria, that sector is simultaneously massive in scale and fragile in structure — like a giant standing on thin legs.

8.1.1 GDP Contribution and Growth

The construction sector contributed approximately 3.4-4 percent of GDP in 2024, with quarterly contributions ranging from 3.17 percent (Q2) to 4.01 percent (Q1). In absolute terms, the sector generated roughly N6.5 trillion in output. It ranks as the sixth-largest sector in Nigeria’s economy [1].

It’s important to distinguish construction from real estate. After GDP rebasing in 2025, the real estate sector (which includes property management, rentals, and real estate services) became Nigeria’s third-largest subsector at N41.3 trillion — displacing crude oil. But most of that real estate GDP comes from rental income and property services, not from new construction. The construction sector itself is smaller but more directly tied to housing delivery [1].

Growth has been uneven: 3.6 percent in 2023, slowing to 1.2 percent in 2024 (as high interest rates and material costs squeezed activity), before recovering to roughly 5.3 percent in 2025. The market is forecast to grow at an average of 3.1 percent annually through 2028, with total construction market value expected to reach N25.72 trillion in 2025 [2].

8.1.2 Employment — The Invisible Workforce

The construction sector employs an estimated 1.8 to 3.9 million workers depending on the data source and period. What’s certain is that the vast majority are informal: 93 percent of all Nigerian employment is in the informal sector (NBS Q2 2024), and construction reflects this pattern more than most industries. Most construction workers are daily-rate labourers with no employment contracts, no health insurance, no pension contributions, and no job security [3].

This matters for housing finance because the people who build houses are, by and large, excluded from the mortgage products that finance them. A bricklayer earning N5,000 a day — about N130,000 a month if he works 26 days — is technically within the income range for an NHF mortgage. But without a payslip, an employment letter, or NHF contribution history, the formal mortgage system can’t reach him. He builds the houses; he can’t buy them.

If you want to understand why Nigerian houses are expensive, start with what they’re made of. Building materials account for roughly 60 percent of total construction costs, and those costs have been on a relentless upward march. Between 2020 and 2025, the price of a bag of cement roughly quadrupled — from about N2,500 to over N10,000. Iron rods more than tripled. Aluminium roofing sheets rose 60-75 percent in a single year [4].

8.2.1 Cement — The Oligopoly Problem

Nigeria has installed cement production capacity of approximately 65 million tonnes per annum, controlled by three companies that account for over 95 percent of the market:

Nigeria has surplus cement production capacity — it can produce far more than the market consumes. Yet prices remain stubbornly high. The reason is market concentration: with three producers controlling 95 percent of supply, there’s little competitive pressure to reduce prices. It’s like having three petrol stations in a town of 100,000 people — technically enough capacity, but not enough competition to keep prices honest [4].

The price trajectory tells the story: approximately N2,500 per bag in 2020, rising to N4,300 by May 2023, then N7,500-8,000 by May 2024, and N10,000-10,500 by 2025. That’s roughly a 300 percent increase in five years. For a standard 3-bedroom bungalow requiring approximately 250-400 bags of cement, the cement cost alone has gone from about N625,000 to N2.5-4 million [4].

8.2.2 Steel and Iron Rods — The Import Trap

If cement is expensive because of oligopoly, steel is expensive because of import dependence. Nigeria’s steel industry never recovered from the Ajaokuta Steel Mill debacle (decades of investment, still not operational), and local rolling mills operate intermittently due to power supply problems and raw material shortages.

The result: 10mm iron rods jumped from approximately N335,000 per tonne in 2023 to N1,040,000 per tonne in 2025 — a 210 percent increase in two years. A standard 3-bedroom bungalow requires 2-4 tonnes of reinforcement steel, so the steel cost alone has risen from roughly N670,000-1.3 million to N2-4 million [5].

A $1 billion deal was signed with Indian firm Rashmi Metaliks in April 2026 to establish local steel production capacity. If it materialises, it could reduce import dependence over time. But for now, Nigerian builders are at the mercy of global steel prices and naira exchange rate movements.

8.2.3 The 70 Percent Import Problem

According to the State of Lagos Housing Market Report (2025), approximately 70 percent of building materials used in Nigerian construction are imported. Despite having large domestic deposits of limestone, clay, sand, and timber, Nigeria lacks sufficient local processing capacity for many finished construction products. Every time the naira depreciates (as it has dramatically since 2023), import costs spike — and those costs flow directly into the price of houses [6].

Think of it like a restaurant that imports 70 percent of its ingredients. The food might be served in Lagos, but the cost is determined in Shanghai, Antwerp, and Dubai. Until Nigeria develops more local manufacturing capacity for construction materials, housing costs will remain hostage to global supply chains and foreign exchange markets.

Let’s get concrete (pun intended) about what building a house in Nigeria actually costs. The numbers vary enormously by location, specification, and timing — but the ranges below reflect 2025-2026 market realities.

8.3.1 Regional Cost Comparison

A realistic budget for a standard 3-bedroom bungalow (excluding land) sits at roughly N20-36 million in Lagos, N16-25 million in Abuja, and N8-20 million in secondary cities. With land, the total in Lagos can easily exceed N50-100 million in desirable areas — and that’s for a bungalow, not a luxury villa [7].

8.3.2 The Budget Creep Problem

One of the most common experiences for Nigerian self-builders is budget creep — starting with one number and ending with a much bigger one. A Lagos homeowner documented their experience: they budgeted N28 million, but spent N36 million after soil testing (N200,000), building permits (N800,000), design changes mid-construction (N2.5 million), and material price increases during the building period (N4.5 million). That’s a 29 percent overrun — and it’s actually moderate by Nigerian standards [7].

For mortgage professionals, budget creep is a credit risk. A client who borrows N20 million to build a house that ends up costing N28 million will either abandon the project (creating a non-performing loan secured by an unfinished building) or seek additional financing at unfavourable terms. IMBLN practitioners should build contingency buffers of 15-25 percent into every construction-based mortgage recommendation.

8.3.3 Costs Versus Income — The Mismatch

Entry-level home prices in urban areas exceed 5-7 times average annual income — far above the global affordability benchmark of 3 times. With the median public-sector annual salary below N1.2 million, even the cheapest newly built urban home (N8-10 million in secondary cities) represents nearly a decade of pre-tax income. In Lagos, the ratio can exceed 20 times annual earnings for average workers [8].

This income-cost mismatch is the fundamental reason why mortgage finance alone cannot solve Nigeria’s housing problem. Even if you give everyone a 6 percent, 30-year mortgage, the houses themselves cost too much relative to what people earn. The supply side — reducing construction costs through materials reform, alternative technologies, and labour training — is just as critical as the finance side.

Building a house requires skilled hands. Nigeria has plenty of willing workers but a chronic shortage of properly trained ones — and that shortage drives up costs, extends timelines, and compromises quality.

8.4.1 The Wage Picture

Construction wages have risen sharply — 60 percent or more for skilled workers since 2023 — partly driven by inflation (workers need higher pay to afford the same goods) and partly by scarcity (not enough skilled artisans to meet demand). The irony is visible: masons earning N5,000/day are pricing themselves above the national minimum wage, yet the houses they build remain unaffordable to people earning that minimum wage [9].

8.4.2 The Skills Crisis

Academic research consistently identifies a chronic shortage of skilled construction artisans in Nigeria. Building sites face delays due to the unavailability of competent bricklayers, plumbers, electricians, and carpenters. Some developers prefer hiring foreign artisans (particularly from Togo, Benin Republic, and Ghana) because locally trained workers lack requisite skills in safety, precision, and modern techniques [10].

The root cause is the collapse of technical education. Nigeria’s vocational training system — once anchored by trade schools and the National Board for Technical Education — has been chronically underfunded for decades. The result is a generation of ‘artisans’ who learned on the job from other semi-skilled workers, perpetuating bad practices.

8.4.3 The Training Response

The government has launched several initiatives to address the skills gap. The National Artisan Skills Acquisition Programme (NASAP), launched in September 2025, is a pilot to train 3,000 artisans in three states across 10 priority trades including bricklaying, plumbing, electrical, carpentry, and painting. The Skill Up Artisans Programme (SUPA), launched in 2024, has enrolled over 100,000 youths across construction, ICT, and manufacturing. The Industrial Training Fund (ITF) targets training 5 million artisans annually through skills acquisition centres nationwide [10].

These programmes are a start, but the scale is mismatched: training 3,000 artisans when the sector needs hundreds of thousands is like administering eye drops in a rainstorm. Closing the skills gap requires sustained, multi-year investment in technical education at a fundamentally different scale.

Nigeria has a National Building Code. It has the Standards Organisation of Nigeria. It has professional bodies (COREN for engineers, NIA for architects, NIOB for builders). On paper, the regulatory framework for construction quality is adequate. In practice, enforcement is patchy at best and absent at worst.

8.5.1 The National Building Code

First issued in 2006, the National Building Code provides standards for structural integrity, fire safety, energy efficiency, and accessibility. Updates in 2024-2025 strengthened fire safety measures, mandating sprinklers, fire alarms, and fire-resistant materials in commercial and high-rise buildings. The code is enforced primarily at the state level through Urban and Physical Planning Boards and Building Control Agencies. In Lagos, the Lagos State Building Control Agency (LASBCA) is the most active enforcement body in the country — conducting inspections, issuing construction approvals, and granting occupancy certificates [11].

Outside Lagos, enforcement ranges from inconsistent to non-existent. Many states lack dedicated building control agencies. Inspections are infrequent. Developers build without permits. And when buildings collapse — as they regularly do in Lagos, Port Harcourt, and elsewhere — the investigations reveal that basic code requirements were never followed.

8.5.2 Building Permits

In Lagos, building permits are processed through the LASPPPA (Lagos State Physical Planning Permit Authority) via an online e-Planning system. The official timeline is 28 days after screening and payment, though practical timelines are more like 60-90 days with complete documentation and potentially 6-12 months with incomplete files. Costs range from N20,000 to N3 million depending on project type, size, and zone [11].

For mortgage professionals, the building permit issue intersects with property valuation and title verification. A property built without a permit — or in violation of its permit — may face demolition orders, reducing its collateral value to zero. IMBLN practitioners advising clients on construction-based mortgages should verify permit status as part of their due diligence.

8.6.1 REDAN

The Real Estate Developers Association of Nigeria has over 2,000 registered developers and serves as the organised private sector’s umbrella body for housing development. REDAN has been the first port of call for federal and state governments, NGOs, and international partners seeking private-sector housing delivery partners since receiving official government recognition in November 2002 [12].

REDAN members access Estate Development Loans from FMBN and participate in programmes like the Renewed Hope Estates. The association also serves as a quality filter — while membership doesn’t guarantee competence, it provides a degree of accountability that unregistered developers lack.

8.6.2 Major Private Developers

8.6.3 The PPP Model in Action

The Renewed Hope programme’s PPP structure represents Nigeria’s most significant current experiment in housing delivery partnerships. Developers source land and construction financing; the government provides the enabling environment (land allocation, infrastructure, regulatory approvals); and FMBN provides a Bankable Offtaker Guarantee ensuring that completed units will be purchased by NHF contributors through NHF mortgages [13].

The pricing difference between PPP and government-funded delivery is striking: a 1-bedroom unit in a PPP-driven Renewed Hope City costs approximately N22 million (because developers finance at commercial rates), while the same unit in a government-funded Renewed Hope Estate costs approximately N8.5 million (because the government absorbs infrastructure and financing costs). This gap illustrates the trade-off: PPPs leverage private capital and execution capacity, but they produce more expensive housing [13].

8.7.1 What Nigerians Build

The three most popular housing types in Nigeria are bungalows (single-storey, the most common outside Lagos), blocks of flats (dominant in Lagos and urban centres), and duplexes (terrace and detached, aspirational for the upper-middle class). Each serves a different market segment and price point:

8.7.2 What Counts as ‘Affordable’?

The standard international definition of affordable housing is housing where total costs (including maintenance and utilities) do not exceed 30 percent of household income. By this measure, the Renewed Hope Estates’ cheapest unit (N8.5 million for a 1-bedroom) is affordable for a household earning roughly N140,000 per month on a 30-year NHF mortgage at 6 percent. That’s achievable for a civil servant couple but out of reach for the majority of Nigeria’s workforce [14].

The hard truth: at current construction costs, genuinely affordable housing for bottom-of-pyramid Nigerians (earning below N50,000 per month) cannot be delivered through conventional construction and mortgage finance. It requires either massive government subsidies, alternative construction methods that dramatically reduce costs, or a shift from ownership-based models to rental housing.

Several alternative construction methods promise to reduce costs, speed up delivery, and improve sustainability. None has achieved mainstream adoption in Nigeria yet, but each represents a potential pathway:

Compressed Earth Blocks deserve particular attention for Nigeria. The country has abundant suitable soils, the technology is low-tech (requiring a manual or hydraulic press rather than expensive machinery), and the resulting blocks provide better thermal insulation than concrete blocks — reducing energy costs for cooling. Enugu builders report 20 percent cost savings using CEBs and other sustainable local materials [15].

3D printing generates the most headlines but faces the highest adoption barriers: expensive equipment, limited concrete formulations suitable for the technology, and a construction workforce that has never worked with robotic systems. Cipriani Limited is piloting 3D-printed housing in Nigeria, but mainstream adoption is likely a decade or more away [15].

The biggest barrier to all alternative methods is cultural: Nigerians overwhelmingly prefer conventional block-and-mortar construction. A house built with compressed earth or prefabricated panels is often perceived as inferior, even when it performs better technically. Changing this perception requires demonstration projects, public education, and — critically — financing. If PMBs and FMBN would lend against alternatively constructed homes at the same terms as conventional builds, the market signal would be powerful.

This lesson examined the supply side of Nigeria’s housing equation. The construction sector contributes ~3.4-4% of GDP and employs 1.8-3.9 million mostly informal workers, but the bulk of residential delivery is done by small operators and self-builders rather than the major construction firms. Building materials (60% of costs) have experienced dramatic inflation: cement ~300% in five years, iron rods ~210% in two years, with three producers controlling 95% of cement capacity. Seventy percent of building materials are imported, making costs hostage to forex volatility. A standard 3-bedroom bungalow costs N8-36 million to build (excluding land), and entry-level prices exceed 5-7 times average annual income. The labour force faces chronic skills shortages despite training programmes (NASAP, SUPA) that remain far below scale. Building standards exist (National Building Code, SON) but enforcement is weak outside Lagos. REDAN (2,000+ registered developers) and major private developers deliver housing through conventional and PPP models, with the Renewed Hope programme demonstrating the cost differential between PPP delivery (N22M/unit) and government-funded delivery (N8.5M/unit). Alternative construction methods (CEBs, prefab, 3D printing) offer 20-50% cost reduction potential but face cultural resistance and limited PMB acceptance as collateral.
