As of mid-2025, Africa’s affordable housing ambitions are under siege—not by lack of will, land, or vision, but by a subtler and more insidious force: the skyrocketing cost of building materials. From cement and steel to finishing fixtures and imported fittings, prices have soared across the continent, pushing construction budgets far beyond reach and pricing out both developers and prospective homeowners.
In Nigeria, Ghana, Kenya, and beyond, the dream of home ownership is now threatened by inflationary pressures rooted in both global supply chains and local economic decisions. The silent crisis is quietly transforming housing economics, and unless tackled head-on, it could unravel decades of policy planning.
FX Volatility: When Exchange Rates Redesign Your Blueprint
For most African nations, the cost of building materials is inextricably tied to foreign exchange markets. Nigeria’s naira, Kenya’s shilling, and Ghana’s cedi have all seen sharp devaluations in the past 24 months. The consequence? A staggering increase in the local currency cost of imported materials.
In Nigeria alone, the naira fell by over 65% against the dollar between Q1 2023 and Q2 2025, pushing up prices for imported tiles, sanitary wares, lighting, and even roofing sheets. Developers now require up to 40% more in naira to complete the same structure compared to two years ago.
Local Manufacturing Isn’t Filling the Gap
The policy answer often floated is local production. But in practice, many African countries lack the industrial infrastructure to produce building inputs at scale.
While cement and basic iron rods may be produced domestically, advanced fittings, high-grade finishes, aluminum frames, and plumbing systems are still heavily reliant on imports. Even local manufacturers are not spared: they import machinery, components, and sometimes even raw materials—making them equally vulnerable to FX and supply chain shocks.
In Nigeria, Dangote Cement and BUA dominate local production, but transport bottlenecks, energy costs, and limited rail networks push up retail prices.
Government Policy: Import Bans With Unintended Consequences
Policy decisions, particularly import restrictions, have also exacerbated the crisis. A well-meaning attempt to encourage local industries has, in some instances, created scarcity and encouraged smuggling.
In 2024, Nigeria expanded its FX exclusion list to cover several building components. What followed was a sharp jump in prices as unofficial parallel market FX rates became the new standard for pricing.
In Kenya, VAT on imported steel and pipes contributed to a 22% spike in building costs within a year, according to the Kenya Property Developers Association (KPDA).
Infrastructure Deficit: The Hidden Cost Driver
Transportation remains one of the most overlooked cost drivers. Poor road networks, limited rail freight, and port congestion inflate the logistics costs of moving materials.
In Lagos, developers estimate that 12–18% of the cost of housing units stems from transporting materials alone. A bag of cement produced in Kogi State may cost nearly double by the time it gets to Rivers or Bayelsa, due to multiple taxation and poor logistics.
Developers Caught in the Crossfire
Developers operating in mid-income and affordable housing segments are finding it increasingly difficult to maintain promised price points. Many have paused projects or scaled back specifications. A few have opted for joint ventures or off-plan models to manage costs—yet these too carry trust and credibility risks.
In Ghana, a developer that began a housing project in 2022 with units priced at $25,000 is now listing similar units at over $37,000. The situation is pushing developers to seek unconventional material alternatives—from stabilized earth blocks to prefab systems.
Impact on Homeowners and the Informal Market
The cost shock is most pronounced for first-time homeowners and self-builders, many of whom operate outside formal mortgage frameworks. For these individuals, even incremental builds become unaffordable.
In Nigeria’s Benin and Aba cities, builders report a 70% increase in the price of cement since 2022. This has led to a rise in incomplete buildings and an informal rental surge, as people abandon personal builds for temporary shelter.
Data Snapshot: How Prices Have Moved (2022–2025)
- Cement (50kg): ₦3,800 → ₦7,500 (+97%)
- Iron rods (per tonne): ₦330,000 → ₦570,000 (+73%)
- Imported tiles (per sqm): ₦4,500 → ₦9,200 (+104%)
- Paint (20L bucket): ₦14,000 → ₦26,000 (+85%)

Policy Recommendations: What Must Change
- FX Stabilization Mechanisms: Central banks must adopt transparent FX frameworks and prioritize essential imports.
- Incentives for Local Input Production: Governments should support backward integration in key areas—e.g., ceramic tiles, electrical fittings.
- Transport and Infrastructure Investment: Reducing the logistical cost of moving materials can immediately cut housing expenses.
- Data Transparency: Real-time cost tracking across regions will help developers and policymakers respond faster.
- Public-Private Partnerships: Collaboration across finance, logistics, and manufacturing can unlock scale efficiencies.
Conclusion: The Inflationary Wall Between Policy and Possibility
Africa’s affordable housing drive is being quietly eroded by a systemic cost crisis. While headlines focus on land and policy, the walls of homes are being priced out before they’re ever built.
To realize true housing affordability, the continent must confront the inflationary headwinds in its supply chains. From FX reform to local production and better transport infrastructure, a new kind of intervention is required—one that looks beyond units built to what it truly costs to build them.
FAQs
1. Why are building materials in Africa becoming so expensive?
Due to FX fluctuations, import dependency, poor infrastructure, and inflation.
2. Is locally made cement cheaper than imported cement?
Yes, but prices are still high due to transport costs and energy overheads.
3. How can developers mitigate rising costs?
By using alternative materials, bulk purchasing, and adopting prefab or modular techniques.
4. Are government policies helping or hurting affordability?
Many well-meaning policies (e.g., import bans) are inadvertently raising costs.
5. What is the long-term solution?
A mix of local manufacturing, FX reform, infrastructure upgrades, and coordinated policy interventions.
