Addressing Housing Affordability In Nigeria Through Incremental Housing: An Evaluation Of The Millard Fuller Foundation (Mff) Model
Introduction
Housing affordability in Nigeria remains one of the most persistent and complex challenges facing the nation today. With a housing deficit estimated at over 20 million units, a rapidly urbanizing population, and rising construction costs, millions of Nigerians find homeownership to be an unattainable dream. Traditional mass housing projects, often driven by government contracts, have repeatedly failed due to corruption, poor planning, and a one-size-fits-all approach that ignores the financial realities of low- and middle-income earners.
In response to this crisis, a growing number of development experts are turning to an alternative solution known as incremental housing. This approach allows families to build their homes in phases, expanding and improving as their income grows. At the forefront of this movement in West Africa is the Millard Fuller Foundation (MFF), a non-profit organization that has developed a unique model tailored specifically to the Nigerian context. This summary evaluates the MFF incremental housing model, exploring its effectiveness in addressing housing affordability in Nigeria, its core components, and its potential for scalability.
Understanding the Depth of Housing Affordability in Nigeria
Before analyzing the Millard Fuller Foundation model, it is critical to understand why housing affordability in Nigeria has reached crisis levels. The primary barrier is not just a lack of housing units, but a mismatch between supply and the purchasing power of the average citizen. More than 60% of Nigeria’s urban population lives in slums or informal settlements, paying exorbitant rents relative to their income. The conventional mortgage system in Nigeria is underdeveloped; interest rates often exceed 20%, and the required down payments are far beyond the reach of informal sector workers, who make up over 80% of the labor force.
Furthermore, the cost of building materials, such as cement and roofing sheets, has skyrocketed due to inflation and import dependencies. When the government or private developers build “low-cost” housing, the final price rarely falls below ₦10 million to ₦15 million (approximately $12,000–$18,000 USD), a sum that excludes the vast majority of households earning below ₦100,000 monthly. This financial chasm has led to a growing recognition that waiting for a completed, turnkey house is unrealistic. Consequently, incremental housing has emerged not merely as a preference, but as a necessity for survival and wealth creation.
What is Incremental Housing? A Core Definition
Incremental housing is a housing delivery process where families move into a core or minimal dwelling and gradually expand it over time. This is not a new concept; it has been successfully implemented in countries like Peru, Chile, and India for decades. The philosophy is simple: instead of requiring a family to purchase a fully finished four-bedroom house, they start with a serviced plot of land, a secure foundation, a single habitable room, and basic sanitation. Over five, ten, or fifteen years, as the family’s financial situation improves, they add bedrooms, a kitchen, a living area, and finishes.
For the context of housing affordability in Nigeria, this model is revolutionary. It reduces the initial capital outlay by 60% to 70%, allowing families to secure a roof immediately while building equity. It also aligns with the cultural reality of the Nigerian extended family system, where home improvements are often funded through remittances from relatives or cooperative societies (Esusu). However, the success of incremental housing depends heavily on the enabling environment: secure land tenure, access to low-cost building materials, technical guidance to prevent structural failure, and flexible financing.
The Millard Fuller Foundation (MFF): Origins and Philosophy
The Millard Fuller Foundation is named after the founder of Habitat for Humanity International. MFF was established in Nigeria to continue Fuller’s vision of eliminating poverty housing. Unlike many NGOs that focus on donations of completed homes, MFF has deliberately championed incremental housing as the most viable route to mass homeownership. Their flagship project, the MFF Housing Development in Jakande Estate, Ogun State (and subsequent sites), is a living laboratory for this approach.
The MFF model rests on three pillars: land security, core housing units, and a revolving loan fund. The foundation recognized early that for housing affordability in Nigeria to improve, beneficiaries must have legal title to their land. Without a title, families will not invest in incremental improvements because they fear eviction. MFF works with state governments to secure and survey land, providing beneficiaries with a legal “Certificate of Occupancy” before construction begins.
A Deep Dive into the MFF Incremental Housing Model
The Millard Fuller Foundation model is structured into specific, replicable phases. To understand its effectiveness, we must examine each component in detail.
Phase 1: The Serviced Plot and Core House
The entry point for an MFF beneficiary is not a finished house but a serviced plot of land (typically 300–400 square meters) that includes a core house. The core house is a durable, lockable structure of about 20 to 30 square meters. It contains one room, a pit latrine or simple toilet, and a veranda. The walls are made of sandcrete blocks, and the roof is corrugated metal sheets. This core unit costs significantly less than a standard one-bedroom flat on the open market. As of the document’s evaluation, an MFF core house was priced at roughly one-third of a conventional “low-cost” house.
Phase 2: Infrastructure and Services
A key differentiator of MFF from slum upgrading is that they provide planned infrastructure from the start. The estate includes graded roads, drainage channels, boreholes for water, and electricity poles. This pre-planning is crucial for incremental housing because it prevents the chaos of unregulated expansion. Families know where their property lines are, where the sewage line will run, and where to add future rooms without violating building codes.
Phase 3: Flexible Financing via a Revolving Loan Fund
MFF does not give houses away for free; that model is unsustainable. Instead, they offer a lease-to-own or micro-mortgage product. Beneficiaries pay a modest down payment (as low as 10-15%) and then make monthly installments over 5 to 10 years. Crucially, these payments are often lower than the rent they would pay for a single room in Lagos or Ibadan. As families pay off the core house, they qualify for “top-up” loans specifically for incremental expansion adding a bedroom, plastering walls, or tiling floors. This revolving fund is recapitalized by repayments, allowing MFF to serve more families over time.
Phase 4: Technical Assistance and Material Supply
Many incremental housing projects fail because families use unskilled labor or substandard materials, leading to building collapse. MFF provides free technical oversight. They offer approved building plans for different expansion stages (core, starter, intermediate, finished). They also operate a bulk-purchasing program for cement, blocks, and roofing sheets, passing wholesale discounts to beneficiaries. This directly addresses one of the biggest obstacles to housing affordability in Nigeria: volatile material prices.
Evaluating the Successes of the MFF Model
The document provides compelling evidence that the MFF incremental housing model delivers tangible results where government programs have failed.
Success 1: Affordability and Accessibility
By lowering the entry price to approximately ₦2.5 million to ₦3.5 million for a core house with land, MFF brought homeownership within reach of teachers, civil servants, petty traders, and artisans. Monthly repayments of ₦30,000–₦50,000 are manageable for families earning ₦80,000–₦120,000, especially compared to rent of ₦70,000+ for inferior accommodation in slums. This demonstrates that housing affordability in Nigeria is not about building cheaper finished houses, but about building affordable starter houses.
Success 2: Community Stability and Wealth Building
Evaluation data shows that MFF homeowners invest an average of 150% of their original core house cost into expansions within the first 4 to 6 years. This injection of capital into home improvements creates local jobs for masons, carpenters, and painters. Furthermore, families reported a sense of psychological security and pride that was absent when they were renting. Children’s school attendance improved, and small home-based businesses (shops, hairdressing salons) proliferated in the completed homes. The model transforms housing from a consumptive expense (rent) into a productive asset (equity).
Success 3: Low Default Rates
Contrary to fears that low-income borrowers will not repay, the MFF revolving loan fund saw default rates below 8% over a five-year period. This is significantly better than Nigeria’s commercial mortgage default averages. Why? Because the incremental housing model builds ownership gradually. Beneficiaries who have physically laid blocks, plastered walls, or added a door are psychologically committed to the property. They will cut other expenses before missing a payment. Additionally, the social contract within the MFF estate neighbors holding each other accountable reduces delinquency.
Success 4: Replicability and Scalability
The MFF model has been replicated in three states within southwestern Nigeria. Local governments have begun to donate underutilized land to MFF, recognizing that the foundation’s approach is more efficient than direct government construction. The document notes that for every ₦1 billion spent on MFF’s incremental housing, approximately 1,500 families are housed. The same budget spent on conventional “turnkey” housing by the government would house fewer than 400 families.
Challenges and Limitations of the MFF Incremental Housing Model
Despite its successes, the Millard Fuller Foundation model is not a panacea for the entire national housing deficit. Several critical challenges persist.
Challenge 1: Land Title and Bureaucracy
While MFF secures land titles, the process of obtaining a Certificate of Occupancy in Nigeria can take 12 to 24 months due to state bureaucracy. This delay frustrates beneficiaries and ties up capital. Furthermore, in some cases, MFF has faced encroachment issues from local chiefs or land grabbers (omo onile), requiring expensive legal battles. Without systemic land reform across Nigeria, even the best incremental housing models will struggle to scale nationally.
Challenge 2: The “Missing Middle” of Finance
The MFF revolving fund relies on donor grants and soft loans from international partners (e.g., Habitat for Humanity Global). This funding is finite. To truly solve housing affordability in Nigeria, MFF needs access to Nigeria’s Pension Fund or the National Housing Fund (NHF). Currently, the NHF is plagued by inefficiency and corruption, making it difficult for MFF to tap into. Beneficiaries also report that while the core house is affordable, the cost of incremental materials rises faster than their incomes due to double-digit inflation. MFF’s bulk purchasing helps, but it cannot fully insulate families from macroeconomic shocks.
Challenge 3: Construction Quality and Maintenance
The evaluation found that some core houses suffered from roof leaks and wall cracking within three years. This was attributed to the use of lower-grade materials to keep the initial price ultra-low. While MFF provides technical assistance, some families, eager to expand quickly, bypass approved plans and hire cheap, unskilled labor. This leads to structural irregularities and dangerous electrical wiring. MFF has had to create a “compliance team” to inspect expansions, adding to their operational costs.
Challenge 4: Perception and Social Stigma
In Nigeria’s status-conscious society, moving into a one-room core house is sometimes viewed as a step backward, even if it is on one’s own land. Some eligible families refused the MFF offer because they felt a “mini-house” was beneath their social standing. MFF has had to invest in community sensitization campaigns to reframe incremental housing not as poverty housing, but as strategic wealth building. Changing this mindset takes time.
Comparative Analysis: MFF vs. Government Mass Housing
To truly appreciate the MFF model, one must contrast it with the typical Nigerian government mass housing project. Government projects are characterized by: (a) contracts awarded to politically connected builders, (b) substandard work disguised by paint and finishing, (c) a requirement that houses be 100% complete before handover, leading to cost overruns of 200-300%, and (d) final prices that are inaccessible to the target low-income group. Consequently, many government “low-cost” estates sit empty for years, becoming ghost estates.
The MFF incremental housing model inverts this logic. It prioritizes volume over finish. A core house is ugly but functional; the beauty comes later through the family’s own sweat equity. The document argues that this “rough first draft” approach is precisely why housing affordability in Nigeria can be improved. It accepts imperfection as a stage, not a failure.
Recommendations for Scaling the MFF Model Nationwide
Based on the evaluation, several recommendations emerge for policymakers and development partners.
State-Level Enabling Acts: State governments should pass “Incremental Housing Acts” that legally recognize core houses as legitimate dwellings for building permit purposes. Currently, building codes often assume a finished house, making incremental expansion technically illegal. MFF’s success shows codes need to be phased.
Link to the National Housing Fund (NHF): The Federal Mortgage Bank of Nigeria should create a specific “Incremental Housing Window” within the NHF. This window would provide low-interest (single-digit) loans to families already living in MFF-style core houses for their expansion phases. This would supercharge the revolving fund model.
Tax Waivers on Core Building Materials: To further reduce the entry barrier, state governments should waive VAT and import duties on specific “core house” materials: cement, rebar, roofing sheets, and sanitary fittings. This would directly lower the initial cost by 10-15%, making incremental housing even more accessible.
Partnership with Informal Savings Groups (Esusu/Cooperative): MFF should formally integrate with local Esusu groups. Instead of just taking monthly loan repayments, MFF could act as a guarantor or matching fund provider. For every ₦10,000 a family saves in an Esusu for home expansion, MFF could provide a ₦5,000 grant or interest-free loan. This leverages existing cultural financial mechanisms.
Conclusion: A Blueprint for the Future of Housing Affordability in Nigeria
The Millard Fuller Foundation model is not a magic bullet, but it is arguably the most evidence-based, practical solution for housing affordability in Nigeria that currently exists. By shifting the paradigm from “turnkey finished homes” to incremental housing, MFF has demonstrated that low-income Nigerians can become successful homeowners when given secure land, a modest core structure, flexible financing, and technical support. The evaluation confirms that families are not only repaying their loans but are actively investing in and upgrading their properties, generating local economic activity and psychological well-being.
The challenges land bureaucracy, inflation, and social stigma are real but not insurmountable. They require political will and targeted policy interventions, not a rejection of the incremental approach. As Nigeria’s urban population continues to explode, waiting for the government to build millions of finished houses is a fantasy.
The future of housing in Nigeria will be built one room at a time, by the homeowners themselves, supported by models like that of the Millard Fuller Foundation. For NGOs, social enterprises, and even private developers looking to make a dent in the housing deficit, the MFF incremental housing model offers a replicable, financially sustainable, and humane roadmap. It proves that housing affordability in Nigeria is not an impossible dream it is a design problem, and incremental housing is a very good solution.
