How Developers Cut Corners When Building Houses in Lagos, What Buyers Must Know in 2026

Lagos is booming. Cranes hang over every major road on the Island. New developments spring up across Lekki, Ikoyi, Ajah, and the Mainland every single month. The city’s real estate market is one of the most active in West Africa, and there is real money to be made in property.

But behind the glossy renders, the beautiful show flats, and the promises of luxury living, something ugly is happening. Some developers cut corners when building houses in Lagos, and the consequences range from cracked walls and leaking roofs all the way to buildings collapsing with people inside them.

If you are planning to buy a property in Lagos in 2026, this article is not here to scare you. It is here to arm you with the truth so you can tell the difference between a developer who builds properly and one who is gambling with your investment and your safety.

The Numbers Tell a Disturbing Story

Let us start with the data, because this is not an opinion. According to the Building Collapse Prevention Guild (BCPG), Nigeria recorded 679 building collapses and over 1,639 deaths between 1974 and 2024. Lagos alone accounted for 53.9% of every single building collapse in the country during that period. That is more than every other state combined.

The trend is not slowing down. TheCable reported that in just the first half of 2025, Lagos recorded at least six building collapse incidents, killing 14 people and injuring many more. The BCPG’s 2024 report updated the national figure to 653 incidents and 1,616 deaths. Ahmed Dangiwa, Nigeria’s Minister of Housing and Urban Development, publicly described the frequency of building collapses as a national embarrassment.

And here is the part that should concern every buyer. Punch reported that the Nigerian Institute of Building (NIOB) found that 80% of building collapses in Nigeria were linked to unqualified builders and poor project oversight. A 2024 Lagos State Building Control Agency (LASBCA) report found that 40% of ongoing construction projects in the state lacked proper approvals or had structural concerns.

These are not freak accidents. These are the consequences of developers who cut corners when building houses in Lagos, and a system that too often lets them get away with it.

Corner #1: Skipping Proper Soil Tests and Using the Wrong Foundations

This is one of the most common and most dangerous ways developers cut corners when building houses in Lagos. It happens constantly in the Lekki-Ajah corridor, and many buyers never even know to look for it.

Large parts of Lekki and Ajah sit on what was once swampland. The soil is waterlogged, weak, and requires special engineering attention. For most multi-storey buildings in these areas, the correct foundation type is a pile foundation, where deep concrete columns are driven into the ground until they reach stable soil or bedrock. Pile foundations are expensive. They can cost several million naira more than the cheaper alternative.

That cheaper alternative is a raft foundation, which is a flat concrete slab that spreads the building’s weight across a wide area. Raft foundations are perfectly fine for low-rise buildings on stable ground. But they are not always appropriate for the soil conditions in places like Lekki and Ajah.

As Vanguard reported, Yusuf Odumade, CEO of Darryl Homes Nigeria Limited, specifically called out this practice. He noted that the Lekki-Ajah axis is water-filled land that mostly requires pile foundations, but some developers cut corners and use raft foundations just to be cost-effective. The result, he said, is that their houses crack and they sometimes have to demolish or spend extra money repairing what should have been done properly from the beginning.

When you are shopping for a property in Lekki Phase 1 or anywhere along the Lekki-Ajah axis, ask the developer what type of foundation was used. Ask to see the geotechnical soil report. If they cannot produce one, that is a red flag.

Corner #2: Using Substandard Building Materials

This one is as old as construction itself, but it remains rampant. Developers who cut corners when building houses in Lagos often save money by sourcing cheaper, lower-grade materials. We are talking about low-quality cement, weak steel reinforcement bars, adulterated concrete, and inferior plumbing and electrical fittings.

ThisDay reported that defective building materials and poor quality control are among the leading causes of structural failure in Lagos. The article noted that about 78% of collapsed buildings in Lagos between 2000 and 2021 were residential properties, meaning the people most affected are everyday homebuyers and tenants.

The problem is that substandard materials are not always visible to the naked eye, especially after the building is plastered, painted, and finished. A wall can look perfectly smooth on the outside while hiding weak blocks and insufficient reinforcement underneath. This is why third-party structural inspections before purchase are so important.

When a developer builds in Lekki, buyers should ask about the grade of concrete used, the source and size of reinforcement steel, and whether the developer conducted material testing at an accredited laboratory during construction.

Corner #3: Exceeding Approved Building Plans

This is one of the most brazen ways developers cut corners when building houses in Lagos, and the 2021 Ikoyi building collapse remains its most devastating example.

On November 1, 2021, a 21-storey luxury high-rise under construction on Gerrard Road in Ikoyi collapsed, killing at least 44 people. Wikipedia’s account of the incident details how the building’s engineering consultancy firm, Prowess Engineering Limited, withdrew from the project in February 2020 over concerns about the structural integrity of the building. The general manager of LASBCA at the time stated that the developer had been approved for 15 floors but built 21.

As Brookings documented in their analysis, this was not an isolated case. There are no federal or state regulations in Nigeria that mandate developers to consult certified professionals for building construction. This regulatory gap allows unqualified builders to oversee projects and allows developers to alter plans after approval with little fear of consequences.

A coroner’s inquest into the Ikoyi collapse later found that the building’s density and setback showed gross violations of the Lagos State Building Regulations. The project board, which should have displayed the names and credentials of the professionals involved, was deliberately not provided.

For buyers, this means you should never assume a building was constructed according to the plan shown in a marketing brochure. Request to see the actual building permit and approved plans from LASPPPA (Lagos State Physical Planning Permit Authority) and confirm they match what was built.

Corner #4: Hiring Unqualified Workers and Skipping Professional Oversight

Qualified structural engineers, architects, and certified builders cost money. So some developers cut corners when building houses in Lagos by hiring unlicensed professionals or cutting out key roles entirely. They might use an architect for the initial design to get planning approval, then hand the actual construction over to a foreman with no engineering qualifications.

HumAngle’s investigation into Lagos building collapses revealed how this works in practice. Developer Kehinde Fayegbami told the publication that substandard materials, lack of compliance with building standards, and corruption within monitoring bodies are the main drivers. He explained that some developers apply for a three-storey building permit and then go ahead and build ten storeys without any qualified engineer on site to assess whether the structure can handle the additional load.

The NIOB has stated that 80% of building collapses are linked to unqualified builders and poor project oversight. That is an extraordinary figure. It means that the single biggest risk factor in Nigerian construction is not the weather, the soil, or the materials. It is the people doing the building.

When evaluating a developer, ask who their structural engineer is. Ask who their architect is. Ask whether COREN (Council for the Regulation of Engineering in Nigeria) registered professionals were involved throughout construction, not just at the design stage.

Corner #5: Rushing Curing Times and Construction Schedules

This is the corner-cutting method that buyers rarely hear about, but it is extremely common. When concrete is poured for slabs, columns, and beams, it needs time to cure. Curing is the process by which concrete gradually reaches its full strength. For most structural concrete, proper curing takes at least 28 days under the right moisture and temperature conditions.

Developers who cut corners when building houses in Lagos often do not allow concrete to cure properly because it slows down the project timeline. Every extra week on site costs money in labour, equipment rentals, and security. So they rush it. They strip formwork too early. They load weight onto slabs before the concrete has reached its design strength. TheCable noted that this practice directly compromises structural integrity and leads to weaker buildings that are more likely to fail over time.

The result is not always a dramatic collapse. Sometimes it shows up years later as cracking along slab edges, deflection in beams, or gradual settlement of the building. By the time a buyer notices, they have already paid, moved in, and the developer has moved on to the next project.

Corner #6: Bribing Regulators Instead of Meeting Standards

This is the part nobody wants to talk about openly, but the data makes it undeniable. Lagos has regulatory agencies that are supposed to prevent all of the above. LASBCA handles building control. LASPPPA handles planning permits. The Lagos State Materials Testing Laboratory tests construction materials. On paper, the system looks robust.

In practice, ThisDay reported that bribery and exploitation are significant contributors to building failures. Building drawings sometimes pass through approval processes without being properly reviewed because developers offer incentives to officials. Substandard plans get rubber-stamped. Violations during construction go unreported.

Brookings noted that the failure of government at different levels to prosecute those responsible for building collapses has created a culture of impunity among developers. Despite the existence of building control laws in Lagos, the lack of consistent enforcement means that developers who cut corners when building houses in Lagos often face no meaningful consequences, even after people die.

What Smart Buyers Should Do in 2026

Understanding how developers cut corners when building houses in Lagos is only useful if you know how to protect yourself. Here is what to do before you hand over your money.

• Verify the building permit. Every legitimate construction project in Lagos must have an approved building plan from LASPPPA. Ask to see it. Confirm it matches what was actually built.
• Ask about the foundation. Especially in Lekki and Ajah, ask whether a geotechnical soil investigation was conducted and what foundation type was used. If the developer cannot answer confidently, walk away.
• Request material test reports. Reputable developers test their concrete, steel, and other materials at accredited labs during construction. Ask to see the cube test results for the concrete used.
• Check for COREN-registered professionals. Ask who the structural engineer and architect are. Verify their registration with COREN and the Architects Registration Council of Nigeria (ARCON).
• Hire an independent structural surveyor. Before you buy, pay a qualified professional to inspect the property. This is not an optional extra. It is a necessity in a market where regulatory enforcement is inconsistent.
• Research the developer’s track record. Look at their previous projects. Visit completed buildings. Talk to existing residents. A developer with a pattern of quality does not suddenly start cutting corners. And a developer with a pattern of cutting corners does not suddenly start building well.
