Construction mistakes in Lagos can turn dream projects into nightmares where one can have collapsed buildings, legal battles, and wasted budgets. At Realistic Projects Limited, we’ve identified the 3 most critical errors developers make and how to avoid them. Lagos is a bustling hub of real estate and construction, but the fast-paced nature of development often leads to costly mistakes. In a city where the skyline is rising fast, the dangers lurking beneath poorly planned construction projects can be devastating. According to the Lagos State Building Control Agency (LASBCA), many building collapses in Lagos are traced to three preventable construction mistakes: poor structural design, inadequate soil testing, and the use of substandard materials.
Just recently, high-rise developments in areas like Lekki and Ikoyi have faced financial losses running into hundreds of millions of naira due to these avoidable errors. One such incident involved a project that reportedly lost over ₦200 million simply because the soil beneath the foundation wasn’t properly tested.
At Realistic Projects Limited, our team has supported a growing number of residential and commercial developers in Lagos and across Nigeria. By focusing on detailed planning, professional design, and strict adherence to building standards, we help clients sidestep these costly mistakes before they even begin. Let’s dig in.
To help you avoid common pitfalls, we’ve compiled 3 major construction mistakes in Lagos and steps to prevent them.
Lagos construction Mistake #1: Poor Soil Testing Risks.
The Hidden Risks
Lagos’ soil varies wildly from marshy wetlands (Victoria Island) to unstable sand (Epe). Skipping a geotechnical survey is like building on quicksand.
Real-World Consequences
- Case Study: A client in Ikoyi ignored soil tests, only to discover mid-construction that the site required 40-meter piles (cost: N75M extra).
- Cost Comparison: A N500,000 soil test could prevent N50M in foundation repairs.
How to Avoid It:
✔ Test before buying land (we use Dutch Cone Penetration tests for accuracy).
✔ Adapt foundations:
- Marshy areas: Pile foundations
- Sandy zones: Raft foundations
✔ Hire LASBCA-certified geotechnical engineers
Choosing the right engineering partner is just as critical as soil tests. Read our guide on How to Select the Right Design & Engineering Partner for your project.

Why?
Because this reinforces the need for qualified professionals in foundational work.
Lagos construction Mistake #2: Ignoring Building Regulations & Permits.
The Mistake:
The Legal Nightmares
In recent years, LASBCA has intensified its crackdown on illegal structures across Lagos, with dozens already demolished and more marked for removal. Under updated urban planning regulations, penalties for non-compliance have become significantly stricter—with fines now reportedly running into millions of naira for defaulters.
Permit Timeline
- Pre-construction inspection (1-2 weeks)
- Approval of architectural drawings (3-4 weeks)
- Stage certifications (foundation, roofing, completion)
How to Avoid It
✔ Start early: Permits take 4-8 weeks (we expedite to 2-3 weeks for clients).
✔ Use our LASBCA checklist.
✔ Never bribe officials—it voids insurance claims.
Smart planning goes beyond permits. Learn how to create compliant, future-proof designs in our article on Smart Building Plans for Nigerian Projects.

Why?
It ties regulations to intelligent design principles.
Lagos construction Mistake #3: Using substandard materials to cut costs
Deadly shortcuts
Substandard construction materials remain a significant threat to building safety in Lagos. The Standards Organization of Nigeria (SON) has identified the use of such materials, including low-quality cement and steel reinforcement bars, as a major factor contributing to structural failures. Ensuring the quality and compliance of these materials is crucial to preventing building collapses and safeguarding lives.
SON’s approved material list helps verify suppliers.
Spotting Fakes
- Cement: Check for NIS markings and batch numbers.
- Steel: Demand MANCAP certification and mill certificates.
How to Avoid It
✔ Buy from our vetted suppliers (DM for list).
✔ On-site tests: We use Rebar scanners and concrete slump tests.
✔ Ask these 10 questions before hiring a contractor
The wrong contractor often means poor material choices. Avoid this by asking these 10 Critical Questions Before Hiring a Construction Firm.

FAQs: Lagos Construction Mistakes
1. “Can I reuse a neighbor’s soil test report?”
No! Soil composition changes within 500 meters. Always test your exact site.
2. “What’s the #1 material mistake in Lagos?”
Using “Grade 25” cement for high-rises (requires Grade 42.5).
3. “Do I need permits for renovations?”
Yes, if structural (e.g., removing walls).
