Building a house or commercial property is one of the biggest investments anyone can make. Across Africa, construction projects are booming—fueled by rapid urbanization, a growing middle class, and strong demand for modern housing. Yet, many projects fail to meet expectations due to common mistakes that can be avoided with the right knowledge and professional guidance.
At NTM Construction, we’ve seen these challenges firsthand and are committed to helping clients—especially those in the diaspora—overcome them. Below are some of the most frequent mistakes made during construction in Africa and how to avoid them, supported by real-life examples and expert insights.
1. Poor Planning and Design
Many projects begin without proper architectural drawings or detailed planning. Some owners rely on verbal instructions or rough sketches, which leaves too much room for error. Without a solid plan, contractors improvise, leading to mismatched designs, wasted materials, and higher costs.
Real-Life Example: In Kenya, skipping soil testing before foundation work has led to buildings sinking or cracking due to unsuitable terrain. In areas like Kitengela and Mombasa, poor planning has resulted in rising damp and structural instability. [Constructi…ing Errors]
Solution: Always start with a professional design and a clear project plan. At NTM, we involve customers in the design process and ensure every decision is documented before construction begins.
2. Using Low-Quality Materials
To cut costs, some contractors use substandard materials. This might reduce expenses in the short term but leads to weak structures, frequent repairs, and in some cases, unsafe buildings. Unfortunately, many diaspora clients discover too late that the materials they paid for were never used.
Real-Life Example: In Nigeria, over 354 people died in 91 collapsed buildings in Lagos alone between 2012 and 2023, often due to poor-quality materials and lack of oversight. [Structures…in Africa]
Solution: Invest in durable, high-quality materials and insist on transparency in purchases. NTM clients are included in material selection and given receipts and proof of every purchase.
3. Lack of Professional Supervision
In many cases, relatives or unqualified supervisors are left in charge of projects. Without technical knowledge, they cannot enforce quality standards or detect mistakes on site. This results in unfinished projects, wasted money, or buildings that don’t match the original design.
Real-Life Example: In East Africa, the BBJ building collapse was traced to poor supervision and incorrect implementation of reinforced concrete methods. [Failure of…ses of …]
Solution: Engage qualified professionals to manage your project. NTM assigns project managers and engineers to oversee every stage while keeping the customer updated and involved.
4. Ignoring Legal and Regulatory Requirements
Skipping permits, zoning laws, or building codes is a common mistake. This often leads to fines, halted projects, or even demolition of completed structures.
Real-Life Example: In South Africa, the Nelson Mandela Bay Metro Bus project failed due to poor planning and lack of regulatory compliance, resulting in millions lost and buses left unused for years. [Examples o…ic library]
Solution: Work with professionals who understand local regulations. At NTM, we handle all necessary approvals to ensure projects comply with legal standards.
5. Excluding the Customer from Decisions
Too often, contractors make unilateral decisions—changing designs, materials, or finishes without consulting the owner. This is especially common for diaspora clients who cannot be physically present on site.
Real-Life Example: Many diaspora investors report discovering major changes to their projects only after completion, such as different tiles, layouts, or finishes than originally agreed. [5 Common C…rcome Them]
Solution: Customers should always be at the center of their projects. At NTM, we make our clients the Project Owners—involved in every decision, from materials to finishing touches. This ensures the final result is exactly what they envisioned.
