When you ask people how much you’ll be paying for a 3-bedroom bungalow in Lagos in 2026, you’ll hear a wide range of figures, and that range tells an important story about how much location, finishing and project management can affect the final bill.
Small builds outside the core areas of Lagos start at a conservative estimate of about ₦20 million. Premium builds with imported finishes in the more expensive areas of Lagos can run past ₦65 million, excluding land.
Land costs are usually the first and most unpredictable. A single plot can cost from a few hundred thousand Naira in the outlying areas to tens of millions in the more developed parts of the city, meaning that the cost of land alone can dwarf the construction budget depending on the location.
Buyers should also bear in mind, in addition to the purchase price, the expense of legal verification and processing of a Certificate of Occupancy, which protects against the disputes that dog informally purchased land.
Once the land is settled, the build itself breaks down into recognisable phases. Excavation, filling and reinforced concrete for the foundation and substructure can themselves cost several million naira, especially in places where the soil conditions demand deeper foundations.
Usually the biggest single line item is the superstructure work (block laying, columns and deck). Add to this several million pounds more depending on the complexity and material choice of the roof, whether aluminium sheets or the increasingly popular stone-coated steel.
Material costs remain the largest source of budget uncertainty. In 2026, cement has traded within a wide range, with the price of a 50kg bag anywhere from about ₦9,500 to ₦15,000 depending on brand, region and supply conditions.
Iron rods have followed a similar pattern with reported per-tonne prices of around ₦1.1 million earlier in the year, driven by naira movement, energy costs and global steel prices. Buyers are often advised to lock in bulk purchases early instead of buying material in stages as the naira and input costs move around.
It is the finishing, tiles, doors, windows, plumbing, electrical fittings and paint that most often sends budgets spiralling past original estimates, sometimes to as much as a third or more of the total cost of a project. This is also where buyers have the most flexibility on spend; locally sourced tiles and fittings versus imported alternatives can alter the finishing budget by millions.
Professional fees complete the picture. For a bungalow, architectural design usually ranges from about ₦150,000 to ₦300,000 for a simple plan but the scale of fees from the Nigerian Institute of Architects allows for percentage-based billing on larger or more complex projects.
In view of the volatility of material costs from month to month, most quantity surveyors now recommend adding a contingency of 15-20% onto the initial budget. This is a buffer that has become less of a luxury and more of a necessity in the current construction cost climate.
