One of the most frequently asked questions in Nigerian construction is: "How much will it cost to build?" While costs vary significantly based on location, quality, and design, here's a realistic breakdown for 2025.
Foundation to DPC (Damp Proof Course)
This phase typically accounts for 15-20% of total construction costs. It includes excavation, foundation laying, and blockwork to DPC level. Budget between ₦3-5 million depending on soil conditions and location.
Superstructure and Roofing
From DPC to roof completion, expect to spend 30-35% of your total budget. This includes blockwork, lintels, roofing, and external rendering. For a standard 3-bedroom flat, this ranges from ₦6-10 million.
Internal Finishing
Plastering, tiling, plumbing, electrical work, doors, windows, and painting make up 35-40% of costs. Quality of finishes significantly impacts this figure. Budget ₦7-12 million for mid-range finishes.
Professional Fees
Architectural design, structural engineering, and project management fees typically add 10-15% to construction costs. While this may seem like an additional expense, professional oversight prevents costly mistakes.
Total Estimate
For a standard 3-bedroom flat with mid-range finishes in 2025, total costs range from ₦20-35 million, depending on location. Lagos and Abuja tend to be at the higher end, while other cities offer more affordable options.
