FAQ

In Lagos/Abuja for 2026: A basic 3-bedroom bungalow (120–150 sqm): ₦18M–₦30M (basic finish). Standard 3-bedroom bungalow (150–200 sqm): ₦37M–₦55M. Standard 4-bedroom duplex (250–350 sqm): ₦72M–₦110M. Luxury 4-bedroom duplex: ₦125M–₦200M. Costs in other states (Ogun, Oyo, Anambra) are typically 15–30% lower. These figures have increased 40–60% from 2023 due to naira depreciation and cement/iron rod price increases.

Multiple factors since 2023: (1) Naira devaluation — most building materials (cement, iron rods, aluminum, electrical materials) are imported or have significant import content, so costs tied to USD have surged. (2) Fuel subsidy removal — increased diesel costs for generators, transportation, and concrete mixers. (3) Global supply chain disruptions. (4) Increased demand. Budget for a 20–30% cost escalation buffer for projects extending beyond 6 months.

Key strategies: (1) Hire a qualified quantity surveyor — they typically save 15–25% through proper specification and competitive tendering. (2) Buy materials in bulk when prices are favourable. (3) Use locally sourced materials where possible (granite, sand, timber). (4) Build in dry season to avoid weather delays. (5) Use a detailed Bill of Quantities — helps control variations. (6) Consider phased construction — build foundation now, wall to lintel level, then roof — spreading cash outflow.
