Building a single-storey house in Nigeria now costs about N34.83 million

A new estimate puts the cost of building a 161-square-metre single-storey house in Nigeria at about N34.83 million in 2026. The figure covers foundation, roofing, electrical work, a borehole and perimeter fence, but not land purchase.

The estimate was generated on September 9, 2026, for a property with a 161-square-metre ground-floor footprint built to a budget specification.

What the N34.83 million covers

Foundation work carries the biggest price tag at N7.37 million. This covers the substructure down to the damp-proof course and is based on a strip foundation suited to waterlogged soil.

Walling and the structural frame are projected at N5.35 million. Roofing and ceiling work, using 0.45mm aluminium longspan sheets and PVC ceiling boards, could cost around N4.22 million.

Finishes and services are estimated at N6.22 million. These include cement-screeded floors, standard paint, and basic electrical and plumbing installations. External works add another N1.98 million and cover a perimeter fence, borehole, generator house, overhead water tank and driveway.

The direct construction subtotal is N25.13 million. Indirect expenses push the total higher.

A 10% contingency buffer of N2.51 million is included to absorb unexpected costs. The contractor's profit margin, set at 15%, adds N4.15 million. Site oversight and supervision account for N1.93 million. Logistics and transportation add N1.11 million.

The total estimated cost comes to N34,826,897. Land purchase is not included.

Why the final cost can go higher

Several factors can move the actual cost above the estimate. Projects in Lagos, Abuja and Port Harcourt typically attract higher labour charges, dearer materials and steeper transportation costs compared to smaller towns.

Difficult soil conditions, such as waterlogged or weak ground, may require more robust foundation engineering. That adds to the overall bill.

Material choices are another major variable. Swapping basic finishes for premium tiles, POP ceilings, security doors and aluminium windows can take the total well beyond N34.83 million.

How homeowners can manage costs

Homeowners hoping to manage costs may benefit from sourcing materials directly from suppliers. Comparing prices before purchasing and releasing payments to workers only as each stage of construction is completed under proper supervision can also help.

Overall, a starting budget of around N35 million offers a realistic planning figure for a 161-square-metre single-storey home in Nigeria in 2026. The final cost will depend heavily on location, site conditions, labour rates and the quality of finishes chosen.
