Cost of Building a 3 Bedroom Flat in Nigeria (2026)

Planning your own home? Discover the actual cost of building a 3 bedroom flat in Nigeria in 2026, with realistic price breakdowns for every stage.

Published November 2026 · Skills · by Skillnaija Team

Planning your dream home is exciting, but knowing the realistic cost of building a 3 bedroom flat in Nigeria in 2026 is critical before digging any foundation. With fluctuating building material prices, currency adjustments, and labour variations across states, underestimating your budget can easily cause your project to stall midway.

Whether you want to build a standard family bungalow in Ibadan, an executive flat in Asaba, or an off-plan rental unit in Ogun State, having an itemised budget saves you from costly surprises. This comprehensive guide breaks down the true cost of materials, artisan wages, professional fees, and finishing expenses required to complete a 3-bedroom apartment from start to finish.

Overview: Estimated Total Cost in 2026

In 2026, building an all-ensuite 3-bedroom bungalow or ground-floor flat in Nigeria typically falls into three finishing tiers:

• Basic Finishing: ₦14,000,000 to ₦19,000,000 (standard locally manufactured tiles, regular sanitary fittings, simple long-span aluminium roof, painted walls).
• Standard / Modern Finishing: ₦20,000,000 to ₦28,000,000 (quality vitrified or porcelain tiles, POP ceilings across all rooms, stone-coated roofing sheets, casement windows, perimeter fence with gate).
• Luxury Finishing: ₦30,000,000 and above (smart electrical installations, high-end Italian porcelain, granite kitchen countertops, security burglary systems, and solar setups).

Note: These figures assume you already own the land. Land purchase, title perfection (such as Governor's Consent or C of O), and state agency building plan approvals are separate costs.

Stage 1: Pre-Construction and Substructure (Foundation)

The substructure carries the weight of the entire building. The nature of your soil determines whether you need a simple strip foundation or a reinforced raft foundation (common in marshy regions like Lekki or parts of Port Harcourt).

1. Setting Out and Excavation

Clearing a 50x100ft plot, profiling, pegging, and manual trench digging by labourers costs between ₦180,000 and ₦300,000 depending on soil hardness and location.

2. Blinding and Foundation Footing

Pouring a lean concrete mix (blinding) in the excavated trenches stabilises the base. For a typical 3-bedroom flat, concrete pouring and iron rod reinforcement at this stage take approximately 15 to 20 bags of cement, 1 tipper of sharp sand, and 1 tipper of 1/2-inch granite, totalling around ₦550,000 to ₦800,000.

3. Foundation Blockwork

A standard 3-bedroom footprint requires about 800 to 1,100 pieces of 9-inch vibrated sandcrete blocks laid from trench bottom to damp-proof course (DPC) level. Filling these hollow blocks with concrete grout strengthens them against moisture and load pressure.

4. Backfilling, Compaction, and DPC Casting (German Floor)

You will need roughly 3 to 6 trips of red laterite filling sand, thoroughly rammed and watered. Casting the German floor requires approximately 30 to 45 bags of cement, wire mesh or iron rods (BRC mesh), damp-proof membrane (nylon), sharp sand, and granite aggregate.

Estimated Foundation Subtotal: ₦3,800,000 – ₦5,500,000.

Stage 2: Superstructure (Blockwork, Lintel, and Beams)

The superstructure represents the visible walls rising from the German floor up to roof level. Accuracy and block quality are paramount here to avoid future wall cracks.

• Wall Blocks: A 3-bedroom flat typically needs between 2,200 and 2,800 units of 6-inch or 9-inch sandcrete blocks.
• Lintels and Columns: Reinforcement bars (10mm, 12mm, and 16mm TMT rebars), stirrup binding wire, and marine or softwood formwork for lintel beams above windows and doors.
• Masonry and Labour: Bricklayers charge either per block laid (₦100 to ₦160 per block) or work on daily wages with mortar mixers.

Estimated Superstructure Subtotal: ₦2,700,000 – ₦3,900,000.

Stage 3: Roofing the 3 Bedroom Flat

Roofing protects your investment. In Nigeria, roof style (gable, hip, or parapet flat roof) and sheet type heavily dictate this expense.

Roofing Carcass (Woodwork)

Hardwood timber (2x3, 2x4, 2x6, and fascia boards) treated with anti-termite chemicals, together with roofing nails and wall-plate hold-downs, will cost between ₦1,400,000 and ₦2,100,000 including carpenter fees.

Covering Materials

Homebuilders generally choose between two popular options:

1. Long-Span Aluminium (0.45mm – 0.55mm): Clean, durable, and cost-effective. Materials and professional fixing run between ₦1,600,000 and ₦2,400,000.
2. Stone-Coated Metal Shingles (Gerard / Bond): Elegant and noise-dampening, costing between ₦2,800,000 and ₦4,500,000 depending on quality (original gauge vs light imports).

Estimated Roofing Subtotal: ₦3,200,000 – ₦5,500,000.

Stage 4: Plastering, Ceilings, and Electrical/Plumbing Rough-In

Once the roof is on, your house enters the carcass stage, ready for first-fix piping and plastering.

• Plastering (Rendering): Internal and external wall plastering consumes about 70 to 95 bags of cement plus plaster sand, running about ₦1,300,000 to ₦1,800,000 in materials and masonry labour.
• Electrical Rough-In: Conduit PVC piping, distribution boards, wall knock-out boxes, and earthing installation costs roughly ₦450,000 to ₦700,000.
• Plumbing Rough-In: PVC drain pipes, PPR water supply lines, soakaway pit construction, and septic inspection chambers cost about ₦800,000 to ₦1,300,000.
• Ceiling Finishes: Plaster of Paris (POP) designs across all three bedrooms, living room, and kitchen cost between ₦1,100,000 and ₦1,800,000. Simple PVC tongue-and-groove ceilings offer a cheaper alternative around ₦550,000.

Stage 5: Finishing (Tiles, Doors, Windows, Painting, and Sanitary Wares)

Finishing is where costs easily escalate if left unmonitored. It defines the comfort, visual appeal, and durability of your house.

Windows and Exterior Security Doors

Glazed aluminium sliding windows or modern casement frames with built-in burglar bars for about 12 window openings cost between ₦900,000 and ₦1,600,000. Turkish or high-grade steel security doors for front and back access run around ₦350,000 to ₦700,000 total.

Floor and Wall Tiling

A 3-bedroom flat has roughly 140 to 180 square metres of floor space, plus wet-wall tiling for three bathrooms and the kitchen. Purchasing 60x60 porcelain tiles or 40x40 ceramic tiles alongside adhesive cement and grouting amounts to ₦1,400,000 to ₦2,600,000.

Sanitary Fittings, Interior Doors, and Painting

Water closets (WCs), wash basins, kitchen sinks, shower sets, interior wooden flush doors, and three coats of emulsion/satin paint require an additional ₦1,800,000 to ₦3,200,000.

Estimated Finishing Subtotal: ₦4,500,000 – ₦8,100,000.

How to Fund Your Building Project in Nigeria

Very few working-class Nigerians build with an upfront lump sum. Most employ a milestone approach: buying blocks this quarter, casting the German floor next, and pausing before tackling the roof. Many professionals build their dream homes by adding foreign exchange earnings or freelance income to their salary.

Smart Ways to Cut Construction Costs Without Compromising Quality

"The most expensive mistake in Nigerian building projects is buying substandard sandcrete blocks that crumble after the first rainy season."

• Mould Blocks On-Site: If your plot is secure and has accessible water, buying bags of cement and hiring a commercial manual block-moulding operator often saves 15% to 20% compared to purchasing from commercial block yards.
• Buy Materials in Bulk: Sourcing granite, sand, and cement by the trailer load directly from regional distributors cuts retail markups significantly.
• Supervise Directly or Hire Trusted Eyes: Artisan material diversion is a common cause of blown budgets. Unannounced site visits keep wastage low.
• Adopt a Functional Floor Plan: Complex architectural roof shapes, multiple parapets, and unnecessary alcoves inflate carpenter labour and sheet requirements by up to 25%.

Frequently asked questions

How long does it take to build a 3 bedroom flat in Nigeria?

With steady financing and an experienced builder, a standard 3-bedroom bungalow can be erected and finished in 3 to 6 months. When funding the project stage-by-stage out of pocket, most Nigerians complete the process over 1 to 3 years.

Can 10 million Naira build a 3 bedroom flat in Nigeria in 2026?

₦10 million can comfortably bring a 3-bedroom flat to the roofing or lintel stage, but it is insufficient to complete the full project to move-in standard given current material and artisan costs in 2026. A realistic minimum for full basic completion is around ₦14 to ₦16 million.

How many blocks are needed for a standard 3 bedroom flat in Nigeria?

A standard 3-bedroom flat requires approximately 3,000 to 4,000 sandcrete blocks (both 9-inch and 6-inch) for the foundation and superstructure walls combined, depending on ceiling height and the number of partition walls.

Which is cheaper between a 3-bedroom bungalow and a 3-bedroom block of flats?

A standalone 3-bedroom bungalow is significantly cheaper to build than a block of flats. Multi-storey units require heavy structural decking, reinforced columns, specialised engineering supervision, and deeper foundation footings that sharply increase the initial capital required.
