Cost Estimator: How Much to Build a House

New Home Construction Cost Estimator

A practical, friendly guide and quick calculator to estimate how much it will cost to build a new home in Nigeria. Get per‑sqm rates, a step‑by‑step budget plan, and money-saving tips.

Why use a construction cost estimator?

Before you break ground, an accurate cost estimate helps you set a realistic budget, secure financing, compare contractor quotes, and avoid costly surprises. This guide focuses on the main cost drivers—land, foundation, structure, finishes, services (electrical/plumbing), and soft costs (design, permits, contingency)—so you can make confident decisions.

Quick cost snapshot (example estimates)

Note: these sample rates are illustrative. Replace with local quotes for precise budgeting.

Quality Level	Estimated Cost per m² (NGN)	Notes
Budget/Basic	₦120,000 — ₦180,000	Simple finishes, local materials
Medium/Standard	₦180,000 — ₦280,000	Good finishes, some imported fixtures
High-End	₦280,000 — ₦450,000+	Premium finishes, high-spec MEP systems

To estimate total cost: multiply the chosen per‑m² rate by your house's gross floor area (GFA) in square metres, then add land costs and soft costs (design fees, permits, contingency).

Tip: set contingency to at least 10–15% for exchange rate or material-price volatility.

How the estimator works

The calculator multiplies the chosen cost-per-m² by your gross floor area to estimate construction cost (structural, finishes, MEP). Then it adds soft costs (architect/engineer fees, approvals) and land cost to give a project total. This quick method is ideal for early budgeting—detailed quantity surveys are still required for contractor tendering.

Detailed cost breakdown (what to budget for)

• Land acquisition: Purchase price, survey, deed registration.
• Professional fees: Architect, structural engineer, project manager (usually 6–12% combined of construction cost).
• Permits & approvals: Planning permits, building permit, environmental clearance, connection fees.
• Site works & foundation: Excavation, soil treatment, piling (if required).
• Structure & shell: Concrete, masonry, roof structure.
• MEP (Mechanical, Electrical, Plumbing): Wiring, plumbing, HVAC or ventilation, water supply and sewage.
• Finishes & fixtures: Flooring, doors, windows, paint, sanitaryware.
• External works: Fencing, driveway, landscaping.
• Contingency: 10–20% recommended.

Action plan — 7 steps to move from estimate to build

1. Confirm site and obtain land documents.
2. Commission schematic design and a rough cost plan.
3. Refine design and request detailed contractor bids (use quantity surveyor if needed).
4. Secure permits and utility connection approvals before construction starts.
5. Appoint a contractor with clear payment milestones and a signed contract.
6. Monitor progress and cashflow; keep contingency funds available.
7. Complete handover, snagging, and final certification.

Money-saving tips

• Standardise dimensions to reduce waste and offcuts.
• Buy materials in bulk and negotiate with trusted suppliers.
• Use local materials where it doesn’t compromise durability.
• Stage works strategically to avoid mid-project expensive changes.
