12 Proven Ways to Reduce Your Building Cost in Nigeria

By My House Cost NG · Updated 15 October 2026 · 3 min read

Savings below are calculated for a standard 5-bedroom duplex + BQ in Lekki costing ₦113.4M.

  1. Use interlocking blocks — saves about ₦7.3M on mortar and plaster.
  2. Use laterite blocks — saves about ₦3.3M where good laterite is available.
  3. Choose PVC ceilings instead of POP — saves about ₦0.7M.
  4. Basic finishes now, upgrade later — saves about ₦20.8M.
  5. Stick with aluminium roofing — stone-coated would add about ₦1.1M.
  6. Skip the BQ for now — saves about ₦17.8M; you can add it later.
  7. Buy cement and rods in bulk during price dips (see the price tracker).
  8. Build in phases and roof early.
  9. Get a BOQ before you start so quantities can't be inflated.
  10. Pay labour per task (per block laid, per m² plastered), not per day.
  11. Keep the design simple — every extra corner adds formwork and roof complexity.
  12. Supervise materials on site to prevent waste and theft.
