Starting without complete drawings is the most expensive mistake in Nigerian residential construction. Work begins on a sketch, decisions get made on site by whoever is present, and remedial work quietly consumes the contingency.
Underspending on the substructure is the second. Foundations are invisible in the finished house, which makes them the easiest place to economise and the most costly place to be wrong.
Others recur constantly: no soil investigation, no site drainage strategy, electrical and plumbing routes decided after walls are up, materials stored badly, and no single person accountable for quality.
