The Psychology of Sunk Cost in Nigerian Building Projects

The most expensive thing in the Nigerian construction industry is not cement. It is not granite, nor is it the cost of land in Banana Island.

The most expensive thing is the inability to admit a mistake.

There is a specific tragedy we see often at Danforce. A client living in Houston or London contacts us about a project in Benin City or Lagos. They have already spent N50 million. The structure is at the lintel level. But there is a problem. Maybe the land is in a government acquisition zone. Maybe the foundation was done by a “family engineer” who used 30% less cement than required, and the walls are already cracking.

The rational move is obvious: Stop. Cut the loss. Demolish the defect or abandon the land.

But the client rarely does this. Instead, they say, “I have already put N50 million into this. I cannot just walk away. We have to finish it.”

This is the Sunk Cost Fallacy. In economics, it is a known error. In Nigerian real estate, it is a financial suicide pact.

The Two Ledgers

The problem arises because the builder keeps two sets of books.

The first is the Market Ledger. This is reality. It asks: What is this structure worth right now? If the foundation is cracked, the value is zero (or negative, because you have to pay to clear the rubble).

The second is the Emotional Ledger. This is fantasy. It asks: How much pain did I suffer to get here? It adds up every wire transfer, every argument with family members, every sleepless night. The client looks at the crumbling walls and sees N50 million of “effort.”

They believe that by spending more money, they can validate the past money. They think if they just put a roof on the cracked walls, the N50 million is “saved.”

It is not. The N50 million is gone. It was incinerated the moment it was spent on bad work. Spending another N20 million to roof a defective house doesn’t save the first N50 million; it just endangers the next N20 million.

The “Manage It” Trap

This psychology is weaponized by a specific phrase in Nigerian pidgin: “We go manage am.”

When a contractor realizes he has made a mistake—perhaps the column is crooked or the room dimensions are wrong—he appeals to your sunk cost. He knows you don’t want to tear it down. So he suggests a hack. He will plaster over the crooked column. He will use a ” wedge” to straighten the door frame.

He is selling you relief. He is telling you that you don’t have to face the loss.

But gravity cannot be managed. Water cannot be managed. If you “manage” a structural defect to save face today, you are scheduling a collapse for five years from now. The house does not care about your feelings or your budget history. It only cares about physics.

The Freedom of Zero

The only way to build successfully in Nigeria, especially from abroad, is to be ruthless about the present.

You must look at your project every morning and ask: “If I had not started this, would I buy this incomplete structure for what I have spent on it?”

If the answer is no, you are in a trap.

We recently advised a client to abandon a N15 million foundation because it sat on a floodplain that would require N40 million in drainage to fix. He was horrified. He felt he was “losing” N15 million.

We reframed it: By walking away, he was saving the N40 million he was about to waste. He eventually moved to a dry plot. Today, he has a completed house. If he had stayed, he would still be fighting the water, throwing good money after bad.

Realizing that your past spend is irrelevant is painful. It feels like burning cash. But in construction, the only thing worse than starting over is finishing a mistake.

Frequently Asked Questions

Since we began auditing stalled projects for diaspora clients, we have seen the same hesitation to “pull the plug.” Here are the questions we hear when we deliver the hard news.

1. My uncle supervised the bad foundation. If I demolish it, won’t it cause a family war? It might. But you have to choose your war. Do you want a conflict with your uncle now, or a conflict with gravity later? If the house collapses or cracks irreparably, you will lose the money and the relationship anyway. It is better to blame the “strict professional engineer” (us) and save your capital.

2. Can’t we just reinforce a weak structure instead of demolishing it? Sometimes, yes. . We can do “retrofitting”—adding steel columns or concrete jacketing. But this is expensive. Often, it costs more to retrofit a bad bungalow than to knock it down and rebuild it properly. We only recommend this if the cost of demolition is astronomical.

3. I bought land that turned out to be under government acquisition. Should I build quickly to “secure” it? This is the most dangerous myth in Lagos and Benin. People think, “If I build a roof, the government won’t demolish it.” This is false. The government demolishes fully built mansions every year. If you build on committed land, you are just increasing the value of the pile of rubble the bulldozers will leave behind.

4. How do I know if I’m in a sunk cost trap? Ask for an “As-Is Valuation.” If the cost to complete the house plus the cost to fix the errors is higher than the final market value of the house, you are in a trap. You are building an asset that will immediately be worth less than you paid for it.

5. Is it ever okay to abandon a project temporarily? Yes, but you must “mothball” it. Don’t just walk away. Cap the iron rods so they don’t rust. Seal the tops of the block work. If you leave it exposed to the rain for three years, the sunk cost fallacy kicks in again—you will try to continue building on rot.

The hardest check to write is the one that admits you were wrong. But it is also the cheapest check you will write in the long run.
