Renovating an 18-Hole Golf Course: The Bill Has Doubled, and Public Courses Pay the Heaviest Price

An automatic irrigation system for 18 holes. In 2026, the quote was 1.5 million USD. In 2026, with identical specifications, identical acreage, identical sprinkler heads and valves, the invoice came to 4.5 million USD. Three times over five years. Water did not get more expensive. PVC did not become scarce. The entire supply chain of materials and specialist labour in golf course construction has shifted to a new price floor, and that floor is spreading from elite private clubs down to the municipal courses with no budget to follow.

The budget for renovating an 18-hole course sat at 10-12 million USD before 2026. Today, 20-30 million USD is common. Divide both ends by 18: cost per hole has climbed from roughly 555,000-667,000 USD to 1.1-1.67 million USD. A 100-150% increase inside a short cycle, while consumer price indices across most developed markets rose less than 25% over the same window.

To be clear: most golf courses in the world are not in the 30 million USD bracket. That group is a minority. But that minority is setting the price for the entire market, and that is the variable worth analysing.

Why I read construction cost sheets

I came to this problem from an unexpected direction: football. In 2026, while studying International Communication in Binh Duong, I built an xG model in Excel to analyse 26 rounds of V.League. I started a blog from a lecture hall, believing data would speak for itself. Eleven years later, I taught it to speak in sentences. My trade is turning invisible things, chance quality, pressing intensity, the value of a run into space, into measures that can be compared.

Golf course economics runs on the same principle. Everyone feels that everything has become more expensive. Feeling cannot build a comparison table, and it cannot answer the important question: more expensive for whom, and in which line item.

This is a problem of units. Cost per hole. Cost per round the course actually serves in a year. Cost per member. Without normalising to units, people can only argue with sensations.

My sample covers roughly 24 renovation projects across three tiers: elite private clubs, second-tier city clubs, and municipal or public courses. The sample is small. Three variables I cannot control and must state: exchange rates and freight costs on imported materials; local rules on irrigation water sources; and ownership structure, private versus public operation. Those three can skew results by 15-20%. I accept that error margin and attach it to every conclusion rather than rounding it away for a cleaner story.

And here is the biggest blind spot. In football I have xG, PPDA, ball circulation speed, measures standardised across thousands of matches. In golf, no equivalent exists for a golf hole. No index answers the question of how much better an experience 30 million USD buys. When value cannot be measured, people measure price instead. That is why a cost sheet becomes the most important document in this industry.

Irrigation: one price list, two fates

Irrigation is the clearest example of how regressive renovation costs are. The same absolute increase lands with completely different relative weight depending on budget size.

For an elite club with a 25 million USD budget, a 4.5 million USD irrigation package is 18% of the project. For a public course with a 5 million USD budget, the same package is 90%. One quote sheet, two incomparable outcomes. The elite club reads it as a line in a spreadsheet. The public course reads it as the entire project, and usually concludes the project does not exist.

There is no escape by buying the cheaper option. Sprinkler heads, valves, central controllers, signal wiring, pumps: the global supplier list for this category holds a handful of names, and they price on the same frame for every client in every market. This is the point emerging-market policymakers routinely miss. Material prices are not a local variable. You can pay maintenance staff at Vietnamese wage levels. You cannot buy an irrigation controller at Vietnamese price levels.

The result is a form of technical inequity: two courses in countries with different living standards, same acreage, same water requirement, receive almost identical invoices. The course in the lower-income market must divert a far larger share of revenue to buy the same equipment. Across the 24 projects I reviewed, this was the single largest reason projects were cut in scope.

Architect supply: a market that cannot expand

Golf course architecture is a market with a near-fixed supply. The number of individuals worldwide with enough standing to sign a major renovation sits in the dozens. Keith Foster is in that group, and his schedule is booked three years out.

A three-year backlog means the opportunity cost of time is priced in. When demand outruns supply in a market that cannot scale quickly, and nobody trains a top-tier golf architect in two years, rising fees are arithmetic, not personal greed. The downstream effect is the worrying part: when a design office takes on too many projects at once, detailed work is delegated downward. The client pays more for a name while the name's own hours on the drawings shrink.

I hold this hypothesis at low confidence, because I have no internal data on staffing allocation inside design firms. But it is the kind of risk no fee proposal ever shows. You buy a brand; you receive a product finished by someone else.

One secondary consequence is worth noting: the boom era the trade calls golf architecture's roaring twenties cannot run forever. A three-year backlog is the signature of a cycle peak, not of a new equilibrium. Insiders themselves have begun speaking about sustainability.

The ratchet effect: one club renovates, the whole market resets

The transmission mechanism is almost too simple. One club upgrades, and a new standard is established. The problem is not that the club spends its own money; it has every right to. The problem is how the market reads that act, as a new definition of what counts as a proper course.

I have seen this exact mechanism elsewhere. The transfer market is full of names paid for their past. I make a living reading the future. When one club pays 40 million USD for a player off a single good season, rivals do not re-examine their model. They reprice the entire cohort. Golf courses behave identically. One club spends 25 million USD on landscaping and amenities, and next season a second-tier board must explain why its course falls short of standard.

The danger is that the standard is not measured by playing quality. It is measured by what can be photographed, placed in a brochure and presented at a members meeting. A correctly engineered drainage system produces no photographs. A new clubhouse produces a great many.

The second tier: squeezed between two price levels

Second-tier city clubs are trapped hardest. They lack elite budgets but carry elite social pressure. The result is a predictable half-investment: build the visible layer, the landscaping, the clubhouse, the floodlights, and defer the invisible layer, the drainage, the soil profile, the turf structure.

Across the 24 projects I reviewed, a substantial share fits this pattern. This is the kind of decision that surfaces five years later as faster-than-expected deterioration, by which point nobody remembers it was made in a budget meeting. Cost does not disappear. It moves from the investment column to the remediation column.

Technically it is a clear mistake. Internally, politically, it is rational: nobody is fired for building a handsome clubhouse. Plenty are fired for spending a million dollars on drainage nobody can see.

Public courses: when one spreadsheet line becomes the whole budget

Public courses have no options. They share the same materials price list as elite clubs, but their budgets come from public funds and compete with schools, hospitals and roads. A project to replace irrigation that consumes 90% of an annual budget is no longer a technical project. It is a political argument, and the outcome is almost always deferral.

Defer one year. Then three. Then ten. In the interim the old system keeps leaking, pumping electricity costs climb, turf quality falls, and the course steadily loses its ability to serve the very players it was built for.

I once wrote about Germany's collapse before a major tournament. Not because I was clever, only because I did not believe the myth. Same here. The current myth is that golf is booming. The data does not deny growth; it shows growth concentrated among high spenders while the infrastructure serving ordinary players is pushed out of reach. Numbers do not lie. Reputation whispers into the ear of anyone who does not read the table.

Cost per round, and Vietnam's particular structure

This is the part I consider most valuable, and the part almost nobody does.

A club spends 25 million USD on renovation, amortised over 15 years: 1.67 million USD a year in capital alone. If that course hosts 30,000 rounds a year, capital cost per round is about 56 USD. Before 2026, a 10 million USD project at the same round volume worked out to about 22 USD. Capital cost per round has risen nearly 2.5 times in a single project generation.

At 45,000 rounds a year, the new figure drops to about 37 USD per round, still 68% above the old level. This is why round volume becomes the survival variable: once the money is spent, the only way to lower unit cost is to sell more rounds. But selling more rounds degrades the experience, and the spiral begins.

In Vietnam the structure carries an extra variable. Most domestic courses operate a membership model tied to real estate: the course's value sits not in green fee revenue but in the land value around it. The payback calculation is therefore not measured in rounds sold.

Short term, that is an advantage. A developer can spend 30 million USD on renovation without proving a matching green fee increase, provided nearby land values rise. Structurally, though, it produces an uncomfortable result: when a course's value is anchored to land, course quality becomes a secondary variable. And when the property cycle turns, maintenance cash flow is the first to be cut, ahead of staffing and ahead of marketing.

I hate uncertainty. But 2026 taught me that an unforeseen variable can outweigh every algorithm. When stadiums emptied during the pandemic, home win rates in V.League fell from 49% to 38%. Home advantage came from the crowd, not the pitch. Empty stadiums in 2026 made me ask whether home advantage comes from the ground or the spectators. The data has an answer. The same lesson applies here: much of what we call the value of a golf course is really the value of what surrounds it. When the surroundings vanish, a course is a field of grass with an expensive irrigation system.

Probabilities instead of sentiment

Risk of a second-tier club borrowing to renovate everything at once: high level, medium probability, high impact. Risk that public courses cannot access modern irrigation within seven years: high level, high probability, medium impact. Risk that a burst bubble leaves sunk costs behind: medium level, low-to-medium probability, high impact. Risk that the new price floor becomes permanent: medium probability, high impact.

And one risk rarely mentioned: interest rates. If rates stay high, every debt-financed renovation becomes a quarterly cash flow pressure rather than a one-off investment. In my model this is the variable capable of pushing the second tier's default probability to 25-30% over three years, conditional on flat round volume. That condition matters enormously: at 15% annual round growth, the probability falls below 10%. I do not hide my assumptions behind a single verdict.

The counterintuitive angle: correlation is not causation

Rising renovation costs do not prove course quality is falling. The opposite may be true: courses spending 30 million USD now have better playing surfaces than at any point in history. The problem is not absolute quality. It is the gap between tiers.

When I speak of risk, I am not saying elite courses will collapse. I am saying the probability that a public course in an emerging market gains access to a modern irrigation system within seven years sits below 40%. That estimate comes from budget structure, not market forecasting. Small sample, stated assumptions, and I am willing to be proven wrong by better data.

The next counterintuitive point: the assumption that pushing public courses out will shrink the golfing population may be wrong. In football I once believed losing an academy would degrade league quality a decade later. Structurally that holds. In practice, playing talent can arrive from other markets and the league keeps running. In golf, players squeezed off grass can move to driving ranges, indoor simulators, or leave the sport entirely. Nobody has data good enough to say which path dominates. And with no data, people default to assuming they leave. That is a sentiment dressed up as a technical conclusion.

The third and most important point: golf's infrastructure investment model is repeating the exact error of young-player valuation models, overrating what is visible and sellable, underrating what operates quietly. A well-engineered drainage system photographs badly. A new clubhouse photographs beautifully. In football that is the locker-room chemistry story, absent from every index until the day it disappears and a team collapses with no explanation. In golf, locker-room chemistry is the soil profile, the drainage, the turf structure at the lowest cutting height. Nobody votes for it in a board meeting.

And one alternative reading I am obliged to state: this may not be a bubble. It may be a permanent repricing. If materials, specialist labour and design supply all stay tight, the old price level does not return. The question then stops being whether to wait for the bubble to deflate and becomes how to redesign the financial model of a mid-tier course. I split the probability roughly evenly: 45% that the price floor corrects within 24 months, 55% that the new floor holds and becomes the standard.

That is why I do not predict. I read the data and accept the consequences.

Signals for the next cycle

Three signals worth tracking, ranked by predictive value.

Irrigation cost per hole. If quotes for premium specification hold above 4 million USD per 18-hole course for four consecutive quarters, the regressive burden on public courses is confirmed structurally rather than as a temporary spike.

Architect booking lead time. When it falls from 36 months to under 18, demand has cooled. In previous construction cycles this indicator led actual investment decline by roughly 12-18 months. It is the earliest and easiest signal to observe.

Public course deferral announcements. Hard to collect, scattered, no central database. But the highest predictive value, because it directly measures exclusion.

Plan B for the second tier, if the data warns correctly: phase renovation instead of doing it at once; buy materials in multi-course groups to gain negotiating power; standardise specifications to widen the supplier list; and accept an irrigation system that is good enough rather than best in class. The risk in Plan B is not technical. It is that it produces no marketing story, and in this industry, without a marketing story it is hard to sell memberships. That is the real breaking point, not the pipework.

A golf course does not need a 4.5 million USD irrigation system to be better for players. That 4.5 million is buying something else: posture. When the industry learns to price posture separately from pricing turf, the game changes. Until then, the only thing I can do is count, and record enough detail that nobody can later claim nobody warned them.
