Anyone who has gone around looking at homes knows this: we aren't really buying a home, we're buying a name. Raemian, Xi, Hillstate, Prugio. Same neighborhood, similar floor space, more or less the same concrete — and yet the price splits by hundreds of millions of won depending on which name is on the gate. Not the price of the brick and cement, but the price of the three syllables in front of them. It's a slightly strange arrangement, but we mostly accept it as natural.
The oligopolies so far — sugar, beer — were things that go into our mouths. This time it's the thing we go into and live inside: the home. And there is something odd about this market. Korea has tens of thousands of construction companies, yet the names that build the apartments we actually want to live in can be counted on one hand.
Tens of Thousands of Companies, Five Names
Look at the 2025 construction capacity rankings: more than 70,000 builders in Korea were assessed. Yet the top five seats have long been held by nearly the same faces. Samsung C&T is first for the twelfth straight year, with an assessed capacity of over 34 trillion won, followed by Hyundai E&C, Daewoo E&C, DL E&C, and GS E&C. The owners of the apartment brands we all know.
| Rank (2025 capacity assessment) | Company | Assessed amount | Flagship brand |
|---|
| 1 | Samsung C&T | 34.7219 trillion won | Raemian |
| 2 | Hyundai E&C | 17.2485 trillion won | Hillstate · THE H |
| 3 | Daewoo E&C | 11.8969 trillion won | Prugio |
| 4 | DL E&C | 11.2183 trillion won | e-Pyeonhansesang · Acro |
| 5 | GS E&C | 10.9454 trillion won | Xi |
The interesting part is that these five have a stage of their own where their power really shows: reconstruction and redevelopment — the so-called urban renewal business. In this prime market of tearing down aging neighborhoods and raising new apartments in their place, the ten largest builders won more than 48 trillion won of work in 2025, an all-time record. But even within that record, the tilt is severe. Hyundai E&C and Samsung C&T, just those two, took roughly 40% of the total, and the top five won more than three times as much as the five below them. On one side, trillion-won contracts pile up; on the other side are companies that couldn't land a single one. That is why people have started calling even urban renewal hyper-polarized.
The Wall Called a Name
Why do only a few names get to divide this prime cut? Because of the peculiar nature of the home as an object. For most people, a home is the single largest purchase of a lifetime. When you stake that much money, you choose the name that looks safest. A name that won't crumble for decades, that has few defects, that seems likely to hold up the price when you sell someday. A brand is, in the end, that long trust hardened into place, and that trust cannot be bought with money overnight. Add to it the relationships with reconstruction associations built over decades, and the financial strength to carry projects worth trillions of won, and there is almost no gap left for a new name to squeeze through.
So this wall works on us, the consumers, in a slightly wry way. We prop up the premium the wall created with, of all things, our own money. Raise an apartment of the same height on the same spot, and the market prices it differently depending on whether or not the name is Raemian. That difference didn't come from the concrete; it came from the name, and the name's premium is the toll this oligopoly collects. To live inside the wall, we pay the wall a premium.
The Home Is the Rampart
In the preface to this series, I wrote that everyone wants positioning — a rampart of their own. And the branded apartment may be the most visible form a rampart can take. In a society where which brand, which complex you live in reads like a station in life, buying that name is less like buying a home than like buying yourself a rampart. What the five builders are selling may not be concrete at all, but the nameplate on the rampart.
The scenery of 2025 shows the structure all the more clearly. Even as the property market froze and construction costs soared and the industry as a whole struggled, the reconstruction of Seoul's prime land kept flowing toward the five names. Nobody goes where building doesn't pay; everybody rushes where it does. The harder the market gets, the sharper the wall's outline becomes — because everything tilts toward the good sites and the good names.
The scoreboard says the same thing. In 2025, revenue fell at four of the five, but profit split decisively. Hyundai E&C swung back to the black, and GS E&C and DL E&C grew their profits by nearly half — while Daewoo E&C swung to a loss in the 800-billion-won range and Samsung C&T's construction profit was cut in half. A downturn doesn't make everyone equally poor; it sorts the gems from the stones.
The People Who Build the Names
The people who actually build these five names — under what terms do they work?
| Company | Employees | Average annual pay | Average tenure | Revenue per employee | Operating profit per employee |
|---|
| Samsung C&T (construction division) | 5,828 | company-wide 123.07 million won | 15.4 years | division 2.43 billion won | ~92 million won |
| Hyundai E&C | 6,900 | 117.49 million won | 13.8 years | separate 2.39 billion won | ~36 million won (returned to profit) |
| Daewoo E&C | 5,146 | 101.95 million won | 16.5 years | 1.39 billion won | ~ -180 million won (swung to loss) |
| DL E&C | 4,742 | 106.35 million won | 13.5 years | 1.00 billion won | ~48 million won (+42.8%) |
| GS E&C | 4,996 | 108.81 million won | 15.4 years | 1.62 billion won | ~96 million won (+53.1%) |
Basis: FY2025 (2025-12-31) annual report employee data. Samsung C&T shows construction-division headcount and division results (pay is the company-wide average); the rest are on a separate financial statement basis.
Pay hovers around 100 million won, tenure runs thirteen to sixteen years. Even in the year the property market froze, even in the year Daewoo E&C posted a loss in the 800-billion-won range, the terms at these five companies barely wavered. The wall of brand value that divides the prime reconstruction market props up, along with itself, the seats of the people working inside it. The per-employee operating profit column, though, is honest. On the same 100-million-won pay, at one company each person produces profit in the 90-million range, while at another each person shoulders a 180-million-won share of the loss.
The next story returns to the table. This time, a bowl of red broth — the thing we boil without thinking on rainy days. Ramen. How a name called Shin Ramyun became a national standard: we step into that fiery oligopoly.
