Towns Where Everyone Lives Under One Roof
Most people take for granted that a town means separate houses scattered along streets, each family behind its own front door. But scattered across the world, in places where weather turns brutal or isolation runs deep, entire communities have figured out how to compress everything into a single structure.
Schools, churches, grocery stores, police stations, and hundreds of apartments all share the same walls. The neighbors aren’t just next door.
They’re upstairs, downstairs, and down the hall. Privacy becomes negotiable.
Community becomes unavoidable.
Whittier, Alaska: The Town in a Tower
Sixty miles from Anchorage, tucked between mountains and the frigid waters of Prince William Sound, sits a town that barely looks like a town at all. Whittier, Alaska has about 272 residents, and nearly all of them live in a single 14-story building called Begich Towers.
The building started as military barracks during the Cold War. The U.S. Army needed a facility that could withstand brutal weather and potential attack.
When the military left, the residents who remained decided not to spread out across the harsh landscape. They consolidated instead.
Today, Begich Towers contains apartments, a post office, a small grocery store, a laundromat, a police station, a health clinic, a church in the basement, and even a bed and breakfast on the top floors. The school sits in a separate building directly behind the tower, connected by an underground tunnel so children never have to brave the elements between class and home.
Some residents own T-shirts that say “POW” — Prisoner of Whittier. It’s half joke, half truth.
Why Whittier Works This Way
The weather explains everything. Whittier receives an average of about 20 feet of snow annually.
Winter winds routinely hit 60 miles per hour. The town sits in one of the wettest spots in North America, averaging 197 inches of precipitation per year.
Getting to Whittier requires passing through the Anton Anderson Memorial Tunnel, a 2.5-mile passage that allows cars and trains to share the same bore. The tunnel closes at 10:30 every night.
Miss the last crossing, and you’re sleeping in your car at the entrance. Some residents have lived in Begich Towers for years without setting foot outside.
Everything they need exists within those concrete walls.
Life Inside the Building
Residents describe the experience in contradictory ways. For some, Begich Towers feels like an endless family reunion.
You know everyone. You see them in the hallways, in the laundry room, in the elevator.
Drama travels fast. One longtime resident keeps binoculars by her window, ostensibly for watching whales breach and mountain goats graze.
But she jokes they’re also useful for checking whether your husband made it to the bar.
For others, the closeness creates genuine community. Teachers can walk to work through a tunnel.
Doctors at the clinic live floors away from their patients. When supplies run low, neighbors share.
The building has developed its own informal economy and social structure, adapting to the constraints of its peculiar geography.
Fermont, Quebec: The Wall
Far north in Quebec, near the Labrador border, sits another town built for survival. Fermont was created in the early 1970s to house workers extracting iron ore from nearby Mont Wright.
The architects faced a problem: winter temperatures that plunge well below zero, combined with fierce sub-arctic winds that make being outdoors genuinely dangerous.
Their solution was a building 1.3 kilometers long and five stories tall, curved like a half-moon to block the prevailing north winds. Locals call it “Le Mur” — The Wall.
Everything Inside the Wall
The Wall contains 440 apartments. But it also contains a swimming pool, a shopping center, schools, a hotel, restaurants, bars, a skating rink, bowling alleys, a gym, a hospital, and the town hall.
During winter, which lasts about seven months, residents can go weeks without stepping outside. Everything they need exists within the massive structure.
Behind the Wall, protected from the wind, sit another 755 houses. The structure creates a microclimate, raising temperatures in its shadow and making life in those homes more bearable.
Wind tests during the planning phase showed the Wall could effectively protect about 600 houses, covering roughly two-thirds of the town’s residents.
The design was borrowed from Swedish architect Ralph Erskine, who built a similar windscreen in the arctic mining town of Svappavaara in 1962. But Fermont went further, integrating residential, commercial, and institutional functions into a single continuous structure rather than just housing.
The Mining Town That Architecture Built
Fermont exists because of iron ore, and the economy remains entirely dependent on mining operations. Over 80 percent of municipal revenues come from the industry.
The town’s population has fluctuated with commodity prices, dropping from peaks when the market faltered and recovering when demand returned.
The Wall stands as a monument to a particular era of architectural ambition. Planners in the 1970s believed they could engineer solutions to almost any problem, including the problem of making sub-arctic life comfortable.
Fermont represents that confidence made concrete. Whether it succeeded depends on who you ask.
The town has survived for over fifty years. Residents remain.
The mine keeps operating. But the isolated location and extreme conditions mean Fermont never quite became the thriving community its designers imagined.
Neft Dashlari: The City That Floats on Oil
Sixty miles off the coast of Azerbaijan, in the middle of the Caspian Sea, sits something that defies easy description. Neft Dashlari — “Oil Rocks” in Azerbaijani — is a tangle of drilling platforms, residential buildings, and rusting bridges spread across the water like a steel octopus.
Construction began in 1949 after Soviet geologists discovered massive oil deposits beneath the seabed. Workers sank old ships to create foundations, then built upward and outward.
By the 1970s, Neft Dashlari had become a genuine city, complete with apartment blocks, a cinema, a hospital, bakeries, parks with imported soil, and even a soccer pitch laid out on suspended metal platforms.
Living on the Water
At its peak in the 1960s, about 5,000 people lived and worked on Neft Dashlari. The city sprawled across more than 200 kilometers of roads and bridges connecting artificial islands.
Fresh drinking water arrived by tanker. Mail was delivered.
There were shops and cultural facilities and all the infrastructure of a real town, just balanced precariously above the waves.
The isolation was extreme. Workers spent weeks at a time on the platforms.
Getting to shore required a multi-hour boat ride. Weather could turn dangerous quickly, and the Caspian’s storms have claimed lives throughout the city’s history.
Yet for decades, people made homes there, raising families in an environment that existed nowhere else on Earth.
The Slow Collapse
After the Soviet Union dissolved, Neft Dashlari began its decline. Oil prices fluctuated.
Newer fields opened elsewhere. The infrastructure, never designed for permanence, started falling apart.
Today, only about 45 kilometers of the original 300 kilometers of roads remain usable. Sections of the city have literally collapsed into the sea.
Around 2,000 people still live and work there, extracting oil from a field that has produced over 170 million tons in its 75-year history. But much of Neft Dashlari now resembles a ghost town, its rusting structures slowly being reclaimed by the water.
The city that the Soviets once called the “eighth wonder of the world” has become a monument to both human ambition and entropy.
Kowloon Walled City: Density Beyond Imagination
Not all single-structure communities emerge from deliberate planning. Some grow organically, without architects or building codes, shaped only by necessity and the absence of authority.
The Kowloon Walled City in Hong Kong was demolished in 1994, but during its peak it housed approximately 33,000 people within 2.6 hectares — a population density of approximately 1.2 million per square kilometer. To put that in perspective, for Manhattan to achieve the same density, every person in Texas would need to move there.
How Chaos Organized Itself
The Walled City started as a Chinese military fort. When Britain leased Hong Kong in 1898, they carved out an exception for this small enclave, which remained technically under Chinese jurisdiction.
Neither government truly controlled it. Refugees fleeing the Chinese Civil War flooded in after World War II, building shacks on top of shacks, apartments on top of apartments, until the entire structure rose 14 stories and merged into a single interconnected mass.
Buildings were constructed directly onto neighboring buildings. Residents punched through walls to use their neighbors’ staircases.
Electricity came through illegal connections. Water arrived via a network of pipes that residents installed themselves, threading through the structure in patterns that only made sense to those who built them.
Order in Darkness
Sunlight never reached most of the interior. The alleys between buildings were so narrow and overhung that residents lived in permanent twilight.
Garbage fell from above since there was no collection service. The Triads controlled much of the activity, running gambling operations and other businesses.
But the Walled City also contained kindergartens, doctors’ offices, and factories producing everything from fish paste to metal parts. Mail was delivered.
Neighbors settled disputes through informal councils. The density created problems, but it also created a community that functioned according to its own logic.
Architect Aaron Tan, who studied the structure as it was being demolished, described being humbled by how residents had solved problems in ways that trained designers never would have imagined.
Arcosanti: The Experiment That Never Finished
In the Arizona desert, about 70 miles north of Phoenix, sits an incomplete monument to a different kind of thinking about community. Arcosanti was designed by architect Paolo Soleri as a demonstration of what he called “arcology” — the fusion of architecture and ecology into self-contained, hyperdense urban environments.
Construction began in 1970. The plan called for housing 5,000 people in a structure that would leave the surrounding landscape untouched.
Residents would live, work, and socialize within a single integrated complex, minimizing resource consumption and maximizing community interaction.
The Dream and the Reality
More than fifty years later, Arcosanti remains only about five percent complete. The community houses around 40 to 50 full-time, year-round residents, with the number swelling to as many as 80 during workshop periods.
The community supports itself partly through tourism and partly by selling bronze bells cast on-site. The structure remains a fraction of its intended scale.
Visitors describe the place as feeling less like a city and more like a sculpture slowly growing from the desert floor. The buildings that exist demonstrate Soleri’s aesthetic — curved concrete forms that seem to emerge organically from the landscape.
But the grand vision of a self-sufficient urban alternative remains unrealized.
Arcosanti functions as a laboratory rather than a model. It shows what might be possible if enough people committed to radically different ways of living together.
Whether that possibility represents the future or just an interesting detour remains unclear.
McMurdo Station: The Antarctic Exception
On Ross Island in Antarctica, the largest community on the continent operates year-round. McMurdo Station is not technically a town, but it functions like one.
At peak population during summer, between 1,000 and 1,200 people live there. Winter brings the number down to around 150 to 200.
The station includes dormitories, laboratories, a fire station, power plants, a harbor, airfields, and various support facilities. Residents work in close quarters under extreme conditions.
The sun disappears entirely for months during winter. Temperatures regularly drop below -40 degrees.
Going outside requires careful preparation.
Isolated Together
Life at McMurdo creates intensity. People eat together, work together, and socialize together because there are no alternatives.
Relationships form quickly. Conflicts escalate easily.
The community develops its own rituals and inside jokes, shaped by the unique circumstances of Antarctic isolation.
The station functions as a kind of accidental arcology — a self-contained human habitat in an environment hostile to human life. It proves that people can live together in extreme density and isolation when circumstances demand it.
Whether they enjoy it varies considerably from person to person.
The Line: A Future That Keeps Getting Smaller
Saudi Arabia announced plans in 2021 for a linear city called The Line — a 170-kilometer structure in the desert that would house 9 million people in a building 200 meters wide and 500 meters tall. No cars, no streets, no carbon emissions.
Everything connected by high-speed transit running the length of the structure.
By 2024, the project had been dramatically scaled back. Reports indicated the initial phase would stretch just 2.4 kilometers rather than the full 170, housing fewer than 300,000 residents by 2030 rather than the originally projected 1.5 million.
By late 2025, after an estimated $50 billion had been spent, reports emerged that construction had been suspended entirely. The vision of a city that was itself a single building encountered the same problems that have plagued such projects throughout history: cost, complexity, and the gap between architectural ambition and engineering reality.
Why These Places Matter
The towns that have actually managed to house their populations under single roofs share common characteristics. They exist in extreme environments where spreading out is dangerous or impractical.
They emerged from specific economic needs — military bases, mining operations, oil extraction. They trade privacy for protection, independence for community.
Some residents love this arrangement. Others endure it as a necessary compromise.
But all of them demonstrate something about human adaptability. When circumstances demand it, people figure out how to live in configurations that would seem impossible under normal conditions.
The buildings may look strange from the outside. From the inside, they’re just home.
What the Walls Reveal
For more than a century, architects have been fascinated by the idea of a city inside a building. Le Corbusier envisioned towers with all the necessities for locals.
Domed cities that could produce their own weather were Buckminster Fuller’s idea. Megastructures that house millions of people are common in science fiction.
The reality has turned out to be smaller and more peculiar. Rather than being utopian experiments, places where people actually live under one roof are typically practical solutions to particular issues.
Alaskan weather makes any other arrangement miserable, which is why Whittier works. Fermont operates because the town would otherwise be uninhabitable due to sub-arctic winds.
Because there were no other options due to the Caspian Sea, Neft Dashlari was successful.
These communities do not demonstrate that this is how everyone should live. They demonstrate that certain individuals can, under certain conditions.
They are surrounded by walls that do more than just block out the weather. For better or worse, they produce unusually intense social environments.
Life continues on the inside. Neighbors quarrel and support one another.
Kids attend school. Adults leave for work.
The everyday activities of life go on, but they are crammed into areas that serve as a constant reminder to everyone that they are all in this together.
