On an ordinary afternoon in Tempe, Arizona, Sheryl Murdock steps out of her apartment onto a narrow, shaded pathway. No engines rumble. No exhaust clouds the air. Instead, she hears the clink of glasses, the murmur of conversation, and the soft thud of a cornhole game echoing across a central plaza. White-washed buildings frame her view, their walls catching the desert sun. Magenta bougainvillea spills over doorways. Fairy lights crisscross overhead. She stands in Culdesac, the United States’ first purpose-built car-free neighbourhood—and to her, it feels less like Arizona and more like stepping into a Greek village.
The Mediterranean Dream Made Real
When architect Daniel Parolek designed Culdesac, he wasn’t thinking of typical American suburbs. His inspiration came from wandering the hillside towns and coastal villages of Italy and France—places where streets wind between buildings without a single traffic light in sight. These settlements, Parolek observed, share one essential quality: they were conceived long before the automobile arrived. “They were designed around accommodating people,” he explains. Yet most people only experience such spaces as tourists. Why, he wondered, couldn’t they actually live there?
The answer reveals a historical bargain cities made decades ago. Urban planners reshaped entire metropolises to serve cars rather than humans. Streets widened into rivers of asphalt. Neighbourhoods sprawled outward, isolating families in quiet cul-de-sacs. Air thickened with pollution. Social connection withered. Loneliness spread like an epidemic. For a long time, this seemed the inevitable cost of modern life.
But something is shifting. Research now demonstrates what many have long suspected: walkable cities produce happier residents. People feel less isolated. Their health improves. Life satisfaction climbs. Around the world, cities are experimenting with these principles—Copenhagen’s Nordhavn district, Barcelona’s superblocks, the emerging 15-minute city movement. For visitors, Culdesac offers a tangible glimpse of what urban life might become when communities prioritise people over pavement.
Building the Impossible in the Desert
What makes Culdesac truly audacious is its location. Tempe sits within greater Phoenix, a sprawling metropolitan region built entirely around the assumption that everyone owns a car. Public transport barely exists. The very idea of thriving without a vehicle seems fantastical here. When the first residents moved in during 2023, sceptics openly doubted whether a car-free neighbourhood could possibly survive in such a car-dependent landscape.
The architects recognised this challenge and reframed the question. Rather than simply removing cars, they designed what Parolek calls a “car-free, but mobility-rich” community. The 17-acre neighbourhood contains everything daily life requires: restaurants, shops, a Korean convenience store, medical offices, a dog park, a swimming pool, a gymnasium, and shared workspace. Most necessities sit within a short walk. For journeys beyond the neighbourhood, a light rail station opens directly onto the plaza, whisking residents to downtown Phoenix or the airport in minutes. Waymo self-driving robotaxis handle longer trips. E-bikes from Archer’s Bikes offer local exploration. For occasional car needs, residents access shared electric vehicles at five dollars per hour.
Sheryl Murdock chose Culdesac precisely because of these mobility options. While completing her postdoctoral research in ocean sustainability at Arizona State University, she wanted to reduce her carbon footprint. The light rail carries her to campus in ten minutes. Supermarkets lie similarly close. She cycles around Tempe, which holds the status of Gold-Level Bicycle Friendly Community. When she ventures further, the shared car system provides access without ownership. “Being in Culdesac has taught me that I much prefer the concept of the 15-minute city,” she reflects. “I don’t want to have to get in my car to do everything.”
The Mathematics of Cleaner Air
The environmental mathematics are compelling. According to the United Nations, switching from private vehicles to public transport, bicycles, and walking can reduce an individual’s carbon emissions by 2.2 to 3.6 tonnes annually. Once Culdesac reaches full capacity—roughly 760 units housing 1,000 residents—the neighbourhood will prevent approximately 3,000 tonnes of greenhouse gases from entering the atmosphere every year. That’s equivalent to the annual emissions from hundreds of conventional cars, simply erased from existence through thoughtful urban design.
Cooling a Burning City
Phoenix last year endured 143 consecutive days at or above 38 degrees Celsius. The city has become synonymous with extreme heat. Culdesac’s designers borrowed strategies from places that have managed intense sun for centuries: the whitewashed villages of Greece, the sun-baked towns of Italy, the colonial architecture of Mexico.
Every building in Culdesac wears white walls and roofs, reflecting sunlight far more effectively than the sandy-coloured homes typical throughout Phoenix. Buildings cluster tightly together—something made possible because no space needs allocation for roads or car parks. This close proximity means structures constantly shade one another. The narrow pedestrian pathways, called “paseos” in Spanish, function as architectural channels, funnelling desert breezes through the neighbourhood. Every apartment includes windows on opposite sides, enabling cross-ventilation and natural cooling.
The result astonished researchers from Harvard University who measured ground surface temperatures in 2023. Within Culdesac, pavement remained 17 to 22 degrees Celsius cooler than the surrounding streets. This microclimate—created through absence of asphalt, strategic shade, careful airflow, and desert-adapted landscaping—transforms the immediate environment.
A Neighbourhood That Breathes
Remove the cars, and something unexpected happens: community flourishes. Twenty-one small businesses now operate within Culdesac’s boundaries, ranging from a James Beard-nominated Mexican restaurant to ceramics studios, a bicycle shop, and a sustainable clothing boutique. Zoning rules permit residents to operate enterprises from their apartments, creating opportunity for entrepreneurs. On market days, live musicians play whilst visitors browse handmade pottery and sample blue corn croissants from local bakeries.
These weren’t accidents. They were consequences of design. “Once you pull the cars out,” Parolek observes, “there’s so much more opportunity to make a vibrant, thriving community.”
Without vehicles flowing through streets, neighbours encounter each other constantly. They pause to chat. They recognise faces. They form bonds. Culdesac residents note that despite being technically an apartment complex, the neighbourhood feels more like a village. The community attracts people already committed to sustainability and social engagement—individuals who naturally gravitate toward shared values. “It’s like finding your people,” Murdock says, describing how residents bond over their commitment to a different way of living.
A Model Spreading Outward
Culdesac’s success has shifted conversations about what American development could become. Erin Boyd, the company’s government relations director, emphasises the significance: “Culdesac Tempe has shown that people do want to live car-free in the US, even in a metro area like Phoenix that’s often seen as the poster child for car dependency. This success has shifted the conversation around what’s possible in American development.”
The company is planning expansions elsewhere across the country. Municipal governments, transit authorities, and developers have begun requesting consultations, eager to understand how Culdesac achieved what seemed impossible.
A Glimpse of Tomorrow
For visitors walking through Culdesac’s paseos, cycling past whitewashed walls, or sitting in the central plaza with a drink in hand, the neighbourhood offers something precious: proof that another way of building cities is possible. Time-honoured architectural principles—narrow streets, close quarters, human-scaled spaces—combined with modern mobility solutions and genuine community commitment, can create places where people thrive.
In the heart of Phoenix, where the sun beats down relentlessly and sprawl stretches endlessly, Culdesac whispers a quiet question to America: what if we chose differently?
