These Brothers Aren’t Just Building Cabins—They’re Building on Family Tradition

The rugged, sun-drenched landscapes of southern Arizona’s "sky islands" offer a stark contrast to the sprawling urban centers of Phoenix and Tucson. In these high-altitude ecological refuges, where the desert floor meets forested mountain peaks, the Steen family has spent over four decades redefining the concept of home. For brothers Benito, Kalin, and Arjuna Steen, the red earth and golden straw of the San Rafael Valley were not just the backdrop of their childhood—they were the very ingredients of their shelter. Today, as master carpenters and proponents of sustainable architecture, Benito and Arjuna are not only maintaining the structures their parents built but are also expanding a multigenerational legacy of natural building that challenges modern industrial construction norms.

The story begins in the 1980s when Bill and Athena Steen, artists and visionaries of the burgeoning natural building movement, purchased a 40-acre swath of high-desert land near the Mexican border. At the time, the couple was driven by a desire to live simply and sustainably, far from the conveniences and constraints of the grid. They turned to straw bale construction, a method that involves stacking bales of straw as structural or insulating units and coating them with thick layers of earthen plaster or lime. While the technique had roots in the late 19th-century Nebraska plains, the Steens became pioneers in adapting it for the arid Southwest, blending it with traditional adobe and clay finishes to create homes that were both thermally efficient and aesthetically profound.

Growing up on this remote homestead was an immersive apprenticeship in the laws of nature and the mechanics of craft. For the Steen brothers, the distinction between work and play was often blurred. While other children were playing with plastic blocks, Benito and Arjuna were literally shaping the walls of their bedrooms. They learned to identify the right consistency of clay, the structural integrity of a well-tied bale, and the patience required for the slow curing of earthen floors. The property served as a living laboratory for the Canelo Project, the family’s non-profit organization dedicated to "connecting people, culture, and nature" through the exploration of sustainable living and building.

Benito Steen admits that as a young child, he didn’t always see the "paradise" in the hard labor of the homestead. The remote location meant that every repair, every expansion, and every daily chore required physical effort and family cooperation. However, by the age of eight, the tactile satisfaction of the workshop began to take hold. He recalls the ethereal quality of the morning light filtering through clouds of sawdust and the visceral connection of harvesting raw materials directly from the land. This wasn’t just construction; it was a form of stewardship. The family would venture out in an old truck to gather downed logs from the surrounding national forests or haul buckets of clay from nearby deposits, ensuring that every element of their home had a story and a source.

This intimate relationship with materials is what Benito identifies as the "soul-level" of building. In an era where most construction materials are anonymous, mass-produced products shipped from across the globe, the Steen approach is radically localized. When you mill your own planks and shape your own bricks, Benito argues, you develop an intuitive understanding of the building’s life cycle. This philosophy has guided his evolution into a master carpenter. His work today is a sophisticated marriage of rugged natural building and fine woodworking, characterized by clean lines, organic textures, and a deep respect for the inherent properties of wood and earth.

The technical advantages of the Steens’ methods are backed by significant environmental data. Straw bale walls can provide an insulation value of R-30 to R-35, nearly double that of standard stud-frame construction. In the extreme temperature swings of the Arizona high desert, this thermal mass keeps interiors cool during the blistering summer days and retains heat during the freezing winter nights. Furthermore, by using agricultural waste (straw) and local soil, the carbon footprint of these buildings is a fraction of that of concrete or steel structures. This relevance has only grown in the 21st century as the global construction industry seeks ways to mitigate its massive carbon emissions.

Despite his deep roots, Benito Steen initially resisted a career in the family business, perhaps a natural rebellion against the heavy lifting of his youth. Yet, the pull of the craft proved irresistible. He eventually found himself drawn back to the Canelo Project, helping lead workshops that teach students from around the world how to work with lime, clay, and straw. These workshops serve a dual purpose: they preserve ancient building techniques that are at risk of being forgotten and empower individuals to take agency over their own living environments. Benito notes that many people come to the workshops intimidated by the idea of building, only to find a profound sense of peace and capability once they get their hands in the mud.

Transitioning from the family homestead to professional contracting presented new challenges, particularly logistical ones. Benito and Arjuna often take on projects in the most inaccessible corners of the Arizona hills—places where "off-grid" isn’t just a lifestyle choice, but a geographical reality. These sites are frequently characterized by narrow, winding dirt tracks, steep inclines, and unpredictable weather. To manage these builds, the brothers require equipment that matches their philosophy of efficiency and durability.

Lately, the 2026 Nissan Frontier has become an essential tool in their arsenal. In the world of remote construction, a truck isn’t just a vehicle; it’s a mobile workshop and a lifeline. The Frontier’s 7,150-pound towing capacity allows the Steens to haul heavy loads of specialized lumber, clay, and equipment into terrain that would stymie larger, more cumbersome vehicles. "I hate driving big trucks around," Benito says, "but having a small, compact truck that also has a big towing capacity—that’s been huge." The ability to navigate tight mountain switchbacks while carrying the weight of a build is crucial for their specific niche of "out there" construction. It allows them to maintain their commitment to building in remote, natural settings without the logistical nightmares usually associated with such locations.

The continuity of the Steen legacy is perhaps most evident in the way the family lives today. Both Benito and Arjuna have chosen to remain on the 40-acre homestead, raising their own children in the same environment that shaped them. The compound has evolved into a cluster of handcrafted dwellings, each reflecting the unique style and growth of the family members. This multi-generational living arrangement provides a support system that is increasingly rare in modern society. Benito describes the experience as "a big hug," noting the joy of seeing his son play alongside Arjuna’s son in the same hills they once roamed.

For the Steens, the act of building is inseparable from the act of parenting. By involving the next generation in the maintenance and creation of their homes, they are passing down more than just technical skills; they are instilling a value system based on self-reliance, environmental responsibility, and the importance of family bonds. The "legacy" mentioned in the title isn’t just a collection of buildings—it’s a way of being in the world.

As the world grapples with a housing crisis and the escalating effects of climate change, the work of Benito and Arjuna Steen offers a compelling alternative. Their projects serve as a reminder that the most sophisticated solutions are often found in the simplest materials. By combining the wisdom of the past with the tools of the present—whether it’s a centuries-old plastering technique or a high-performance 2026 Nissan Frontier—the Steen brothers are carving out a sustainable future in the rugged heart of Arizona. Their lives stand as a testament to the idea that when you build a home with your own hands, you aren’t just creating shelter; you are crafting a foundation for a life well-lived, rooted in the earth and bound by the strength of family.
