The Construction of Twenty Mile House

The Construction of Twenty Mile House was Bernadette Fox’s answer to a practical shortage of money and a restless need to make something new: a house whose materials would come from within twenty miles, yet whose finished rooms would feel light, warm, and carefully composed. The project turned local limits into a design principle, drawing its structure and surfaces from nearby supply, salvage, and labor. Its construction also made visible a particular form of architectural authorship: Fox’s command of materials and permits, and her ability to build with David Walker even without conventional plans.

Origins and the Twenty-Mile Principle

Bernadette Fox and Elgin Branch moved into the Beeber Bifocal House in 1991. Fox was already restless for another project, but the factory home had absorbed most of their resources. Judy Toll found her a scrubby plot on Mulholland in Hollywood, near Runyon Canyon, with a flat building pad and a view of the city. A neighboring parcel was also for sale, but Fox and Branch could not afford to buy both. The chosen site therefore offered a place to build, but not the expanded property Toll had suggested.

Fox made the material constraint explicit: the house would use materials sourced within a twenty-mile radius. Proximity meant more than buying an item nearby; steel imported from China would not qualify simply because a Home Depot stocked it a mile away. The rule directed attention toward the origins of building materials and made sourcing part of the architectural work. David Walker agreed to take on the challenge. Paul Jellinek later emphasized the partnership’s importance: Walker could work without plans, an unusual capacity that matched Fox’s way of moving from an idea toward a buildable house.

Building Through Local Supply and Salvage

After receiving a permit for a three-bedroom, four-thousand-square-foot glass-and-steel box, with a detached garage and guesthouse, Fox began construction. The specifications on paper gave the project a conventional outline; the supply chain on the ground was more improvised. A cement factory in Gardena supplied sand, which Fox mixed on-site. A recycling yard in Glendale contacted her when steel beams arrived. Materials from a dump were acceptable even when the materials themselves had originated outside the radius, and a house being demolished down the street supplied useful contents through its dumpster.

Tree trimmers provided wood that Fox intended to use for cabinets, flooring, and furniture. Salvage here was not limited to conspicuous scraps or decorative reuse: material from different sources was assigned work throughout the house. The distinction between a discarded object and a building resource depended, in part, on what it could become. That practical way of seeing things gave the twenty-mile rule its force. It shaped procurement, construction, and the eventual character of the rooms rather than remaining a slogan detached from the process.

The building was also made through direct exchanges with workers. Ellie Saito recalled arriving in Los Angeles on her way to Palm Springs to meet prefab developers and stopping by the site. Fox, in overalls and a tool belt, was laughing and speaking broken Spanish with workers; Saito joined in by rolling up her Issey Miyake and helping dig a trench. The episode records construction as shared physical work, not simply a design handed off from an office. Walker described Fox explaining what she wanted when a welding job arose, with the welder then providing an answer. Her focus remained on getting the house built, even in interactions where a subcontractor might show her disrespect.

The House and Its Recognition

In 1992, when green architecture was being discussed but before LEED, the Green Building Council, or Dwell, Paul Jellinek brought a group connected to the MacArthur Foundation to see the house. They may have expected an inelegant structure made from license plates and tires; instead, they entered a sparkling glass box with clean lines. There was no drywall or paint. Concrete formed the floors, wood covered the walls and ceiling, and the counters were exposed aggregate flecked with broken glass that supplied translucent color. Despite the warmth of those materials, the interior felt lighter than the exterior.

That contrast matters to the project’s achievement. The nearby and salvaged materials did not make the finished house read as a pile of leftovers. Their textures and colors belonged to a coherent design, and the lightness of the interior complicated any assumption that resource-conscious building had to look makeshift. The visitors responded by laughing at the beauty of the place. On the day of the visit, Fox was building the garage, pouring concrete into forms and making tilt-up walls. The MacArthur visitors took off their jackets, rolled up their sleeves, and helped with the work. Their participation turned the visit into a brief extension of the construction itself.

Completion and Consequences

The recognition that followed the visit enabled Fox to let go of Twenty Mile House and put it on the market. Toll recalled that Fox wanted to list it and find another property without a shared driveway. The adjoining land had since become the setting for Nigel Mills-Murray’s White Castle, a fourteen-thousand-square-foot Tudor-style mansion faced in white marble. At first, the two building crews were cordial: Fox borrowed an electrician from the neighboring project, and she persuaded an inspector not to revoke its grading permit. The contrast between the mansion’s scale and material and Fox’s locally sourced house framed two very different approaches to building side by side, though their early dealings were cooperative.

Twenty Mile House therefore marked both an achievement and a transition. Its locally sourced materials made the twenty-mile limit concrete, while its glass, wood, concrete, and aggregate gave the constraint an unexpectedly composed form. The project also demonstrated the practical intelligence behind Fox’s work: she found a builder comfortable without plans, obtained a permit, organized an improvised network of nearby materials, and kept construction moving on-site. Recognition made it possible for her to sell the house and seek another place to build, so the project’s success was not an ending so much as a release from the house it had brought into being.
