Twenty Mile House was Bernadette Fox’s experiment in building beautifully with what a place already had—and the house whose destruction became a lasting wound in her life. Set on Mulholland Drive in Los Angeles, it made a rigorous local-materials rule visible in its construction and design. Its demolition erased the building but not its influence: scarce photographs and incomplete plans became the remains of a house remembered both as an architectural achievement and as the center of a personal conflict.

Site and Design

After Bernadette Fox and Elgin Branch moved into the converted Beeber Bifocal factory residence, Fox wanted another project. Real-estate agent Judy Toll found a scrubby parcel on Mulholland near Runyon Canyon, with a flat building pad and a view of the city. The adjacent parcel was also for sale, but Fox and Branch could not afford to buy it. That neighboring property would later become central to the house’s story.

Fox committed to using materials sourced within twenty miles of the site. The restriction was not satisfied by purchasing nearby a product made elsewhere: as Toll explained, the point was not to buy imported steel at a nearby store, but to source the materials locally. The principle made the limitations of a modest budget part of the design method. Paul Jellinek later described Fox’s emerging point of view as one of wasting nothing.

The permitted project was a three-bedroom, roughly 4,000-square-foot glass-and-steel house, with a detached garage and guesthouse. Its construction drew on an improvised network of nearby sources. 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 could be used even if they had originally come from outside the radius, and the dumpster at a nearby demolition site provided another supply. Tree trimmers furnished wood for cabinets, floors, and furniture.

The house was built without the conventional completeness of a set of architectural plans. David Walker could work without them, translating Fox’s ideas into practical solutions on site. When welding was needed, he brought in a worker; Fox explained what she wanted, and the worker supplied an answer. Jellinek emphasized the difficulty of this arrangement for a young woman building on her own, while Walker’s presence gave Fox a collaborator who could help carry the work through. Fox’s attention remained on getting the house built, even when the process involved negotiating with workers who might otherwise have dismissed her.

Construction and Architectural Recognition

The work was active and collaborative rather than remote from the building site. During a visit, architect Ellie Saito found Fox in overalls and a tool belt, laughing and speaking broken Spanish with workers; Saito joined her in digging a trench. The scene matched the house’s practical logic: design, sourcing, negotiation, and physical labor were closely joined.

The finished interior confounded expectations that an experimental, salvaged-materials house would be ugly. Jellinek recalled bringing visitors connected with the MacArthur Foundation, who expected something crude and instead encountered 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 exposed-aggregate counters included broken glass that added translucent color. Though its materials were warm, Jellinek remembered the interior as feeling lighter than the outdoors.

In April 1992, Fox received a call telling her she had been awarded a MacArthur grant. The $500,000 award had never before gone to an architect. Jellinek had recommended her work to a friend affiliated with the foundation, identifying Twenty Mile House as the most exciting thing he saw in architecture. At the time, green architecture was being discussed, but the later institutional prominence of the movement had not yet arrived; the house joined environmental resourcefulness to an arresting visual clarity. When the foundation visitors came to see it, Fox was building the garage and pouring concrete into forms for tilt-up walls. They took off their jackets and helped. The award recognized not only an idea but the ongoing labor of making it real.

Sale and Demolition

The MacArthur recognition enabled Fox to consider letting go of the house and putting it on the market. She wanted a different property without a shared driveway, and Toll began preparing photographs and comparable sales. A buyer approached through a business manager before the house was formally listed. Because Fox still needed portfolio photographs, the sale was to wait until after her return from Europe, allowing the garden time to fill in.

The buyer’s identity was concealed. Toll transferred the title to the business manager, who was purchasing the property for his client, Nigel Mills-Murray, Fox’s neighbor and the owner of the White Castle next door. The arrangement was described as a familiar way for a celebrity to buy property privately. Fox was in Europe when the transfer took place; she did not know that Mills-Murray was the buyer.

Paul Jellinek learned what had happened when he drove to the house with students, intending to show it to them. The gate stood open. Inside the lot, three bulldozers were breaking through the walls and crushing the glass, beams, furniture, lights, windows, and cabinets. Jellinek tried to stop the demolition, then sent his students to form a human chain in front of the machines while he drove to a pay phone and called Fox. He first left an angry message because he thought she had chosen to destroy the house. After learning that she had not known of the sale to Mills-Murray, he called back and told her who the buyer was. There was silence, and Fox hung up.

A building that had taken three years to complete was demolished in a day. Its surviving visual record was meager: Toll’s point-and-shoot photographs and the comically incomplete plans Fox had submitted to the building department. News of the demolition brought grief in architectural circles. Jellinek, while acknowledging how widely Fox was viewed as the victim, later argued that the destruction was her own fault. His judgment sits uneasily beside the account of a sale whose true buyer was hidden from her, leaving responsibility and injury entangled in the house’s afterlife.

The House as a Lasting Wound

For Fox, the loss did not remain a professional disappointment. Looking back on her final year in Los Angeles, she described shame at her behavior in the conflict, anger at Mills-Murray, envy of his continued public success, and self-reproach over how much of her life had become bound to the house. She could dismiss the building outwardly as unimportant, but described that posture as a false front. The house returned instead as a private test of whether she had deserved what happened to it and whether its destruction proved her a failure.

That return was not merely an occasional recollection. Fox described waking at night with her sense of self reassembling around the sequence of her name, the destroyed house, and the conclusion that she deserved it. Other professional honors, including an American Institute of Architects honor, did not cancel the wound; she experienced them as consolation prizes that seemed to confirm the idea that she had failed to overcome the loss. During a later family intervention, Branch used the house to accuse her of remaining trapped in an old grievance, contrasting her continuing distress with the difficulties he faced at Microsoft. The exchange shows how a building’s destruction had become a conflict within the marriage as well as within Fox’s memory.

Afterlife and Rebuilding Proposal

Twenty years after the house’s creation, its continuing significance became the premise of a public design challenge. Green Builders of America and the Turner Foundation invited architects, students, and builders to reenvision the building and use the project to consider what it would mean to build green in the next twenty years. The brief specified a three-bedroom, 4,200-square-foot single-family residence at 6528 Mulholland Drive. Its sole material restriction repeated Fox’s original rule: every material had to come from within twenty miles of the building site. The proposed house therefore differed in specified size from the original permit, while keeping the central constraint intact.

The competition acknowledged the paradox of trying to recover a building that no longer stood and for which few photographs and no complete plans remained. Rather than presenting a definitive restoration, it made reenvisioning the house a way to reopen discussion of its guiding principle. The winner was to be announced at a gala held at the Getty Center grounds and receive $40,000. In that form, Twenty Mile House persisted less as a recoverable object than as a demanding idea: a local materials rule, an architectural work remembered through fragments, and a loss that continued to shape how Fox understood her own creative life.
