Fairorchard Eichlers: Anshen & Allen Mid-Century Design

Inside Sunnyvale's Fairorchard: Anshen & Allen Atrium Homes

By Kevin Limprecht, Founder of the Eichler Vault.

The Fairorchard tract in southwest Sunnyvale represents a critical transitional turning point in Joseph Eichler’s residential program, bridging early mid-1950s closed-front modernism with the fully realized open-air atrium plans that defined the late 1950s. Developed around 1958 across roughly 54 single-story properties along Edmonton Avenue, Edmonton Lane, Edmonton Way, La Salle Drive, Helena Drive, and Wright Avenue, Fairorchard establishes how structural framing, lot orientation, and roofline variation were coordinated to create high-density privacy on former agricultural land.

The primary architectural stewardship of Fairorchard rests with Anshen & Allen, with additional plan refinement from Jones & Emmons. This collaboration introduced four core floor plans ranging from 1,370 to over 1,890 square feet. What distinguishes Fairorchard from earlier Sunnyvale developments like Sunnyvale Manor is its position as one of the earliest sub-developments in the city to incorporate integrated open-air atrium courtyards alongside traditional broad-front L-shaped entry plans. Rather than treating the central outdoor space as an adjunct patio, Anshen & Allen organized the structural post-and-beam grid around this open sky-well, creating a protected perimeter core that distributes light across public living zones and quiet bedroom wings.

The structural organization throughout Fairorchard relies on a strict post-and-beam timber skeleton, utilizing structural Douglas fir post assemblies and long-span glulam or solid timber beams supported by outer concrete block or frame wall panels. The roof forms alternate between low-pitched gables, sweeping flat planes, and broad asymmetrical sheds, which visually break up the horizontal streetscape. In original Anshen & Allen iterations, the street elevation acts as a blank, defensive protective shield, clad in unpainted or dark-stained vertical groove plywood siding. Public life was engineered to orient inward toward the atrium or turn entirely toward the private rear garden behind expansive, non-load-bearing walls of floor-to-ceiling glass.

Inside these structures, the materiality is defined by unpainted mahogany plywood paneling on interior partitions, thin-slab concrete floors housing embedded copper radiant-heating pipes, exposed tongue-and-groove wood ceiling decking, and original slab-door cabinetry. Light transmission is managed by continuous bands of clerestory windows situated directly beneath the exposed beam tails. These high-strip glazing units allow light to track across the ceiling planes throughout the day without violating privacy from neighboring parcels.

Uncovering intact post-and-beam features requires a deep understanding of original floor plans, model variations, and property stewardship. Engage with our private archival network to explore documented histories and collaborate with others committed to modern architectural integrity.

A true "unicorn Eichler" within Fairorchard is defined by an intact original layout that preserves its primary architectural fabric alongside exceptional lot placement. In a tract where many properties have suffered interior sheetrock overlays, removed thin-line radiant slabs, or enclosed atriums, a historically significant home preserves the original Anshen & Allen floor plan with unpainted interior Philippine mahogany paneling, working radiant heating, original sliding glass doors with thin aluminum trim, and an uncompromised atrium core. Crucially, lot orientation determines architectural utility. Properties positioned with a direct south or southwest rear aspect utilize the low winter sun to heat the exposed aggregate interior floors, while deep roof overhangs shield the interior glass walls from high summer thermal gain.

Surviving alterations across Fairorchard reveal varying degrees of preservation stewardship. The most frequent modification involves the enclosure or skylighting of the original central atrium. While skylighting preserves the visual light shaft, enclosing the volume with insulated framing compromises the original ventilation mechanics and the open-air void designed by Anshen & Allen. Similarly, replacing original floor-to-ceiling single-pane glass with heavy vinyl frame assemblies disrupts the visual continuity between interior living rooms and exterior garden spaces. The strongest preserved homes retain their lightweight, minimal-profile glass stops, preserving the direct structural reading from post to glass.

Fairorchard operates as an intentional, planned mid-century micro-environment rather than an isolated strip of houses. The street network incorporates deliberate gentle curves and cul-de-sacs that control vehicular sightlines and reduce pass-through traffic. Positioned directly adjacent to Cupertino Middle School and bounded by primary residential arteries, the neighborhood layout demonstrates Joseph Eichler’s commitment to community-scale site planning.

Documenting the architectural provenance of Fairorchard preserves key details of California’s mid-century modern design history. Within the Eichler Vault and the Eichler Buyers Collective, our focus remains centered on analyzing these structural systems, tracking original model variations, and evaluating surviving architectural fabric. Through detailed field research and shared structural documentation, the Collective functions as a private resource for individuals dedicated to the study, understanding, and ongoing stewardship of historically significant Eichler homes.
