Rancho del Diablo Eichlers

Rancho del Diablo Eichler Community 

Nestled at the eastern edge of Concord, Rancho del Diablo is one of the city’s three historic Eichler tracts (the others are Rancho de los Santos and Parkwood Estates). Built in the early 1960s (c.1963–64), Rancho del Diablo comprises roughly 50 Eichler homes eichlerhomesforsale.com. These mid-century modern residences were primarily designed by architects Claude Oakland and Jones & Emmons eichlerhomesforsale.com. Together they showcase Joseph Eichler’s vision of indoor-outdoor living. Today Rancho del Diablo is known as Concord’s “crown jewel” of Eichler living eichlerhomesforsale.comen.wikipedia.org. It offers larger-than-average lots (many around 0.15–0.20 acres – e.g. one 1963 example sits on 7,280 sq ftredfin.com), peaceful streets and panoramic views of Mt. Diablo. Conveniently, the neighborhood has easy access to Concord’s BART station and major highways redfin.comgoforthrealestate.com.

• Concord Eichler tracts: Concord contains about 175 Eichler homes across three neighborhoods en.wikipedia.orgeichlerhomesforsale.com. Rancho del Diablo’s ~50 homes were built 1963–64, making it a showcase of Eichler’s California Modern style eichlerhomesforsale.comen.wikipedia.org. It sits on gently rolling terrain under the Diablo foothills, with some homes enjoying sweeping views of Mount Diablo.
  
  

• Architects & models: The tract’s original builders offered three floorplan models. Two of them feature central atriums and distinctive pitched (sloped) roofs, while the third model has a flat roof usmodernist.orgusmodernist.org. (In fact, USModernist archives note: “three styles in the development with two atrium styles with pitched roofs… [and] flat roof” for one model usmodernist.orgusmodernist.org.) This mix of rooflines is unusual for Eichler tracts. For comparison, nearby Parkwood Estates (just a half-mile away) offered more dramatic A-frame and peaked models usmodernist.orgeichlerhomesforsale.com.

Architecture & Design

Rancho del Diablo homes epitomize Eichler’s modernist design. They feature post-and-beam construction with soaring (often tongue-and-groove) wood-paneled ceilings and expansive floor-to-ceiling glass walls that blur the line between indoors and out en.wikipedia.orgeichlerhomesforsale.com. Each house centers on an open-air atrium entrance, bringing light deep into the floorplan. Signature elements include sliding glass doors throughout, Philippine mahogany wall paneling, and concrete slab floors with embedded radiant heating en.wikipedia.orgeichlerhomesforsale.com. In short, Rancho del Diablo Eichlers have all the hallmark mid-century features – clean lines, open layouts, clerestory windows, and a strong indoor-outdoor flow en.wikipedia.orgeichlerhomesforsale.com.

• Atrium & glass: Every home has a glass-lined atrium entry or courtyard. This creates a private outdoor room that can be viewed from multiple rooms en.wikipedia.org. (Later Eichler plans introduced these distinctive atriums as an “open-air, enclosed foyer” to blend interior and exterior en.wikipedia.org.)

• Open plan: Interior walls are minimized in favor of large, airy living spaces. Exposed wood beams and white-painted brick or plank walls give a minimalist, clean look. Many owners have preserved or restored original touches like mahogany cabinetry, built-in bookcases, and parquet or cork floors.

• Radiant heat: Original Eichler radiators are typically hot-water radiant coils in the slab, supplying even, silent heat en.wikipedia.org. (Central HVAC was not original to Eichlers but many homeowners have retrofitted mini-splits or added forced-air AC.)

• Lot layout: Lots in Rancho del Diablo tend to be generous (often 7–9K sq ft)redfin.com, with rear yards shaded by mature trees. Streets like Wilson Lane and Sacramento Street wind quietly through the tract, contributing to a peaceful suburban vibe.

Community Vibe & Lifestyle

Rancho del Diablo has a friendly, family-oriented atmosphere. In the 1960s Concord was a blue-collar, family-centric city, and that community spirit persists eichlernetwork.com. Eichler Network described Rancho del Diablo as a “family-friendly, generally working-class town” community of Eichlers eichlernetwork.com. Neighbors here tend to know each other well: casual gatherings and annual block parties are common. In recent years a wave of design-minded buyers has moved in, so the neighborhood is becoming an enclave of mid-century enthusiasts eichlernetwork.com. Many new homeowners are professionals in their 30s–40s who bought sight-unseen precisely for the Eichler character eichlernetwork.com, eichlernetwork.com.

Because Concord Eichler homes have been more affordable than in Silicon Valley or Walnut Creek, they have largely avoided the “teardown” boom. As one local observer put it, Rancho del Diablo Eichlers are “the cheapest Eichlers you can buy” in the Bay Area eichlernetwork.com. Lower land values historically attracted buyers who wanted to preserve rather than replace these homes. The upshot is that the neighborhood’s original Eichlers are mostly intact, with many owners lovingly maintaining the mid-century style eichlernetwork.com, eichlernetwork.com. These homes rarely trade at the sky-high prices of Silicon Valley Eichlers, so design-forward buyers see Rancho del Diablo as a mid-century gem with great value eichlernetwork.com.

Nearby Eichler Tracts

For context, Rancho del Diablo is flanked by two other Concord Eichler neighborhoods. Rancho de los Santos (immediately to the west, around West and Salem Streets) is much smaller – often nicknamed “Rancho del Diablo #2” – with roughly a dozen homes built by Oakland (with architect Kinji Imada) in the mid-1960s. Its designs closely mirror Rancho del Diablo’s style. Parkwood Estates (east of RDD, between Gainsborough and Merridan Drives) is larger (about 70 homes) and was developed by Claude Oakland in 1964 usmodernist.org. Parkwood is notable for its underground utilities – there are no overhead power lines – which keeps the skylines clean eichlerhomesforsale.com. Parkwood’s models include steep A-frames and peaked atrium plans (more dramatic rooflines than RDD). By comparison, Rancho del Diablo’s flatter pitch makes for a subtler profile. In both neighborhoods you’ll find the same Eichler hallmarks: radiant floors, post-and-beam planes, and glass walls en.wikipedia.orgeichlerhomesforsale.com.

Renovations & Buyer Considerations

While Rancho del Diablo Eichlers are charming, buyers should be aware of special maintenance and renovation issues. Many original features (like skylights, tar roofs, and radiant coils) can show their age. For example, the in-floor radiant system – plumbing embedded in the concrete slab – can eventually leak or corrode atriare.com. It’s wise to have a professional inspect the boiler and radiant loops. Roof condition is another concern: pitched-roof Eichlers in RDD may have built-up or tile roofing that can wear out, while flat-roof models can be prone to leakage if not well-maintained. (One recently restored RDD home, for instance, included a brand-new roof with a 15-year warranty as part of its renovation theresaleerealtor.com.) Buyers should also check for any rot or termite damage in the exposed wood beams and decks atriare.com.

Importantly, renovations in Eichler homes demand sensitivity. These iconic designs rely on cohesion of materials and light. Heavy-handed remodels (especially in atriums or removing walls) can undo the very appeal of the home. The best modernizations respect the original Eichler ethos – for example, restoring mahogany woodwork rather than replacing it, or updating kitchens with built-in cabinetry that complements the style. (Notably, owners who have sold Rancho del Diablo Eichlers report that today’s buyers want to preserve the Eichler look eichlernetwork.com.)

Watch-outs for buyers: Confirm the roof type (pitched vs. flat) and inspect it thoroughly. Check the radiant heat system’s age and look for any past slab repairs. Evaluate whether any previous owners enclosed atriums or subdivided spaces – such changes should be undone carefully if possible. Also consider that Eichler walls are often non-load-bearing, but load-bearing beams are critical – have them checked. In short, be prepared for maintenance on original features, and budget for smart updates (new HVAC, insulation, windows) that improve comfort without erasing character.
