San Ramon's Casa Mañana: 1965–1969 homes & subdivision history

Welcome to Casa Mañana

Between 1965 and 1969, McGah-Bailey brought their vision of the future to San Ramon in the form of Casa Mañana—“House of Tomorrow.” But timing is everything, and their futuristic homes had a slow takeoff.

The subdivision debuted with three model homes priced between $23,500 and $26,500—on the high side for the area. One standout featured the Island Kitchen, a forward-thinking layout with a seating bar that felt more 1975 than 1965. But across the street, H.C. Elliott’s Crestview homes offered similar space for less. The comparison wasn’t flattering, and buyers noticed.

A course correction

By mid-1966, McGah-Bailey hit refresh. Out went one of the pricier models, and in came four smaller, more affordable homes—complete with front lawns, fencing, and insulation. The new starting price? Just $19,950. No need to haggle for extras—everything but the furniture was included.

The rebranded message was clear: These are homes for today. Even carpeting, once an upgrade, became standard fare by 1967. “All you do is move in,” promised the ads.

A full house of models

Between 1965 and 1967, Casa Mañana expanded to include nine model homes. The complex, located at Davona Drive and Duke Drive, showcased the range—from cozy 1,125 sq. ft. cottages to sprawling 2,190 sq. ft. ranchers with optional fifth bedrooms.

By 1968, the lineup had slimmed to just four plans, and by 1969, the neighborhood was built out and fully sold. Though McGah-Bailey never returned to build again in San Ramon, their one and only contribution left a curious and charming footprint in the city’s suburban story.

A final glance at the “homes of tomorrow”

Today, Casa Mañana may no longer be the new kid on the block, but its homes still whisper of mid-century optimism. Tucked into San Ramon’s quiet streets, these ranchers carry their original character with surprising grace—breezy floor plans, wide lots, and yes, the occasional surviving island kitchen.

While other subdivisions grew with flashier designs or larger footprints, Casa Mañana has remained charmingly understated. These were homes designed not just to impress, but to live in—carpeted, fenced, and lawned from day one. In a time when “extras” often came extra, McGah-Bailey gave buyers a turnkey slice of the good life.

For those who appreciate a bit of real estate time travel, Casa Mañana offers a glimpse into a builder’s one-shot dream: practical, hopeful, and a little bit ahead of its time.

Welcome to San Ramon Country Club Park In the early 1960s, Country Club Park wasn’t just a place to live—it was a way of life.

Walnut Grove Series: 1966–1968 homes in Pleasanton Valley

Welcome to the Walnut Grove series homes at Pleasanton Valley When Morrison Homes broke ground on its second phase in Pleasanton Valley — the Walnut Grove Series — it did so with a nod to the land’s past. Built between 1966 and 1968, the homes were sited on generous lots — many measuring over 11,000 square feet — and often came with a quiet legacy: up to six mature walnut trees left from the original orchard. These weren’t just new homes; they were new roots planted in old soil. A view from Hopyard Road in 1968 shows the Pleasanton Valley model home complex—fresh sidewalks, young trees, and homes awaiting families. The photo hints at Pleasanton’s rural feel before suburban expansion. Pleasanton in the mid-to-late 1960s was undergoing a slow but steady transformation. While nearby Dublin was developing its first shopping centers and San Ramon remained mostly pasture, Pleasanton was emerging as a town with modern schools, growing families, and a suburban identity still grounded in r...

Pleasanton Valley history: Pleasanton's 1964–1979 neighborhood development

From 1964 to 1979, Pleasanton Valley quietly transformed Pleasanton from a rural crossroads into a thriving hometown. Developed by Morrison Homes on the former Orloff Ranch, this neighborhood became one of the city’s largest and most defining suburban expansions—home to over 1,470 families. For 15 straight years, Pleasanton families had something new to look forward to: a fresh model home to tour, a new floor plan to dream about, and another reason to fall in love with this growing community. Map of the Pleasanton Valley neighborhood in Pleasanton, California. A neighborhood of birds, trees—and families Locals often called it “Birdland” or “The Woods,” thanks to the whimsical street names inspired by birds and trees. But the names weren’t what made Pleasanton Valley special. It was the families. Generations of kids rode bikes past new construction, splashed through sprinklers in front yards, and chased each other through parks and cul-de-sacs. Nearly everyone in Pleasanton at the t...
