Duc and Elliot's Villa de San Ramon opened in Dublin in April of 1965. Seven models were available in a range of sizes, from 3 to 6 bedrooms. Prices started at $19,900 and ranged to $23,300 for the largest 2-story model.
The following models were available:
- The Casa Bonita, 3 bedrooms, 1258 sq. ft.
- The Californian, 3 bedrooms, 1288 sq. ft.
- The Briarwood, 3 bedrooms, 1440 sq. ft.
- The Casa Serena, 4 bedrooms, 1483 sq. ft.
- The Mount Diablo, 4 bedrooms, 1708 or 1740 sq. ft.
- The Manor House, 5 bedrooms, 1855 sq. ft.
- The Casa Grande, 6 bedrooms, 1855 sq. ft.
The most popular model was the Mount Diablo. The model homes are indicated with an "M" on the map (on Burton Street).
Villa de San Ramon experienced a sales boom in its early phases, but petered out in 1966, culminating in a premature closing in late 1967. Originally intended to build out around 300 homes, Villa de San Ramon built only 187 homes, 156 in the first few phases, and 31 in the final phase. The remaining lots sold to another developer around 1970 (Shamrock Estates).
During the final phase (1966-67), three new models were introduced, two based on earlier models (the Mount Diablo and The Casa Serena) and one entirely new model. In the map, the second-phase lots are enclosed in black lines. Only one home, on the corner of Emerald Avenue and Amador Valley Boulevard, was unique in this phase (perhaps the sales office).
Empty lots in the middle of the subdivision, indicated with a red "X," were built out between 1970 and 1973 by the Shamrock Estates subdivision.
Villa de San Ramon has the distinction of being the only subdivision at this time with a leapfrog pattern of development.
