In California, in 1915, Bertram Goodhue re-interpreted masterful Spanish Baroque and Spanish Colonial architecture complete with the latter's traditional Churrigueresque detailing into what became known as the Spanish Colonial Revival Style of architecture. This was for the significant commission of the El Prado Quadrangle's layout and buildings at the major 1915 Panama-California Exposition, located in San Diego's Balboa Park. He was the lead architect, taking over from Irving Gill, with Carleton Winslow Sr. and Lloyd Wright assisting. The Panama-California Exposition's style was seen by many and widely published, becoming extremely influential in California and the Southern and Southwestern United States. It led to California's assimilation of Spanish Colonial Revival Style architecture as its dominant historical regional style, which continues to this day. The singular style for the rebuilding of Santa Barbara after its 1925 destruction by a major earthquake was drawn from the local Mission Revival and Goodhue's Panama-California Exposition Spanish Colonial Revival style trends. Examples of influential private Californian commissions, both extant registered landmarks now, are his 1906 J. Waldron Gillespie Estate El Fureidis and 1915 Dater - Wright Ludington Estate Dias Felices — Val Verde in Montecito. Goodhue and Gillespie had done a six-month research and acquisitions tour together through Egypt, Persia, and the Arabian Peninsula before collaborating on the classic Persian gardens layout and Roman and Spanish Colonial Revival residence at El Fureidis. Goodhue's Spanish Colonial Revival style work went on to dominate the Hawaiian architecture of public buildings and estate residences during the 1920s building boom in the Territory of Hawaii.
