The G.E. Spencer House arrived in 1952 on a Canon Drive site already rich with architectural history. Designed by the Pasadena firm Smith & Williams, the International style residence occupied land that had been part of the 1911 Cordelia Culbertson estate, a Greene & Greene commission whose accessory garden structures still dotted the property. Rather than clearing the site, the architects chose an unusual path: integrating these earlier elements into a thoroughly modern design. The commission gave Whitney Smith, a Pasadena native who had studied Greene & Greene's work closely and corresponded with Charles S. Greene in the early 1940s, a chance to explore ideas he had developed for Case Study House #12.
The residence responds to its setting through careful siting and the deliberate incorporation of the existing Greene & Greene lath house, which Smith's sketches show him considering as an entrance element. The design follows International style principles with clean lines and an open relationship between interior and exterior spaces. The house demonstrates how mid-century modernism could acknowledge rather than erase earlier architectural layers, creating what the City of Pasadena's Mid-Century Modern Houses Driving Tour describes as "an outstanding response to its setting." The property preserves this rare architectural palimpsest where two distinct California traditions occupy the same ground.
