This distinguished mid-century modern architectural masterpiece was designed by Valentine J. Powelson, AIA, in 1960, the same year he created Rancho Mirage’s celebrated Maranz House, which was immortalized on the cover of Palm Springs Weekend magazine. Even if its name escapes you, the silhouette of its legendary “butterfly roofline” is unmistakable. Similarly, the residence located at 2427 Solar Drive in Nichols Canyon, just above the hiking trails of Runyon, has been christened “The Sunbow House,” and is instantly defined by its dramatic “folding plate roof.” An architectural jewel of its time, the home still stands as an absolute icon of the mid-century era.


Valentine J. Powelson, nicknamed Val by friends and colleagues, was a Los Angeles native and brought an engineer’s precision and a designer’s imagination to the Southern California modernist landscape. Educated in structural engineering at UCLA, he began his career in the mid-1950s as a licensed contractor and designer, collaborating with notable figures such as architect Jon Jerde. Though he formally became a licensed architect in 1986, Powelson’s architectural voice was already well established, with an oeuvre that continues to resonate in Los Angeles and Palm Springs today.

In his early years, Powelson focused primarily on residential commissions, creating daring hillside homes in the Hollywood Hills celebrated for their dramatic folding-plate rooflines and seamless integration of nature into structure. His work in Palm Springs and Rancho Mirage cemented his place within the Palm Springs School of Architecture, particularly through his innovative use of hyperbolic paraboloid forms, sometimes referred to a “folding plate” or “butterfly” rooflines. Among his most recognized projects are the Gummo Marx Residence (1957), the Da Vaal Estates cooperative residences (1960), the Maranz Residence (1960), and the Morris-Weisbard Residence (1961)—all listed on the Register of Historic Resources in Rancho Mirage. He also designed the Indian Wells Country Club House (1959), memorably captured in photographs by Julius Shulman.

Powelson’s architectural legacy rests in his bold exploration of geometry and structure, which gave modernism in California an edge both elegant and experimental.
