20 North Roxbury Drive in Beverly Hills is a 1920s Spanish Colonial Revival that has been the backdrop for a string of high‑profile owners. The 8,434‑square‑foot house, designed in 1927 by Ralph C. Flewelling—who also designed the city’s City Hall—was briefly owned by Madonna before being purchased by actress‑turned‑renovator Diane Keaton in 2007 for $8.1 million. Keaton, who died this month at 79, turned the property into a showcase of her design sensibilities, working with longtime collaborator Stephen Shadley to restore its original character while infusing it with contemporary flair.
Keaton’s renovations emphasized the home’s Spanish Revival roots: soaring beamed ceilings, archways, terracotta tile, and carved wooden details were preserved, yet she reimagined spaces to suit modern living. The grand foyer was converted into a library with a seating area, a nod to her love of books. The kitchen was transformed into a vaulted, beam‑lined room anchored by a fireplace and an oversized farmhouse table, blending Spanish hacienda vibes with rustic farmhouse elements. She added dual bathrooms to the primary suite and installed a dramatic cactus‑lined front yard that defied Beverly Hills zoning norms, replacing the required hedge with a bold, desert‑inspired landscape.
After Keaton’s tenure, Ryan Murphy acquired the house in 2010 for $10 million, having originally listed it for $12.99 million in 2009. Murphy later sold it in 2015 to Cailin and Seth Wunder for $16.25 million. The Wunders, a private‑equity executive and an artist, embraced the property’s expressive layers, maintaining Keaton’s design work while adding their own curated touches. They highlighted the home’s central open‑air courtyard—an architectural signature of Flewelling—as the emotional heart of the estate.
The listing now prices the home at $25 million, positioning it as a “legacy property” where Hollywood glamour meets modern luxury. The estate boasts five fireplaces, a gym, a wine cellar, a guest house, a pool, and a sports court, all set amid lush landscaping. The primary suite features an ensuite bathroom, while secondary bedrooms and a den provide ample space for guests and family. The property’s history of celebrity ownership, combined with Keaton’s meticulous restoration, gives it a unique appeal that goes beyond its architectural pedigree.
Keaton’s influence is evident throughout: the library’s intimate atmosphere, the vaulted kitchen’s dramatic ceilings, the cactus front yard’s bold statement, and the overall blend of Spanish Revival charm with contemporary design. Her work on the house is described by real‑estate agents as “one of the most prolific architectural and design minds” in the community, with only a handful of peers matching her aesthetic.
Cailin Wunder, who has long admired the property, recalled first seeing it in Architectural Digest’s 2008 issue and feeling an instant connection. She described the home as a place where art, history, and craftsmanship converge, a sentiment echoed by the listing’s emphasis on the house’s authentic character.
The Wunders are now ready to move on, with Cailin citing a “three‑ or four‑year itch” that drives her creative eye toward new projects. The listing highlights the home’s legacy status and its potential for future owners to experience a blend of classic Spanish Colonial Revival architecture and Keaton’s distinctive design legacy.
