Ray Kappe did more than just help define the architectural ethos of Los Angeles in the 1950s, ’60s, and beyond. The late architect and educator co-founded the highly regarded Southern California Institute of Architecture (SCI-ARC), now located in downtown LA’s Arts District. Given his undisputed standing as a leading architectural innovator, the houses he designed are a coveted and exclusive event whenever one comes up for sale.
A contemporary mansion in the Santa Monica Valley, available new for $10 million, Cappy designed in 2012, seven years before he turned 92. The design emphasizes SoCal’s indoor-outdoor living, and the structure has achieved LED Gold certification, one of the highest environmental sustainability ratings. F. Ron Smith and David Berg of Smith & Berg Property Group repped the listing with John Skinner at Compass.

A massive two-sided steel fireplace separates the living and dining rooms.

The property offers open views that sweep over the mountains to the Pacific Ocean from its airy interior and numerous outdoor spaces. For example, the primary suite offers a private deck perfect for posting while watching the sun set over the water, or you can take in the ocean view from the sleek shower in the bathroom.
A pool and infinity-edge spa are complemented by both covered and uncovered patios for lounging, while additional al fresco space can be found on the roof deck, where there’s a fire pit you can huddle around while enjoying the cool sea breeze.
The open floor plan includes a double-height foyer with a floating staircase and a boundless Corten steel fireplace with a marble hearth that stands between the living and dining rooms. The Arkenia chef’s kitchen is outfitted with Wolf and Mile appliances, a textured alligator Kaiser Stone backsplash, and a minimalist butler’s pantry.

The roof deck offers a fire pit where you can cozy up on cold winter evenings.

In addition to the primary suite, three guest and family bedrooms each—one of which is located on the main floor. It also has a private terrace, while a breezy home office, a cozy media room, and a two-car garage complete the home.
Cappe has designed more than 100 homes, and several have recently popped up for sale. In early 2024, one of his last commissions hit the market for $16 million. Several months later, a pair of midcentury condos in the Hollywood Hills hit the market for a combined $1.9 million. And earlier this year, a 1980s glass, concrete and steel home in Santa Monica’s rustic valley sold for about $3.65 million.
