The Tempo House is a 1959 Ray Kappe residence at 2941 Briar Knoll Drive in the Hollywood Hills, Los Angeles, California 90046, designed for Earl and Betty Clemmons and photographed by Julius Shulman. Built around a round pool beneath an overhead oculus, it is one of the most unusual houses by the architect who founded SCI-Arc.
The architect who founded SCI-Arc designed a house unlike anything else in his portfolio, and then it stayed out of view for nearly fifty years.
The Tempo House at 2941 Briar Knoll Drive in the Hollywood Hills was designed in 1959 by Ray Kappe, the architect who would later found the Southern California Institute of Architecture. Built for Earl and Betty Clemmons and photographed by Julius Shulman, it is one of Kappe's rarest residential commissions, and for most of the last half century it stayed almost entirely out of view.
Most architects are remembered for the buildings they drew. Ray Kappe is remembered for the buildings, the school he founded, and the generations of architects he trained, a story told in full on Debbie Pisaro's profile of Ray Kappe, the architect. The Tempo House is one of the places where that story starts. Debbie writes about the architects and buildings that define California, from Richard Neutra in Brentwood to Gregory Ain in Studio City to the canyon modernists of the Hollywood Hills, and a Kappe belongs in that conversation.
Who was Ray Kappe, and why does he matter?
Ray Kappe, who lived from 1927 to 2019, was one of the most important figures in the history of Los Angeles architecture, significant both for the more than one hundred modernist residences he designed and for founding the Southern California Institute of Architecture in 1972. His influence runs through the buildings he drew and through the school that trained much of the next generation of California architects. His professional papers are held by the Getty Research Institute.
Kappe was born in Minneapolis and graduated with honors from the architecture program at UC Berkeley in 1951. As a teenager in Los Angeles he attended Emerson Middle School, designed by Richard Neutra, an early brush with the architecture he would spend his life advancing. After two years working with Carl Maston, he went out on his own in 1954, and in his first decade he completed dozens of custom post-and-beam houses across Southern California.
His own home in Pacific Palisades, completed in 1967, is widely regarded as one of the most important late-modernist residences in Los Angeles. Built into a spring-crossed hillside in concrete, redwood, and glass, the Kappe Residence is Los Angeles Historic-Cultural Monument 623, and in 2008 an expert panel convened by the Los Angeles Times placed it among the ten best homes in Southern California.
Kappe's reach extends past his buildings. He became founding chairman of the architecture program at Cal Poly Pomona in 1968, then left in 1972 to start SCI-Arc with his wife Shelly Kappe, Thom Mayne, and a small group of faculty, as an alternative to traditional architectural education. He led the school for fifteen years as its founding director. Barbara Bestor, one of the city's most important contemporary architects, earned her Master of Architecture at the school Kappe built from nothing.
The honors followed: the Richard Neutra International Medal for Design Excellence, the AIA California Council Bernard Maybeck Award for Design, the AIA Los Angeles Gold Medal, and the Topaz Medallion, the most prestigious award in American architectural education. Kappe died in November 2019 at the age of 92. The buildings remain, and so does the school.
What is the Tempo House in the Hollywood Hills?
The Tempo House is a 1959 Ray Kappe residence at 2941 Briar Knoll Drive, in a quiet enclave of the Hollywood Hills above the Sunset Strip. Kappe designed it for Earl and Betty Clemmons, which is why the USModernist catalogue records it as the Clemmons Residence, and Julius Shulman photographed it.
The original plan centers on a feature that still defines the house: a round pool beneath an overhead oculus. The principal rooms are arranged to face that focal point, an inward-looking plan that gives the home both privacy and a sense of theater. It is an unusual move for Kappe, whose residential work usually reaches outward along long horizontal lines and post-and-beam transparency. The Tempo House turns inward, organizing its spaces around a single dramatic gesture.
Chuck McCann, the actor, puppeteer, and voice artist, bought the house in the mid-1970s and made it home with his wife Betty Fanning, and it stayed in that household for close to fifty years. By 2000 McCann had brought in the architect Gus Duffy to expand the residence, adding a two-story home theater for screenings and live entertainment along with flexible upper-level space, while keeping Kappe's original design at the center. The Kappe cluster in Debbie's registry also includes the Davis House on Angelo Drive in Beverly Hills, a 1958 commission from the year before.
As expanded, published figures put the house at roughly 3,700 to 4,700 square feet on a lot of about 11,845 square feet, with city, canyon, and hillside views. It was offered for sale in April 2026 for the first time since the mid-1970s and sold in May 2026 for $3,050,000, above its asking price, according to the public record. Debbie Pisaro was not the listing agent for 2941 Briar Knoll Drive. This profile is a registry record of a publicly reported sale and not a representation of any involvement by Debbie Pisaro in the transaction.
What defines Kappe's residential design?
Ray Kappe was an early advocate of what we now call sustainable design, though he would have called it good architecture. His houses were built to work with their climate and site rather than against them, with natural ventilation, passive solar orientation, local materials, and integration with the landscape, decades before any of that became a marketing term. The same instinct, taken to its conclusion, is the subject of Martin Gelber and California's first passive solar house in Brentwood.
His residential work shares a few hallmarks worth knowing. The post-and-beam structure is usually left exposed, so the frame is the aesthetic rather than something hidden behind drywall. Plans step down the hillside instead of flattening it. Glass walls dissolve the line between inside and out. And every house answers its own site, which is exactly what makes a Kappe so hard to compare to anything else. The Tempo House breaks that pattern. It turns the outward-facing language inward, wrapping the plan around its pool.
For buyers of architect-designed homes in the Hollywood Hills, a Kappe original carries weight comparable to a Richard Neutra or a John Lautner. The supply is finite, most owners hold for decades, and the pedigree is documented at the institutional level. The wider modernist landscape is covered in Debbie's overview of Richard Neutra homes in Los Angeles.
What should buyers know about architectural homes in the Hollywood Hills?
The Hollywood Hills hold one of the densest concentrations of architect-designed homes in California, from the Case Study Houses to the canyon residences above the Sunset Strip. For buyers, the challenge is not finding options. It is telling which buildings carry real architectural significance and which are simply nice houses on good lots.
The hillside inventory includes work by Pierre Koenig, whose Stahl House is among the most photographed houses in the world, along with John Lautner, Richard Neutra, and a deep roster of mid-century and contemporary architects. Debbie has profiled several of these homes, including the Flynn Ranch House and the Barragan house in Outpost Estates. The same instinct that reads architecture closely in the Hills also runs through the Eastside, covered in her guide to Los Feliz architecture.
A home designed by Ray Kappe and photographed by Julius Shulman sits at the top tier of that distinction. The pedigree is not a matter of opinion. It is documented. That documentation is also what an honest valuation has to account for, since pricing an architect-designed home depends on the architect, the provenance, and the market for that specific name rather than a generic comp pull, the approach laid out in pricing a one-of-a-kind architectural home.
With architect-designed homes, the name on the plans is part of the value, not a footnote. An automated estimate cannot see a Kappe, a Koenig, or a Neutra. A specialist can.

Frequently asked questions about Ray Kappe and the Tempo House
Who designed the Tempo House in the Hollywood Hills?
Ray Kappe designed the Tempo House at 2941 Briar Knoll Drive in 1959 for Earl and Betty Clemmons, which is why the USModernist catalogue records it as the Clemmons Residence. Julius Shulman photographed it, and the architect Gus Duffy later expanded it for Chuck McCann while keeping Kappe's original design at its center.
Where is the Tempo House?
At 2941 Briar Knoll Drive in the Hollywood Hills, Los Angeles, California 90046, in a quiet enclave above the Sunset Strip near Laurel Canyon. The house sits on a lot of about 11,845 square feet, with city, canyon, and hillside views from the rooms Kappe arranged around its round pool.
What makes the Tempo House different from other Kappe houses?
Most Kappe houses reach outward along long post-and-beam lines and walls of glass. The Tempo House turns inward: its principal rooms face a round pool beneath an overhead oculus. It is an unusual organizing gesture for Kappe, and it is a large part of why the house is so hard to compare to his other work.
Who was Ray Kappe?
Ray Kappe, 1927 to 2019, was an architect and educator who designed more than one hundred modernist residences and founded the Southern California Institute of Architecture in 1972. His honors include the Richard Neutra Medal, the AIA California Maybeck Award, the AIA Los Angeles Gold Medal, and the Topaz Medallion, and his papers are at the Getty.
What is SCI-Arc?
The Southern California Institute of Architecture, SCI-Arc, is one of the most influential architecture schools in the world. Ray Kappe founded it in 1972 with Shelly Kappe, Thom Mayne, and a small group of faculty after leaving the architecture program he had chaired at Cal Poly Pomona, and he directed it for fifteen years.
How often do Ray Kappe homes come to market?
Rarely. Kappe designed a finite number of houses, and owners hold them for decades. The Tempo House stayed with one household from the mid-1970s until it was offered in April 2026, and it sold in May 2026 for $3,050,000, above its asking price, according to the public record.
How much are Ray Kappe homes worth?
Kappe homes vary widely by location, size, and condition, and they rarely come to market because owners tend to hold for decades. His own Pacific Palisades residence, a designated Historic-Cultural Monument, is in a different tier from his smaller commissions. An automated estimate cannot price architectural pedigree, so a specialist valuation is the right starting point.
