The Case Study houses that made Los Angeles a modernist mecca

Mapping the homes that helped to define an era

View as Map

Los Angeles is full of fantastic residential architecture styles, from Spanish Colonial Revival to Streamline Moderne. But the modernist Case Study Houses, sponsored by Arts & Architecture and designed between the 1940s and 1960s, are both native to Southern California and particularly emblematic of the region.

The Case Study series showcased homes commissioned by the magazine and designed by some of the most influential designers and architects of the era, including Charles and Ray Eames, Richard Neutra, and Pierre Koenig. The residences were intended to be relatively affordable, replicable houses for post-World War II family living, with an emphasis on “new materials and new techniques in house construction,” as the magazine’s program intro put it.

Technological innovation and practical, economical design features were emphasized—though the homes’ scintillating locations, on roomy lots in neighborhoods like Pacific Palisades and the Hollywood Hills, gave them a luxurious allure.

With the help of photographer Julius Shulman, who shot most of the homes, the most impressive of the homes came to represent not only new styles of home design, but the postwar lifestyle of the booming Southern California region.

A total of 36 houses and apartment buildings were commissioned; a couple dozen were built, and about 20 still stand in the greater Los Angeles area (there’s also one in Northern California, a set near San Diego, and a small apartment complex in Phoenix). Some have been remodeled, but others have been well preserved. Eleven were added to the National Register of Historic Places in 2013.

Here’s a guide to all the houses left to see—but keep in mind that, true to LA form, most are still private residences. The Eames and Stahl houses, two of the most famous Case Study Houses, are regularly open to visitors.

As for the unconventional house numbering, post-1962 A&A publisher David Travers writes that the explanation is “inexplicable, locked in the past.”

J.R. Davidson (with Greta Davidson) designed this house in 1948 (it was actually his second go at Case Study House No. 1). It was intended for “a hypothetical family" with two working parents and was designed to require "minimum maintenance.”

Legendary designer couple Charles and Ray Eames designed the Eames House in 1949 and even Arts & Architecture seemed kind of blown away by it. The home is built into a hillside behind a row of Eucalyptus trees on a bluff above Pacific Palisades. It's recognizable by its bright blue, red, and yellow panels. The Eameses lived in the house until their deaths. It’s now open to visitors five days per week, though reservations are required.

Designed by J.R. Davidson in 1947, Case Study House No. 15 has south walls made of huge glass panels. Its flagstone patio and indoor floor are at the same level for that seamless indoor-outdoor feel. According to the magazine, the floorplan “is basically that of another Davidson house, Case Study House No. 11,” which has been demolished.

Craig Ellwood’s Case Study House for 1953 is usually numbered as 16 in the Case Study series. It has a modular steel structure and “the basic plan is a four-foot modular rectangle.” But the interior walls stick out past the exterior walls to bring the indoors out and the outdoors in. The Bel Air house hit the market in November with a $3 million price tag.

Case Study House No. 17 (A) was designed by Rodney Walker in 1947. A tight budget kept the house at just 1,560 square feet, “but more space was gained through the use of many glass areas.” The house also has a large front terrace with a fireplace that connects the indoor living room fireplace. The house has been remodeled.

Case Study House No. 17 (B) was designed in 1956 by Craig Ellwood, but “governed by a specific program set forth by the client.” Ellwood took into account the clients' collection of contemporary paintings and made the living room “purposely undersized” to work best for small gatherings. The house was extensively remodeled in the sixties by Hollywood Regency architect John Elgin Woolf and his partner, interior designer Robert Koch Woolf.

Case Study House No. 18 (A) was designed by Rodney Walker in 1948. The house is oriented toward the ocean, but set back from the cliff edge it sits on to avoid noise issues. As A&A says, "High above the ocean, the privacy of the open south and east exposures of Case Study House No. 18 can be threatened only by an occasional sea-gull." The house features a "bricked garden room" separated from the living room by a two-sided fireplace.

Case Study House No. 18 (B) was designed by Craig Ellwood in 1958. Ellwood didn’t attempt to hide that the house was prefabricated (the magazine explains that he believed “that the increasing cost of labor and the decline of the craftsman will within not too many years force a complete mechanization of residential construction methods”). The components of the house, however, are “strongly defined with color: ceiling and panels are off-white and the steel framework is blue.” According to A&A's website, the house has been remodeled.

The Bass House was designed in 1958 by Buff, Straub, and Hensman for famed graphic designer Saul Bass. It's “unique in that it was based upon the experimental use of several prefabricated Douglas fir plywood products as part of the structural concept,” including hollow-core plywood vaults that covered the central part of the house.

Pierre Koenig's Stahl House, designed in 1960, is probably the most famous house in Los Angeles, thanks to an iconic photo by Julius Shulman. The house isn't much to look at from the street, but its backside is mostly glass surrounding a cliff's-edge pool. Tours are available Mondays, Wednesdays, and Friday—but book well ahead of time, as they sell out quickly.

The unnumbered Case Study House for 1950 was designed by Raphael Soriano. It's rectangular, with living room and bedrooms facing out to the view. However, in the kitchen and eating areas, the house “turns upon itself and living develops around a large kitchen-dining plan opening upon a terrace which leads directly into the living room interrupted only by the mass of two fireplaces.” According to A&A's website, the house has been remodeled.
