Barbra Streisand has been a collector her entire adult life, and then some. When the sixteen-year-old honors student graduated from Brooklyn’s Erasmus Hall High School and (against the advice of her teachers and her mother) decided to forgo college in favor of acting and singing, she moved to Manhattan and set up housekeeping. Back then, she says, “I had no money to buy art, so I would buy old picture frames and put them on white walls, just framing space, which I thought was beautiful.”

But that was then. Two Academy Awards, two Emmys, a special Tony, eleven Golden Globes, eight Grammys, thirty-seven gold albums, and twenty-one platinum albums (including her latest, Back to Broadway) later, this singer-actress-writer-producer-director-composer can collect anything she wants. And she has amassed enough art, furniture and decorative arts to fill a New York apartment, a house in Beverly Hills, and a compound of five houses in Malibu.

Barbra Streisand goes through collecting phases during which she learns everything possible about a given style or period. As she describes it, such a project is like a movie: “It’s designed as a total vision.” And with collecting, just as with movies, when she finishes one project, she moves on to the next. So to make room for new collections, she must edit what she already has. Moreover, she believes, “If you’re not going to use something, you have to let it pass on, go on its way, and live a life with somebody who will appreciate it.”

Such is the case with Streisand’s collection of Art Deco, which is to be auctioned in March at Christie’s in New York. The collection, which includes a good deal of Lalique glass, an inlaid-ivory desk by Emile-Jacques Ruhlmann, Tamara de Lempicka’s painting Adam et Eve, and clocks by Lalique, Cartier and Cheuret, has been lovingly showcased since the mid-1970s in a guesthouse/poolhouse on the Malibu property, which she meticulously remodeled in the Art Deco style, down to the doorknobs and drawer pulls. She even bought period cars—a 1926 Rolls-Royce and a 1933 Dodge—for its garage.

Streisand is a collector with wide-ranging tastes. At the time she designed the Deco house, she was also buying, among other things, Art Nouveau pieces (stellar examples of which, such as a Tiffany spiderweb lamp and two rare Majorelle corner cupboards, are also included in the Christie’s sale), and the various rooms in her homes reflected this diversity. But for the Deco guesthouse, the challenge was one of “not being eclectic,” she explains. “I thought it would be a really interesting exercise to have one theme.”

So she studied the many books and portfolios that she had gathered on the period, such as Le Luminaire, a portfolio of lighting designs that was published to coincide with the watershed Exposition Internationale des Arts Décoratifs et Industriels Modernes, held in Paris in 1925. She pored over illustrations of decorative motifs, eventually designing several for the house’s architectural details—doors, friezes, and stair rails, ceramic tile patterns, rugs, and even a shower curtain in one of the baths.

The living room fireplace is embellished with a Mondrian-like arrangement of stainless-steel decorative panels that were part of the landmark Art Deco Richfield Building in downtown Los Angeles. The bedroom carpeting was copied from a 1930s Bigelow original that Streisand recalled seeing in the Huntington Hotel in San Francisco. Where original furnishings weren’t used, she had reproductions or interpretations made.

Given that she designed a necklace to harmonize with the house, it’s no wonder that she admires architects like Frank Lloyd Wright, whose approach to design often stretched beyond the house and the furniture in it to dresses for his women clients to wear at home. “If you were an architect,” Streisand argues, “wouldn’t you want to design the bronze handles? Wouldn’t you want to design the floors? Wouldn’t you want to design the furniture that goes into the house you built? That’s the way I see things—as a complete vision.”

Another area in which Streisand set strict limits for herself was that of color. Unable to decide between gray and burgundy for the house’s exterior, she used both—the house is gray on two sides, burgundy on two sides. These colors formed the basis for the interiors, which consist of only two color ranges: black to gray, and burgundy to pale rose. Each room in the house is decorated in a different combination of these two spectrums, and no deviation is allowed: “I don’t put a black vase in the gray-and-burgundy room,” says Streisand. Nor does she put burgundy flowers in the rose bed-room, or pink flowers in the burgundy-and-gray living room. Even the wrappers on the candy in the candy dishes are color-coordinated.

Streisand doesn’t find this narrow range of colors at all confining; in fact, she says, “I like monochromatic rooms, and I like black-and-white movies.” The family photos atop the piano in the living room are black and white—color photos would disturb the harmony. “I like to wear one color; I never wear prints,” Streisand continues. “I think a person sort of fades away in prints.” Still, that didn’t stop her from doing a couple of rooms in prints. She calls the study off the living room her ‘Art Deco Matisse room,” in deference to the artist who so magically juxtaposed pattern on pattern in his paintings. In the room is a Deco sideboard that a previous owner had left out in the rain. Streisand rescued and restored it, and when she decided to use it as a stereo cabinet, she had a pair of speaker cases made. Their carving matches that of the sideboard exactly, and she takes pains to point out how beautifully they are made.

But then craftsmanship is something that Streisand feels passionately about. The house, she says, took nearly five years to complete. “Doing this took me almost a year,” she sighs, pointing to one of a pair of elegant gray silk tassels that hang from the silk-rope handrail in the stairway. Craftsmanship is also the main reason she loves old things. “Where could you buy shoes like this?” she asks, reaching for a pair of 1920s pink satin evening slippers, part of the wardrobe of vintage clothing that fills the house’s closets (color-coordinated with each room, of course).

Barbra Streisand began to collect vintage clothes as an aspiring actress because she couldn’t afford new ones, but she never stopped appreciating their quality. In another closet, Streisand pulls out an ancient, honey-colored coat of karakul with fox trim, for which she paid ten dollars at a thrift shop. “I went to audition for I Can Get It for You Wholesale in that,” she remembers. (The rest is history, and Streisand later had the coat copied exactly, but in white, for her role in Funny Girl on Broadway.) “Look at that embroidery,” she says, showing off the lining. “It’s a wonderful metaphor for life, isn’t it? That something should be as beautiful on the inside as it is on the outside—maybe even more beautiful.”

But, as this tireless collector is fond of saying, “I like the idea of evolution and change.” Having focused on American Arts and Crafts furniture, folk art, Pairpoint lamps, and paintings by Thomas Hart Benton and Edward Hopper, Streisand now says, “This time I’m moving back in history—I’m fascinated by eighteenth-century America.” Between study trips to places like Winterthur and Monticello (which inspired her to repaint her Beverly Hills dining room a deep, rich ivory), Streisand is buying everything from primitive paintings and furniture to eighteenth-century American interpretations of Chippendale and Queen Anne.

To make her vision of Americana complete, Streisand would love to build a new house, “with a lot of porches” and perhaps a grand stair hall, inspired by the historic Colonial and southern houses that she has seen in her travels. However, on top of her new contract with Sony to record six albums and make new films, including an adaptation of Larry Kramer’s play The Normal Heart, building a new house may be too much for one person to handle. Then again, Barbra Streisand has only to recall the tagline of her film Yentl (one of the few movies that a woman co-wrote, produced, directed, and starred in): “Nothing’s impossible.”
