Tricia Beanum reclines on a vintage Mies van der Rohe MR lounge chair inside Pop Up Home and surveys her recent estate sale finds: vintage Persian rugs, midcentury pottery, a brass and glass Milo Baughman étagère.

Across the aisle of the warehouse-turned-showroom, Beanum has priced a Sergio Rodrigues Kilin lounge chair and a 1970s-era Barzilay wall unit far less than similar listings on 1stdibs, the online antiques market.

“I found the wall unit deep in the Valley inside a home in Northridge,” she says. “I’m a hunter. I’m inspired by what people collect.”

She started the Estate Sale Company Los Angeles in 2006 after hosting a few small liquidations. A shrewd and relentless hunter in a male-dominated business — she went into labor at the Rose Bowl Flea Market — she was soon cold-calling Lawson Fenning and Nickey Kehoe with her son and vintage picks in the back seat of her car.

Today she spends the majority of her time “digging through homes” and staging estate sales in homes throughout Los Angeles (she receives 40% of the profits). “I love the picking and finding,” she says. “I have dug through moldy interiors to find things.” She also hosts occasional pop-up sales, including a forthcoming sale of small goods at Gjusta in Venice on June 7-30.

Los Angeles residents are a discerning group when it comes to thrifting, so it’s not surprising that Beanum’s estate sales, combined with her penchant for deals, have earned her a following with set decorators, interior designers and celebrities including Joni Mitchell (“I cried when I met her,” she says), Paula Abdul and Pamela Anderson.

And in a world where environmentally conscious consumers often prefer vintage fashion and furnishings to brand new goods, Beanum offers an opportunity to create distinctive interiors while following the “reuse, reduce, recycle” mantra.

“I never buy anything new, with the exception of clothing and mattresses,” said Beanum, who is 43. “There’s too much stuff in the world. I don’t like waste. Don’t buy retail. You don’t have to.”

As her estate sale business has taken off — a Gucci-filled one-bedroom apartment in Beverly Hills brought in more than $60,000 — so has her retail presence.

A few years ago, Beanum decided to open her West Adams storage warehouse to the public. Originally open once a month, it is now open year-round on Wednesdays through Sundays. “Pop Up Home is like my version of Dickens’ Old Curiosity Shop,” said interior designer Bryan Wark. “Tricia curates some of the most wonderful objects. Her warehouse is always full of incredible finds. Many of the city’s very high-end dealers go to Tricia for things for their own shops.”

Indeed, Beanum’s eye for unique furnishings is evident from the moment you walk into the showroom, with its charismatic blend of designer furniture, found objects and works of art. At Pop Up Home, Pierre Cardin side tables mix with Murano glass mushroom lamps, Knoll classics and Playboy magazines from the 1970s that are priced to sell at $10 apiece. “You always find them in boxes,” she said. “Always.”

Everything, in fact, is priced to sell, which means the black leather Wasily chairs you spotted on a recent visit are gone the next week. Asked if she makes deals, Beanum doesn’t hesitate: “All the time. Especially if you catch me on a good day.” She accepts some items on consignment and receives tips from pickers and real estate agents all the time. “I just want to turn stuff and make people feel like they got a good deal,” she said. “It’s so much fun for me to see people buying nice things for their first home.”

Beanum says she hopes to have a warehouse “three times the size” of her current showroom one day, but until then, she takes pride in the fact she has created her own niche, a hip Los Angeles phenomenon fueled by the “cool stuff” of others.

“It’s about the collection of things,” she explained. “I buy what I like — anything Italian, lamps, ceramics, barware, portraits of women — especially if I can tell a story with it.”

It is the storytelling, she says, that people find so compelling. “It’s always the first question people ask me when they buy something,” she says of her return customers. “ ‘Where did you find this?’ ”
