LOS ANGELES >> It was midafternoon on a Monday, and Pritzker Prize-winning architect Frank Gehry — despite having just turned 92 in a pandemic, completed the top floor of his building in the Grand Avenue development and prepared for a show of new sculpture at the Gagosian Gallery — had little interest in sitting back to reflect on this potentially meaningful moment in his life and career.

Instead, he was on the move — giving his first studio tour since the COVID-19 outbreak, far more eager to discuss the myriad designs he has underway, most of which have been proceeding. (Only a high-rise in Manhattan’s Hudson Yards stalled, and his office laid off eight of 170 employees as a result.)

Projects include L.A.’s version of New York’s High Line, along the Los Angeles River; new office buildings for Warner Bros. in Burbank; and the scenic design he’s doing for a jazz opera, “Iphigenia,” by Wayne Shorter and Esperanza Spalding, which is heading to the Kennedy Center in Washington in December. Nearly 3,000 miles away, the Philadelphia Museum of Art is set to unveil its Gehry- designed renovation and interior expansion in May (an event the architect plans to attend).

Asked whether, given his age and accomplishments, he has considered taking a break or scaling back, Gehry dismissed the idea.

“What would I do?” he said. “I enjoy this stuff.”

Buzzing through his sprawling work space, the architect said he has reached a point in his career where he has the luxury of focusing on what matters to him most: projects that promote social justice.

“I’m just free,” he said, “now that I don’t have to worry about fees.”

Gehry’s increasing emphasis on giving back seems to have intensified his commitment to this city. He is, for example, designing housing on Wilshire Boulevard for homeless veterans. And about six years ago he and activist Malissa Shriver founded Turnaround Arts: California, a nonprofit that brings arts education to the state’s neediest schools.

“These are labors of love,” Gehry said.

He has volunteered his time in designing a new home for the Los Angeles Philharmonic’s youth- focused educational arm, Youth Orchestra Los Angeles, in the Inglewood Civic Center south of the city, to be completed in June.

Gehry said he was inspired by Venezuela’s publicly financed musical education program, “El Sistema,” which gives underserved children the chance to play in orchestras. A product of that program, Gustavo Dudamel, the music and artistic director of the Los Angeles Philharmonic, who fills the same roles for YOLA, called the Gehry creation “a metaphor that says, ‘Beauty matters.’”

In transforming a 1960s bank building into a concert hall for the youth orchestra, Gehry said he pushed the organization to raise a little extra money to achieve a 45-foot theater, the same size as his Walt Disney Concert Hall.

“It pops up,” he said, “like a lighthouse for the community.”

Gehry — who designed a center for the New World Symphony in Miami as well as the Guggenheim in Bilbao, Spain, and the Guggenheim’s branch planned for Abu Dhabi — remains animated by cultural projects with an educational component (he recently joined the board of the Herbie Hancock Institute of Jazz, a nonprofit organization that trains promising young musicians).

He is perhaps most energized about the River Project — an effort funded by the Los Angeles County Department of Public Works to revitalize the 51-mile channel that runs from Canoga Park to Long Beach and was paved over in 1938 to prevent flooding.

River L.A., a nonprofit group — with the support of Mayor Eric Garcetti — recruited Gehry to develop a master plan for the site. Out of that came the idea for an urban platform park over the concrete with grassy spaces and a $150 million cultural center.

Called the SELA Cultural Center (named after its Southeast Los Angeles location), it will be financed with public and private funds and serve as a space for local artists as well as professionals.

But some have criticized Gehry’s involvement in the project — a public comment period on the plan ended recently — as big-footing community leaders, lacking experience with outdoor space and inviting gentrification.

Gehry has tried to address such concerns and emphasized in an interview that his focus was on creating affordable housing and open space.

“We’re working on social housing opportunities,” Gehry said, “to promote homeownership among the existing population.”

While he can be a lightning rod on the River Project, he is also engaged in more lighthearted pursuits, such as his reinterpretation of the Hennessy X.O bottle for the cognac’s 150th anniversary last year: a crinkled sleeve of 24-carat gold-dipped bronze, encased in sculptural glass.

Inspired by his 5-year-old granddaughter, who calls him “Nano,” Gehry created an oversize “Alice in Wonderland” tea party, complete with a Mad Hatter. That piece, along with colossal vertical fish lamps of polyvinyl and copper suspended from the ceiling, will be featured in Gehry’s sculpture show, opening June 24 at Gagosian’s Beverly Hills space.

“Late in his life, he’s really free to be creative without compromise or collaboration,” said Deborah McLeod, senior director of the gallery. “How much fun this is for Frank Gehry to make whatever he wants.”

While the architect appears slightly more stooped and his hair more wispy, he continues to exude a childlike excitement about design details.

Dressed in a blue T-shirt and brown corduroys, his reading glasses perched atop his head, the architect talked about how much he has enjoyed his give-and-take with Jeffrey Worthe, developer of the Warner Bros. project, for whom Gehry is also designing a hotel complex on Ocean Avenue in Santa Monica.

“He cares about architecture,” Gehry said.

Worthe, for his part, said he has been surprised by Gehry’s openness to input and cost savings.

“He never thinks it’s perfect,” Worthe said, “never thinks he’s got all the answers.”

One project retains a special pride of place: the pair of towers that are part of the King Street development in his native Toronto — the architect’s tallest project to date.

“New York has Rockefeller Center; it’s a coherent architectural piece and it lasts, it holds its own,” Gehry said, adding that he hoped his King Street effort “holds together like that.”

“My grandmother’s street is just up there,” Gehry said, pointing to a rendering on the wall. “My grandfather’s hardware store was here. So I hung out on this street.

“The city gave us extra height,” he added, “because it was me coming home.”
