Houston Grand Opera, which was driven from its opera house by the flooding unleashed by Hurricane Harvey, said on Monday that it had found a temporary home for the first three productions of the season: Exhibit Hall A3 of the city’s George R. Brown Convention Center, which sheltered hundreds of Texans during the storm.

The company is calling it “the HGO Resilience Theater.”

Moving opera productions — with their large casts, choruses, full orchestra, elaborate costumes and imposing scenery — to a new space on short notice will require some resiliency. But the company was left with little choice after its regular home, the Wortham Theater Center, was flooded with 12 feet of water by the hurricane, causing enough damage that it will likely remain closed until at least May. So the company will open its season on Oct. 20 with Verdi’s “La Traviata” at the convention center, followed by Handel’s “Julius Caesar” and the world premiere of Ricky Ian Gordon and Royce Vavrek’s “The House without a Christmas Tree.”

Houston is working to make a virtue of necessity, noting the recent vogue for presenting operas in offbeat spaces including factories, lofts, museums and bus depots.

“We will use the space to defy normal operatic convention to present what I call ‘unconventional opera,’ ” Perryn Leech, the company’s managing director, said in a statement. “This will be a jewel of a performance space, with tremendous versatility. Having worked extensively with temporary and site-specific venues, I think our audiences will be amazed at the kind of direct and immersive theatrical experience we can create for them.”
