At 250 feet long and 60 feet tall, the Botanical Building in San Diego is one of the largest lath structures in the world. Since its construction for the 1915 Panama-California Exposition, it has served as a plant-filled fixture of Balboa Park. But after decades of weather exposure, the building’s hundreds of redwood lath strips and original steel frame were deteriorating. Advocacy by nonprofit Forever Balboa Park led to an infusion of state funding for its restoration in 2019, and the 15,000-square-foot structure reopened to the public in December 2024.
