Does anyone know about the Ceylon Pavilion at the 1924 British Empire Exhibition in Wembley?

I recently learned that my friend’s great-grandfather helped design the Ceylon Pavilion at the 1924 British Empire Exhibition in Wembley, London. It was reportedly modeled on Kandy architecture and was opened by King George V. I’ve seen references to commemorative medals, but I can’t find solid info online about whether the pavilion won a gold medal or if any part of it still exists today. Does anyone have historical sources, photos, or insights on what happened to the Ceylon Pavilion after the exhibition?
