The Calyx is a purpose-built horticultural exhibition space located within the Royal Botanic Garden Sydney. Its architecture features a circular design centered around a massive green wall, one of the largest in the Southern Hemisphere. The space utilizes a flexible, open-plan layout that undergoes complete thematic transformations for its changing seasonal floral displays. It functions as both a scientific showcase for plant diversity and an interactive educational venue. The facility integrates high-tech environmental controls to sustain rare and exotic species from varying climates. It occupies a site previously used as the garden's former nursery and glasshouse area. The structure is characterized by its light-filled glass walls and sustainable timber framing.
