Conceptual Form & Structural Idea
Case Study1
Design Inspiration: The Hymenocallis flower (desert lily); tripartite Y-shaped
geometry.
The tower tapers upward in setbacks, reducing wind load and increasing stability. BURJ

pushed up to the sky. at the joints, eliminated the reinforcing
bar congestion issues, and most
importantly ensuring the joint integrity.
