The Design-History

Architect, Adrian Smith, has said

the triple-lobed footprint (base) of

the building was inspired by the

flowerHymenocallis

The design of Burj Khalifa isderived from patterning systems

embodied in Islamic architecture.

According to the structural

engineer, Bill Baker, the building's

design contains cultural and

historical elements particular to the

region.

The Y-shaped plan is ideal for

residential and hotel usage, with the

wings allowing maximum outward

views and inward natural light
