Burj Khalifa: A Vertical City—Residential, Commercial, Hotel, Observatory, Mall

The Burj Khalifa (828 m, 163 floors) is not just a skyscraper; it’s a mixed‑use megastructure designed as a “vertical city.” Its functions include:

• Residential: “The Residences” – luxury apartments and penthouses (floors 19–108).
• Commercial: Corporate suites and offices (floors 112–154).
• Hospitality: Armani Hotel Dubai (floors 1–8, 38–39).
• Observatories: “At the Top” (124/125) and “At the Top SKY” (148) – world’s highest observation decks.
• Retail & Entertainment: Connected to The Dubai Mall (aquarium, ice rink, 1,200+ shops).
• Symbolic: Embodies Dubai’s ambition, innovation, and global status.

By integrating living, working, leisure, and tourism, Burj Khalifa redefines high‑density urban development.
