Season 4

1. Dubai's Dream Palace (Worlds Tallest Hotel)

Megastructures heads to the tiny desert kingdom of Dubai to explore the remarkable engineering behind the seven-star Burj Al-Arab Hotel. Five years in the making, this striking building stands like a gigantic white sail off the shore of Dubai. As this programme reveals, a refusal to compromise on the part of the hotel’s young designers ensured that the project pushed the boundaries of design. The Burj Al-Arab was envisaged by Dubai’s crown prince, Sheikh Mohammed bin Rashid Al Maktoum, as a means of diversifying the country’s economy away from oil into tourism. The Sheikh dreamt of a luxury hotel that would put Dubai on the world map, and surprised many by choosing a relatively inexperienced British firm to supply the design.
