The Jewel Changi will open at Singapore's celebrated Changi Airport on April 17 after reportedly being built for a whopping S$1.7 billion (NZ$1.85 billion).
The marketplace and paradise garden boasts four storeys of lush greenery including the world's tallest indoor waterfall in a feature entitled Forest Valley, along with over 280 retail stores, eateries and an IMAX cinema.
Before its opening, Jewel Changi is offering a ticketed sneak preview from April 11 - 16, which 500,000 members of the public can attend by registering for free online.

The complex has a dome-shaped facade made of glass and steel, and is integrated with Changi Airport's Terminal One. It's also linked to Terminals Two and Three via air-conditioned walkways.
Jewel Changi was designed by Safdie Architects, who describe it as a new prototype for airport design.
"Like an Ancient Greek agora, it aligns social and commercial values to create an animated public realm destination," says Jaron Lubin of Safdie Architects.
Changi Airport has been voted the world's best airport for six consecutive years by Skytrax.
