The complex and airport is located in Changi, at the eastern end of Singapore, approximately  northeast from Singapore's Downtown Core.

Conception
Jewel was made to maintain Changi Airport's status as a major flying hub in the Asia-Pacific. It was first mentioned by Prime Minister Lee Hsien Loong in his National Day Rally speech in 2013 as part of Changi Airport's long-term plans to double its capacity by the mid-2020s and "create more opportunities for Singapore and Singaporeans".

Built over the former open-air car park in front of Changi Airport Terminal 1, Jewel expanded Terminal 1's arrival hall and baggage claim areas by 70%, and its handling capacity is also expected to increase from 21 to 24 million passengers a year. Jewel was officially opened on 18 October 2019 by Lee Hsien Loong, six months after its soft opening. During this time, it had received 50 million people – about 300,000 people a day – exceeding its initial target of 40-50 million people for the first year.

Jewel was developed by Jewel Changi Airport Trustee Pte Ltd, a partnership between Changi Airport Group (CAG) and CapitaLand, through its own shopping mall business, CapitaLand Mall Asia. The project cost S$1.7 billion, and did not involve any government funds or taxpayers’ money.

Design and development
Jewel's circle glass-and-steel façade was designed by a lot of architects, led by Moshe Safdie, who also designed Singapore's Marina Bay Sands. Renowned local firm RSP Architects Planners & Engineers were the executive architect and structural engineers. The landscape architect was Peter Walker and Partners, who co-designed the National 9/11 Memorial and worked with Safdie on the landscaping of Marina Bay Sands. Benoy were the interior designers; BuroHappold Engineering were responsible for the façade and Lighting Planners Associates handled the lighting. The Rain Vortex was engineered by water design firm WET Design. It has a 360-degree light and sound show projected onto it.

Jewel was imagined to put together a marketplace and an urban park. "The component of the traditional mall is combined with the experience of nature, culture, education and recreation, aiming to provide an uplifting experience. By drawing both people and locals, we aim to create a place where the people of Singapore interact with the people of the world," said Safdie.

The glass panels of the dome are framed in steel which rests on a complex frame. At night, the glowing dome can be seen from all surrounding areas.

Attractions

Shiseido Forest Valley
A partnership of Shiseido and art collective teamLab, the  is one of Asia's largest indoor gardens, spanning five stories and approximately  located in the heart of Jewel Changi Airport. It houses around 3,000 trees and 60,000 smaller plants of 120 different that live in high-altitude tropical forests from around the world.

The Rain Vortex
The Rain Vortex, sponsored as the HSBC Rain Vortex, is the world's largest and tallest indoor waterfall, standing at  high. Recirculating rain water is pumped to the roof to free fall through a round hole at up to  per minute to a basement-level pool. An acrylic funnel at the bottom prevents splashing and insulates the sound of the cascade. The toroid-shaped roof has more than 9,000 pieces of glass spanning  with a sloped oculus as the mouth of the waterfall acting as "a continuation of the building...completed in a liquid form." At night, the circular walls of the waterfall becomes a 360-degree stage for a light-and-sound show.

To prevent excess humidity in the Jewel, the waterfall's flow changes direction often to reduce air turbulence. The design process by WET Design engineers included testing a one-fifth-scale model and a full-size partial sample.

The Changi Airport Skytrain connecting the terminals passes above ground near the waterfall, allowing passengers remaining airside to see the Vortex and Jewel itself.
