World’s Tallest Indoor Waterfall in Pictures


Safdie Architects complete world’s tallest indoor waterfall at Jewel Changi Airport in Singapore

An indoor forest sits under a large glazed dome with a rainwater waterfall running through the middle at Singapore’s Jewel Changi Airport by Safdie Architects.

Safdie Architects led a consortium of architects and designers to build the five-storey plant-filled greenhouse filled with shops and public spaces, which opens to the public.

Thousands of people flock to a new extension of Singapore’s Changi Airport, to see the world’s tallest indoor waterfall.

The Rain Vortex is seven storeys tall, and pumps 500,000 litres of rainwater through the roof of the Jewel building – that’s a fifth of the volume of an Olympic-sized swimming pool.

The glass bagel-shaped building is connected to the city’s transport systems and directly to airport terminal one, as well as terminals two and three via pedestrian bridges.

“The Jewel toroidal inverse dome creates a new kind of spatial experience, a daylit vast landscaped garden, combined with seven levels of shopping and airport facilities,” said Moshe Safdie, founder and principal of Safdie Architects.

“Light penetrates everywhere, while the roof drains through the dome to create a dramatic waterfall, dropping seven storeys to the lowest building level.”

On the fifth floor another garden called Canopy Park is filled with attractions such as nets and slides.

Fourteen tree-like columns and a ring beam support the domed roof, which is formed of a continuous grid shell supporting panes of high-performance glass.

This glass is designed to maximise the light that reaches the building while preventing it from getting too hot inside, to ensure that the plants have the ideal conditions to grow in.
