Architect: Safdie architects
200+ meters : Span of the roof at its widest point.
3,500 tones : Weight of the domed roof.
10 stories : Total number of floors.
38,500M2 : Site area.
134,000 sq m : total gross floor area
1.7 billion : project cost
• created by Safdie Architects, encloses an interactive plaza and marketplace.
• The building shape, based on the geometry of a torus, meets the programmatic need for various connections in an airport context.
• An oculus at the center of the glass roof directs water from a multistory garden five stories down to the forest valley garden at ground level.
• The centerpiece is layered garden attraction that enables guests a spectrum of spatial and interactive experiences.
• Four gateway gardens emphasize the four cardinal directions of north, south, east, and west.
•
The glazed facade dematerializes the structure at night, revealing the illuminating garden within.
01
•
•
A structure that maximized light and transparency in the room was the original "grid shell" concept.
•
The airport rail to run through the project, so the asymmetry of the roof and the displacement of the oculus were designed accordingly.
A steel ring beam encircles the central building. This ring beam evenly distributes the push and vertical forces.
•
The large dome is acting as the airport's new connector and focal point.
•
The garden's durability and ageless appeal served as another strong point.

Structure Form
•
Peering into changi’s jewel
•
The Jewel at Changi Airport supports both membrane forces and out of plane forces that distort the shell.
The inner zone of the toroid, traveling from the interior support columns toward the oculus, acts as a tension cone,
Surface stresses on membranes act in 2 directions: hoop and meridional.
The 12 inch- deep components in this area were designed to buckle.
•
The greatest significant complexity is seen in the region surrounding the intermediate supports.
•
The integration of tension and compression fields pulling and pushing towards the center is resisted by a compression ring zone.
03
•
A shape that represents the structural force patterns within the grid shell roof is produced by the grid shell geometry with various shell depths.
•
A sheer amount of data required the development of the structural system.
•
The team came up with the term "big data" to represent the geometric complexity of the shape.

Triangle panels made of steel and glass.
horizontal hoops are topped with continuous vertical or leaning pieces.
Aesthetic considerations led to the need for larger steel parts as triangle sizes increased.
