Top architects have completed a new Sydney airport with sustainable features and a sculpted ceiling that casts calming, dappled light inside.
COX Architecture, Zaha Hadid Architects, Multiplex, and Woods Bagot teamed up to design Western Sydney International Airport. Although their roles remain unclear, the sleek wood-and-glass exterior echoes Woods Bagot’s style more than Zaha Hadid’s signature curves.
Design Inspired by Nature and Australian Light
The building draws inspiration from the natural landscape, with daylight playing a central role in its design. Its flowing, sculptural ceiling is crafted to mimic the way sunlight filters through eucalyptus bark.
“The ‘Great Australian Light’ was central to our design,” says David Holm of COX Architecture. “We used it to guide movement and mood, creating a calm, clear space that leaves a strong first impression of Australia.”

The project took 9 million work hours and over 2,000 workers. The terminal stretches across 13.5 football fields, with designers prioritizing smooth, intuitive travel.
Energy Efficiency at the Core of the Design
While not fully sustainable, the terminal includes energy-saving features like a low-carbon aluminum ceiling and 8,848 solar panels to cut external power use.
Crews poured 79,500 tonnes of concrete, using an on-site plant to cut truck traffic and fuel use. They also installed a large rainwater tank to supply water for mechanical systems, landscaping, and other needs.
Crews finished the main terminal but are still working on lounges and retail, with the airport set to open in 2026.
