I always find it a pleasure to land back on Cambodian soil after a trip away, but Phnom Penh’s stunning new airport has lent an added frisson of pride to the experience. Since its launch in September 2025, on a 2,600 hectare site some 25km outside the city centre, the new, world-class Techo International Airport (KTI) has been receiving global acclaim for its spectacular architectural design courtesy of award-winning British architects Foster + Partners.

And it really is a spectacle: a series of sculptural, interlocking domes with a lattice-effect resembling traditional Khmer basketwork, framing a vast, open plan terminal with towering native trees and a 30ft gilded Buddha statue. With its emphasis on natural light and airflow, the structure borrows from traditional Cambodian building design with a respectful nod to the iconic New Khmer Architecture of the country’s Golden Age. The vaulted ceilings — rising to heights of up to 42 meters — with myriad tiny skylights very effectively reduce the need for artificial lighting and air conditioning. Sustainability was high on Foster + Partners’ agenda and the development’s impressive eco credentials also include the use of solar power, rainwater harvesting, and lush tropical planting to improve the air quality.
