A giant feather appears to rest atop the check-in hall of the new Terminal 2 at Hong Kong International Airport. Known as the “Feather Roof,” this undulating canopy defines the expansion—designed by Aedas and set to open for departures on May 27, 2026. Supported by columns that resemble tree trunks, the roof modulates the height of the interior spaces while channeling natural light into the heart of the building.
The character of the project is defined above all by the relationship between the roof’s configuration, light and interior spaces, with the aim of making the experience of moving through a complex infrastructure more intuitive and reducing the typical sense of disorientation that characterises many “non-places” of mobility.
The project organises the passenger journey through a clear and intuitive sequence of spaces, guiding them from check-in through security checks to the subsequent boarding stages.
A distinctive feature of the project is the “Feather Roof”, a roof structure resembling a giant feather, composed of elements extending along the east-west axis, which gives the building a sinuous and vaguely organic silhouette. The roof, supported by columns recalling tree trunks, appears to float above the check-in hall, enhancing the sense of openness and lightness. The undulating profile, marked by slopes and troughs, articulates the space below into a succession of areas of varying heights and lighting conditions, helping to visually distinguish the functional zones and guide the flow of travellers.
