ICC

Architecture & Design

Standing at 484 meters, the International Commerce Centre (ICC) is the tallest building in Hong Kong. Completed in 2010 and designed jointly by Kohn Pedersen Fox Associates and local firm Wong & Ouyang, the tower rises 108 floors and is clad in a double-glazed curtain wall engineered to cut heat gain while keeping the facade transparent. The structural core is reinforced concrete, built to withstand the region’s typhoon wind loads, and the tower’s tapered silhouette — narrowing gradually as it climbs — is a direct response to that same wind-load problem rather than a purely aesthetic choice, reducing vortex shedding at a height where a uniform rectangular profile would create dangerous resonance.

History & Economic Context

The ICC anchors Union Square, a large reclamation project on the West Kowloon waterfront developed jointly by Sun Hung Kai Properties and the MTR Corporation atop the corporation’s own Kowloon Station railway depot — a common Hong Kong development model where the transit operator trades development rights above its infrastructure for construction capital. Site development began in 2002, with the tower reaching its structural topping-out in 2009 at an overall project cost estimated in the tens of billions of Hong Kong dollars across the full Union Square package. The completed tower functions as a vertical mixed-use city: grade-A office floors, the Ritz-Carlton hotel occupying the upper levels, and the Sky100 observation deck, which opened to the public on April 17, 2011, on the building’s 100th floor. From that vantage point, sightlines run clear across Victoria Harbour toward Central and the ridgeline of Hong Kong Island — the same view corridor SHKP has since tried to extend commercially, having won the tender for the commercial site above the West Kowloon High-Speed Rail Terminus in 2019.

Local Taste & Skyline Context

The tower’s ground-level connection to Elements mall means most visitors experience the ICC first as a shopping and dining destination before ever reaching the elevators to Sky100 — the observation deck ticket line and the mall’s luxury retail concourse sit within the same integrated podium, a layout SHKP has repeated at other Union Square-style developments since. For a plainer meal with a harbour view instead of a mall-brand one, the promenade running along the Kowloon waterfront just outside the tower offers unobstructed sightlines toward Hong Kong Island without an admission ticket at all, making it a common lower-cost alternative to Sky100 for visitors who want the view without the fee. The ICC’s own record as Hong Kong’s tallest building has held since 2010, a longer unbroken run at the top than the two previous record-holders, Central Plaza and the Bank of China Tower, each managed before being surpassed in turn — a reflection of how few sites in the territory now offer both the land area and unobstructed air rights needed to build past 400 meters.

Practical Information

The building connects directly into the MTR system via Kowloon Station. Passengers arriving on the Tung Chung Line or the Airport Express reach the complex through an underground pedestrian network. For food before or after ascending the tower, the neighboring Elements mall offers upscale dining, while a ten-minute walk toward Jordan leads to dai pai dong-style stalls serving stir-fried beef noodles and milk tea — a plainer, street-level contrast to the tower’s polished glass interior. The Sky100 deck operates daily, with access via high-speed double-decker elevators that reach the 100th floor in roughly 60 seconds.
