Should I have heard of him? Maybe. In 2000, style magazine Wallpaper listed his firm, Edge, in its 'Smart Set' top-20 ranking of with-it architects around the globe. At the same time, the glossy assessed his fame quotient as low. What's his story? Born in Happy Valley in 1962, Chang graduated from the Department of Architecture at the University of Hong Kong in 1987 and co-founded Edge in 1994. Four years later, he went solo, forming Edge (HK), which was originally housed in the sprawling Oil Street complex in North Point. Chang had to move to comparatively modest premises at the end of 1999, but since then has moved to offices with sea views in Quarry Bay. He was also among the first group of Hongkongers invited to take part in the Venice Biennale, in 2000 and 2002. What is he known for? The Suitcase House in Beijing at the Commune (a group of houses designed by 12 of Asia's best-known architects, such as Japan's Shigeru Ban and Taiwan's Chien Hsueh-yi by the Great Wall. Is the Suitcase House portable? You can't quite fold it up, tuck it under your arm and take it on the MTR. Even so, it is a touch more malleable than the average home. MCM, the publisher of the book The Suitcase House, describes the oddity as an 'uncanny prototype' and 'pop-up book meets designer living'. The Suitcase House tries 'to rethink the nature of intimacy, privacy, spontaneity and flexibility'. What does it consist of? Three layers and an array of devices: sliding partitions, folding doors and pneumatic floor panels that rise to expose hidden compartments. As a result, you can tailor the 250-square-metre structure to your living requirements and entertainment whims. When visitors come to the Suitcase House, they laugh and treat the place like a mechanical theatre. But the establishment takes the Suitcase House seriously. Last year, it won a Design for Asia Award. The judges said it 'breaks the mundane rituals of everyday life, arousing public interest and rethinking the use of limited space with maximum flexibility'. What inspired it? His crowded upbringing. 'When you need something, it appears, and when you don't, it disappears,' Chang has been quoted as saying. What else has he done that demands attention? Arthouse cinema Broadway Cinematheque, the Mega-iAdvantage internet service centre in Chai Wan and the Hong Kong Arts Centre's atrium. He also designed Leisure Slice (below) outside the Hong Kong Arts Centre. Does he just do installations and buildings? No. He is also responsible for miniature marvels such as the Kung Fu Tea Set, which is produced by Alessi. Where can I see more of his work? The Edge Design Institute, suite 1604, Eastern Harbour Centre, 28 Hoi Chak Street, Quarry Bay, tel: 2802 6212.
