Hong Kong isn’t an easy city to navigate. That’s because so much of it exists out of sight: above your head, under your feet, around the corner in a dingy shopping mall. It’s what architect Jonathan Solomon calls a three-dimensional city. “There are all these attempts to map Hong Kong, but most of them are useless,” he says. Maps show streets, others depict shopping malls, but none chart the way Hong Kong’s intricate networks of private and public spaces are linked together by roads, tunnels, footbridges, escalators and lifts. “There’s no record of all the exciting stuff that happens in these spaces.”
Solomon rectifies that situation in Cities Without Ground, an unorthodox guidebook to Hong Kong he published last year with fellow architects Clara Wong and Adam Frampton. Inside its 128 pages is a brief history of Hong Kong’s “condition of groundlessness,” starting with the dramatic, hilly topography that enabled the growth of a vertical city, followed by the popularity of footbridges as a means to connect buildings on different levels and finally the development of vast above- and below-ground pedestrian networks. Most of the book consists not of text but of vivid illustrations dissecting the warren of subways and skybridges, shopping malls and public plazas that make up many parts of Hong Kong.
“There’s an alternative spatial logic in Hong Kong and in order to expose that, we had to reveal something invisible,” says Solomon. “These maps are not meant to be used as wayfinding devices, but I personally find them quite useful as a way of understanding how Hong Kong works.” The maps are as much a document of Hong Kong’s psychogeography as they are of its physical space. Labels include not only the names of buildings and shops, but also human landmarks like “lunching legislators” and the “permanent democracy protest” outside the government headquarters, and “family graduation photoshoots” and a “birdwatching meeting point” in Hong Kong Park.
Cities Without Ground also includes heat maps that chart the range in temperature between different types of buildings: the higher the rents, the frostier the air conditioning. The quality of climate control becomes a quick way to gage the prestige of a given shopping mall. “The network occurs on both the high and the low ends of the economy,” says Solomon. “People talk about Central as one big high-end mall, but if you look at Tsuen Wan, the form is very similar, but it’s all very quotidian middle-class stuff, like hair salons and 7-Eleven and fast food.”
