I see Hong Kong as a model of smart growth management and land use planning. It’s a city were policy dictates that development must concentrate on only 25% of the land area, with the remaining 75% preserved as open space. This policy ensures that the region’s lush green spaces remain intact. It also maintains scarcity and high land values in developable areas. This is crucial to the local government because its primary source of income is land leasing.

Looking at development in Hong Kong through Western eyes, I noticed another impact of the city’s tightly concentrated density: the compact clustering of residential and working populations supports a diverse, competitive, and often ingenious retail community.

My first up-close encounter with the retail streetscape occurred in Tsim Sha Tsui, an upscale neighborhood on the Kowloon side of Victoria Harbor (map). What struck me most was the extreme permeability at the pedestrian level. Few storefronts at the ground floor, save a handful of banks and higher-end boutiques, have full walls. Separated from the sidewalk by only a few inches of floor height, merchants do business in cheerful cubicle-sized spaces under fluorescent lights while people flow past, around, in and out.

At the newly unveiled Web site Shape Vancouver 2050, users are given a digital model of the Vancouver skyline, the ability to extrude buildings upwards, and a visual gauge of the resulting effects on the city’s downtown. As the user drags the digital towers higher and population density increases, meters at the bottom of the screen go up too—energy saved, carbon use curbed, dollars added to the city coffers.

It’s a neat tool, if a bit of a one-liner: the more tall buildings you insert, the better things get; make nearly all the buildings tall and you’ve created an “Urban Paradise!” (Leave most of the buildings as low-rises and you’re chided for fostering sprawl.) It’s not entirely clear whether the site’s creators—the architecture firm Perkins +Will and the developer Concord Pacific—intended Shape Vancouver as an honest solicitation of planning input from the public, or a sneaky way to educate (or indoctrinate?) residents in the environmental benefits of high density. Either way, their message is clear: Want a better Vancouver? Build tall.
