The first time Peter Stewart caught sight of Hong Kong, he was at a loss for words. The travel photographer is completely fascinated by the megacity’s verticality and the countless apartments layered on top of each other. “They’re not modern skyscrapers,” he says. “They’re big estates, often made up of seven or eight 100-story towers, all just a few feet apart, almost touching.” Stewart’s works perfectly present these extraordinary living conditions, where individual residences are a rarity, and the norm is a series of modules that repeat in vertical and horizontal layers.
