Hong Kong is among the most densely populated cities in the world, and nowhere is that more apparent than in the city's public housing structures.
However, in his series "Stacked," below, Australian travel photographer Peter Stewart captures the geometric beauty of these buildings.
On one hand, the housing units themselves -- perched neatly on top of one another like Legos -- reach far up into the sky with an almost overwhelming, futuristic vastness. But, on the other, Stewart's images inspire a sense of calm amidst the chaos, by evoking clean, geometric lines and vibrant colors.
