Rooftop houses are usually found in Hong Kong's old urban areas such as Sham Shui Po, Yau Ma Tei and Kwun Tong. These structures hailing from the 1950s that made room for the influx of immigrants still remain, even though it is illegal to construct additional structures on top of buildings.

Rooftop houses boast an unrestricted panoramic view of the Hong Kong skyline.

Built on top of an industrial building in Kwun Tong, these rooftop slums are usually built from wood, rusty metal sheets or other flimsy materials.
