Desc: Life on the Rooftop: Directed by Ching-Yao Liao. Taipei is a densely populated city. Sandwiched between the skyscrapers and luxurious apartment blocks, the huts with metal sheeting constructed on the rooftops of old buildings become a dwelling system of its own. These extensions built by the property owners have existed for a long time. They can be seen in the city centre and prime commercial sectors, becoming a unique sight in Taipei's skyline. Often they are referred as the "killer of views" or "tumours of the city".
