IIt is common in Karachi to install small or medium sized awnings to shade shop fronts, restau- rant terraces, political or religious meetings and mobile commerce units like trolleys. In some dense areas like bazaars it becomes a main part of the urban landscape. Since this is a cheap technology everybody adapts it and finds creative solutions for joins, anchorages, drainage... Over time successful solutions are copied. The result is an extremely refined and simple con- struction solution.
