Mill Junction Student Housing (Johannesburg, South Africa) 

The developers at Citiq decided to one-up anybody reclaiming and reusing building material by fashioning an 11-story dorm out of shipping containers and abandoned grain silos. This colorful space near the city’s central business district accommodates nearly 400 students in a mish-mash of metal shapes.
