A little search brought me to Keetwonen, a student housing project in Amsterdam by a company called TempoHousing:
Keetwonen, a student housing project in Amsterdam, turns shipping containers into 1000 units and provides all the amenities a student could ever want. And aside from the obvious green usage of surplus shipping containers, Keetwonen has integrated a rooftop to accommodate efficient rainwater drainage while providing heat dispersal and insulation for the containers beneath. [...]
Containers are home to not only the 1000 units that each have a private balcony, but a cafe, supermarket, office space, and even a sports area. Units are arranged in “blocks,” each block containing a service unit with centralized electricity, internet, and networking systems.
