12 meter long shipping containers, to create a large viewing deck and a VIP lounge area, to substitute the typical grand stand scaffolding structure at the Voodoo Music Experience, New Orleans. The containers also double as storage space for other festival components throughout the year. The two top containers are cantilevered 2.7 meters on each side, creating two balconies that are prime viewing locations. There were also two bars located on the balconies. Each container was perforated with cutouts spelling the word "VOODOO," which brands the structure, and creates different vantage points and service area openings. Since the openings themselves act as signage for the event, no additional materials or energy were needed to create banners or posters. In the United Kingdom, walls of containers filled with sand have been used as giant sandbags, to protect against the risk of flying debris from exploding ceramic insulators in electricity substations. In October 2013, two barges owned by Google with superstructures made out of shipping containers received media attention, speculating about their purpose.

In Central Asia, the Dordoy Bazaar in Bishkek, Kyrgyzstan, almost entirely composed of double-stacked containers, is of comparable size. It is popular with travelers coming from Kazakhstan and Russia, to take advantage of the cheap prices and plethora of knock-off designers.
