The project named Urban Rigger aims to provide low-cost housing for students in the centre of the Copenhagen, docked in the harbour.
BIG's scheme comprises nine shipping containers stacked and arranged on a floating base, to create 15 studio residences over two levels.
The blocks are angled with their ends overlapping to frame a shared garden in the centre of the mobile platform – also intended to protect the housing from the threat of rising sea levels.
"In terms of sea level rise... it's the only building type that will never flood," wrote BIG partner Kai-Uwe Bergmann on his Facebook page.
The containers are connected by glazed greenhouse-like spaces. Windows and doors are punched in the ends and flanks of the corrugated metal blocks, which are painted bright aquamarine.
The flat roofs of the three containers forming the upper floor each have a different function. One provides a terrace, another hosts solar panels and the final roof is covered in grass.
Urban Rigger is the latest addition to a string of proposals considering shipping containers as a model for affordable housing. One recent concept proposes a skyscraper of stacked units designed to replace slum housing.
"There are few strategies that allow cities to expand. Yet, Copenhagen's harbour remains an under-utilised and underdeveloped area at the heart of the city," said the studio.
"By introducing a building typology optimised for harbour cities we can introduce a housing solution that will keep students at the heart of the city."
Copenhagen's harbour area is currently undergoing significant redevelopment. Local firm COBE is currently redeveloping an artificial island in the harbour to create arts spaces and housing, and American architect Steven Holl has proposed a pair of skyscrapers linked by an aerial bridge at its mouth.
