This mobile multi-storey structure, piloted in Antwerp and Copenhagen, has capacity for several tents on each of its ovalshaped levels, offering impressive views of the city for those on a tight budget. The structure also has the advantage of a small footprint and doesn’t congest thoroughfares. This might make local authorities more favourably inclined to backpackers.

This and more inspiring projects can be found in the print copy of A smart guide to Utopia or the ebook version.
