More than a dozen food, retail or office complexes made from shipping containers have opened across Britain within the past three years.
The figures, from research by Radio 4’s You and Yours programme, demonstrate the growing popularity of so-called container communities.
Organisers say they provide a stepping stone for small businesses before they move to bigger premises.
Some of the sites offer city centre locations but are only temporary.
Rents for space inside converted containers are relatively cheap and sites have opened in cities including Manchester, Bristol, Cardiff, Edinburgh and York with others planned for Liverpool and Norwich.
