Due to the pressure of housing shortage, container houses have become an emergency choice for municipalities. The cost of expandable container houses is 30% lower than that of traditional buildings, and no foundation construction is required. They are suitable for non-standard plots such as brownfields and parking lots. In 2023, global container house sales will reach 15.4 billion yuan, with the UK accounting for 35% of the European share (leading country), and it is expected to reach 27.08 billion yuan in 2030.
