The contest asked readers to consider the challenges that cities will face over the next century, and to propose innovative solutions for urban homes to overcome those challenges. The competition also asked submitted designs to respond to the MINI Living maxim "big life, small footprint" by making the most of available space in cities.

15 designs from readers based in nine different countries were shortlisted out of over 400 entries from around the world. The final winners will be announced on 17 January 2019, with £10,000 of prizes available: £5,000 for the winner, £3,000 for the runner up and £2,000 for third place.
