Congratulations to the winners! Alexandru Patrichi from Belgium, Alex Lister from Scotland, Antoine Chatiliez from France, Zuzana Pavlaninova from Netherlands and Nina Farrall from England.
The awards, which are held annually by the museum, celebrate design that "promotes or delivers change, extends design practice or captures the spirit of the year".
The exhibition shows the work of 76 designers across six categories including architecture, digital, fashion, graphics, product and transport design.
Other projects nominated for the Design of the Year title include Google's self-driving car, a building material made from mushrooms and a shock-absorbing wheel for wheelchairs and bicycles. A full list of the nominees can be seen here.
Five winners will each receive a pair of tickets for the show, which will be on display at the museum until the 23 August.
This competition is now closed. Winners will be selected at random and notified by email. Winners' names will be published in a future edition of our Dezeen Mail newsletter and at the top of this page. Dezeen competitions are international and entries are accepted from readers in any country.
