All Dezeen Awards 2023 longlists revealed this week

Dezeen Awards 2023, in partnership with Bentley Motors, will reveal all longlisted projects this week. The interior longlist will be announced tomorrow, followed by the design longlist on Wednesday and the sustainability longlist on Thursday.

Longlisted projects have been selected from over 4,800 entries from 94 countries for the sixth edition of our awards programme, which celebrates the world's best architecture, interiors and design, as well as studios and individuals producing the most outstanding work.

The next stage of Dezeen Awards 2023 will see all longlisted projects assessed by our international jury of leading professionals including architects Farshid Moussavi, Thom Mayne, Lara Lesmes and Omar Gandhi.

The judges will determine the projects on the shortlists, which will be announced in October. A further round of judging by our master jury will determine the winners, which will be announced in November.

The 15 winners of the architecture project categories will then compete to be crowned overall architecture project of the year.
