Dezeen has announced the 93 projects longlisted for this year's Dezeen Awards in the sustainability categories, including projects by Universal Design Studio, Foster + Partners, Blond and Fletcher Priest Architects.

The 93 longlisted projects, which are in the running for awards in six different sustainability project categories, are by studios located across 28 different countries including Peru, Taiwan, Austria, Israel, Norway and Germany.

The top three represented studio countries are the UK, with 30 longlisted entries, followed by the US and the Netherlands, which are tied with six each.

Amongst the sustainability longlists are a low-carbon community arts space in Uganda, a mass-timber office building in London and a redeveloped brutalist housing estate in Sheffield.

Other longlisted projects include a biomaterial construction block made from a sugarcane by-product, a residential building wrapped in colonnades of tree trunks and a collection of colourful surface tiles made of paper waste.

All Dezeen Awards 2023 longlists revealed this week

Dezeen Awards 2023, in partnership with Bentley Motors, revealed all longlisted projects this week. The architecture, interiors and design longlists were announced earlier this week.

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 the 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 Chitra Vishwanath and Koichi Takada, designers Maurizio Montalti, and Piet Hein Eek.

The judges will determine the projects that feature 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 six winners of the sustainable project categories will then battle to be crowned overall sustainable project of the year.
