This week on Dezeen, we held the inaugural Dezeen Day conference and the overall winners of the Dezeen Awards 2019 were revealed at our party in London.

On Wednesday 30 October, we launched our international architecture and design conference at London's BFI Southbank, which saw industry leaders come together to discuss key topics like the circular economy, future cities and education.

MoMA curator Paola Antonelli kicked off the event with a keynote presentation in which she drew attention to the climate crisis, and told delegates that anger is a better catalyst than angst for designing a better future.

Other highlights included architect and film director Liam Young advising architects to design video games, and brand consultant Suzanne Livingston stating that humans will be replaced by artificial intelligence during a panel about future cities.

In a discussion about the circular economy, Dutch designer Richard Hutten clashed with fellow panellist Andrew Morlet, CEO of the Ellen MacArthur Foundation, over whether there is a place for plastic in the circular economy. Hutten also said that he "will never design in plastic again".

The Dezeen Awards 2019 party also took place on Wednesday, during which the category winners received their trophies and we revealed the best overall projects.

Architecture project of the year was awarded to Studio Tom Emerson and Taller 5, while the best design and interiors projects were won by Mediated Matter Group at MIT and Branch Studio Architects respectively.

During the party held in London's Ennismore Sessions House, Vo Trong Nghia Architects, SevilPeach and Studio Drift were also named as this year's best architecture, interiors and design studios.

Meanwhile, the awards for the emerging studios of the year were given to Edition Office, Linehouse and Takt Project – picked from a shortlist of 17 emerging studios.

Elsewhere, Zaha Hadid Architects revealed its competition-winning proposal for an airport this week, which it has designed for a greenfield site in Sydney with Cox Architecture.

Dezeen reported on Carmody Groarke's design for an extension to the Design Museum Gent, which is hoped to improve circulation between its existing galleries.

In the US, BIG completed a school building in Virginia named The Heights. It is distinguished by its twisting form that creates a series of "cascading terraces".

Coldefy & Associés and RDAI won a competition to build a museum and memorial dedicated to the 2016 Pulse nightclub shooting in Orlando.

Sustainable design remained in the spotlight as The Ocean Cleanup launched the Interceptor, a system to catch plastic waste in rivers before it reaches the sea.

Meanwhile, students from Cambridge University hit the headlines after building an ultra-efficient electric car that drives using only as much power as it takes to boil a kettle.

Other projects enjoyed by readers this week included a funeral parlour designed to have "the eclectic feel of home", a timber holiday home in New Zealand's mountains, and the colourful renovation of a fire-damaged Klinker Apartment in Barcelona.
