Congratulations to the winners! Matthieu Sago in France, Jane Hakes in England, Rebeka Babič in Croatia, Balwant Ram in India and François Gaboury in Canada. They all receive a copy of Radical Cities.
Radical Cities sees McGuirk journey across Latin America to meet architects, activists and politicians, to find out how cities are evolving in countries including Brazil, Venezuela, Mexico and Argentina.
"Here, in the most urbanised continent on the planet, extreme cities have bred extreme conditions – from vast housing estates to sprawling slums," it reads.
"But after decades of social and political failure, a new generation has revitalised architecture and urban design in order to address persistent poverty and inequality."
During the trip the author visited a social housing development in Chile, where residents have been able to customise their homes, and also stopped off in Colombia to see how Medellín – formerly the world's murder capital – has been transformed by innovative public architecture.
The book also features the notorious Torre David office tower in Caracas that has been taken over by squatters, which featured in McGuirk's Golden Lion-winning research project with Urban-Think Tank.
US designer Neil Donnelly created the book's cover, which shows staggered versions of the title in Latin America's main languages: English, Spanish and Portuguese.
"Once the image is removed, the typography below is revealed to have its own unexpected architecture," Verso Art Director Andy Pressman told Dezeen. "Reading the title at that scale feels similar to experiencing a dramatic public space."
Radical Cities also comes a with a short jacket featuring photography by Iwan Baan.
It is available in hardback for £12.59 or as an Ebook for £8.99, and includes 30 photographs over 228 pages.
