Congratulations to the winners! Rohan Kempadoo, Jessica Nieri, André Almeida, Raimon Pujol Veciana and Tracy Forrest.
The Stirling Prize is awarded by the Royal Institute of British Architects (RIBA) in recognition of the building that has made the greatest contribution to British architecture in the past year.
The RIBA Stirling Prize: 20 book features every shortlisted and winning building from the competition's first 20 years.
It is written by the RIBA's former head of awards Tony Chapman and features an introduction by Sir David Chipperfield, who was awarded the prize in 2007 for his Museum of Modern Literature in Marbach, Germany.
Other projects included in the book are the Media Centre at Lord's Cricket Ground by Future Systems, Zaha Hadid Architects' MAXXI National Museum of Art in Rome, Herzog & de Meuron's Laban Dance Centre in Deptford and the 2015 prize-winning Burntwood School by Allford Hall Monaghan Morris.
Detailed passages explain how each winning building was planned and constructed, and reveal the jury's comments.
Commentaries are also provided for the shortlisted buildings from 2006 to 2015, including Foster + Partners' Gherkin skyscraper, the Gateshead Millennium Bridge by Wilkinson Eyre Architects and the 2012 London Olympic Stadium by Populous.
Five winners will receive one copy of The RIBA Stirling Prize: 20. The book, which is published by Merrell Publishers in association with the RIBA, will be released on 6 October 2016 and retail at £40.
There are six projects vying for the Stirling Prize 2016, which will be announced on Thursday, 6 October 2016. Among the shortlist is Damien Hirst's London gallery, an Oxford university building by Herzog & de Meuron and a forest home for a pair of artists.
