Competition: Dezeen has teamed up with conservation group the Twentieth Century Society to offer five readers the chance to win a guide to London's Brutalist architecture.

Congratulations to the winners! Jeremy Marshall from the UK, Tomek Wróbel from Poland and Sanyung Lee from Finland are among the winners who have been contacted about their prize.

The double-sided foldout map features over 50 leading examples of Brutalist architecture, including the National Theatre, the Barbican and Balfron Tower.

Lesser known buildings like the Elephant and Rhinocerous Pavilion at London Zoo, Hyde Park Barracks and Keeling House in Bethnal Green are also amongst the points of interest, along with details for each building including the location, date, the architect and listing status.

"This map is a fantastic opportunity to highlight some of London's boldest and exciting post war buildings," said Henrietta Billings of the Twentieth Century Society. "Ten years ago this style of architecture was completely out of fashion, but now more and more people can see what's great about these buildings."

Alison and Peter Smithson are believed to have been the first architects to adopt the term Brutalism – deriving from the French term for raw concrete béton brut used by Le Corbusier in the late 1940s.

Over the years, the movement has provoked strong reactions and arguments. Recently, a bid to grant listing status to the Brutalist Robin Hood Gardens estate in east London failed and the local MP called for it to be "brought down ASAP".

"Brutalism challenged traditional notions of what a building should look like by showing its construction and not disguising materials," said the organisation. "Most were built from concrete which was functional and affordable – important factors as Britain was rebuilt after 1945."

"The Brutalist London Map is designed to affirm the value of these buildings and to inspire further consideration of the Brutalist architecture today," it added.

Brutalist London Map is the result of a collaboration between the Twentieth Century Society and independent map publisher Blue Crow Media. The pair are due to release an Art Deco London Map in March 2016.

The map will be available to purchase from the Blue Crow website, Foyles, the RIBA shop and Stanfords for £8.
