Competition: Dezeen has teamed up with Danish architecture studio 3XN to give away three copies of the firm's new monograph.

Congratulations to the winners! Jeff Jang from Canada, Alexandru Patrichi from Belgium and Joseph Brady all won a 3XN monograph.

The giant hardback book is dedicated to the work completed by 3XN during its 27-year history so far.

It features the firm's most recognisable work, such as the Blue Planet whirlpool-shaped aquarium and the regional headquarters for the United Nations in Copenhagen, plus the Museum of Liverpool.

A total of 32 projects are documented through photos by Adam Mørk, critical essays, case studies and interviews.

The monograph includes an introduction by architecture critic Christian Bundegaard, along with interviews with 3XN founder and creative director Kim Herforth Nielsen and head of competition department Jan Ammundsen.

Architect and writer Terri Peters comments in her introduction: "At 3XN, architecture is everywhere, it is always the starting point and the answer to complex client briefs. The studio is concerned with all of the things around a building, how people use spaces, movement through the building and views inwards and outwards. It becomes clear in visiting a 3XN project that the office takes care to design buildings for people, for users, for passersby, for visitors, for locals and for future generations."

Visit the Idea Books website to see where the monograph, published by Archilife, is available in your country.
