Congratulations to the winners! Hayley Wong from the USA, Weronika Lewicka from Poland, Jacques Rigolet from Switzerland, Lorenzo Dalla Benetta from Italy and Paolo Augello from Italy all won a PK Arkitektar monograph.
Pálmar Kristmundsson Arkitekt follows the career of Pálmar Kristmundsson, who set up the Iceland-based architecture and design studio PK Arkitektar in 1986.
The book begins with Kristmundsson's makeshift fishing structures and ends with recent projects by PK Arkitektar.
Projects include a holiday home near Reykjavik that offers panoramic views of the dramatic Icelandic landscape and a minimal white house in a suburb of the Icelandic capital with a wall clad in slabs of red volcanic stone.
Published by Arvinius + Orfeus, the 240-page book includes a text by the architect himself along with sections by Daniel Golling, Julie Cirelli and Gert Wingårdh.
The writing is accompanied by images including photographs, drawings, plans and sections.
