Concrete Oslo gives the reader an opportunity to explore a great number of buildings, structures and objects through curated tours across the city. But more than mere tourist guide, this book is an opportunity to reflect upon an enigmatic building tradition and to engage with the city, in literal and physical ways. Accompanying the tours are a number of theoretical essays, original drawings, unique photos and other historic documentation combining historical accounts and theory with 1:1 field studies. The book springs from a master studio course, taught by the three editors of this volume, at The Oslo School of Architecture and Design. The format escapes the confines of academia and invites everyone to indulge in an architectural treasure hunt in Oslo.
