This edition, the fourth in a series of monographs that chart the architectural and speculative output of the Danish office CEBRA, sees the firm expand internationally to Toronto, Monterrey, Abu Dhabi, and elsewhere across the globe. Through a chronological presentation of projects from 2013 2020, a pattern emerges: in both large and small projects, bold expressions, CEBRA s signature crystalline geometry and what founding partner Mikkel Frost calls architectural fractals are tempered through a sense of approachability, tactility, and co-authorship. With an interview by designboom s Philip Stevens and 35 new projects, CEBRA files 04 marks the 20th anniversary of one of Denmark s most iconic design firms.
