We see so many mediocre office building designs that it is easy to forget just how complex and innovative a well-made one can be. Such is the case with the headquarters for the Belgian financial firm CNP (Compagnie Nationale a Portefeuille) in Charleroi, Belgium. Designed by the office of Belgian architect Philippe Samyn, the CNP Headquarters is a masterwork of ecologically oriented construction and refined aesthetics. In this monograph el-Khoury and Pasnik document the rich and dramatic architectural vocabulary of this project.
