This vol­ume is a com­plete mono­graph on the work of Ger­man ar­chi­tect Hans Koll­hoff (b. 1946) and his part­ner, Hel­ga Tim­mer­man (b. 1953), with whom he has col­lab­o­rat­ed since 1984. It pre­sents 100 build­ings and pro­jects com­plet­ed by Koll­hoff and his firm since the 1970s, be­gin­ning with his Pro­ject for an Anal­o­gous City of 1976 and in­clud­ing com­pe­ti­tions, of­fice and mul­tiuse build­ings, banks, apart­ment com­plex­es, and ur­ban plan­ning. Koll­hoff be­gan his teach­ing and in­ves­ti­ga­tions in­to the city dur­ing the post­mod­ern de­bates of the 1970s, when he stud­ied with O.M. Ungers at Cor­nell Uni­ver­si­ty. Since that time he has fo­cused on large-​scale ar­chi­tec­ture and its role in pre­serv­ing the ur­ban land­scape, striv­ing to dis­cov­er the essence in tra­di­tion­al ar­chi­tec­ture, and to build a new tra­di­tion from it. Jasper Ce­pl in­tro­duces this book with an in­ves­tiga­tive es­say ex­am­in­ing Koll­hoff's ca­reer and the­o­ret­i­cal di­rec­tion since the late 1960s. Fol­low­ing the in­tro­duc­tion are 100 pro­jects pre­sent­ed chrono­log­i­cal­ly, in­clud­ing re­cent work in Berlin, such as the Daim­ler­Chrysler High­rise Build­ing (2000), the Ex­ten­sion of the Perg­a­mon Mu­se­um (2000), and the ren­o­va­tion of the For­mer Seat of the Re­ichs­bank for the Min­istry of For­eign Af­fairs (1999).
