Peter Ahrends, Richard Burton and Paul Koralek have been friends for 50 years, since meeting as students at the Architectural Association in London. Their practice, ABK — established in 1961 on the back of winning the international competition for Trinity College's Berkeley Library — has developed into the longest-lived three-way partnership in British, or Irish, architectural history. Their achievements have been celebrated in London and Dublin with the publication of a new book, Collaborations: the Architecture of ABK. It hasn't been plain sailing for the three amigos, however. Far from it.
