51N4E is a Brussels-based architectural practice led by Johan Anrys, Freek Persyn and Peter Swinnen. Founded in 1998, it has drawn increasing attention and renown through projects for the C-mine cultural centre in Genk, the Groeningemuseum and the TID Tower and Skanderbeg Square both in Tirana, Albania. This book, accompanying an exhibition on the practice at the Architectural Association, features these and 17 other projects alongside essays by Lars Lerup, Dominique Boudet and Stefan Devoldere.
