Hernan Diaz Alonso is one of the most influential and innovative architects working today. Director of one of the leading architecture schools in the USA, his visionary schemes span all scales, from silverware to master plans. Founded by Alonso in 2001, Xefirotarch's multidisciplinary design obsessions are based in an appreciation for mutant forms, which have been realized in designs for architecture, sculpture, products and design objects. This showcase of works presents the practice's major designs since 2001, including plans for Helsinki Library, Budapest Museum and major architecture projects in Barcelona.
