Ambiguous Spaces, the newest installment in the Pamphlet Architecture series and a return to Pamphlet's own progressive roots, features the architectural fictions "The Pregnant Island" and "Nuclear Breeding." These two projects develop alternative urban concepts that address the challenges presented by the specific situations and social dynamicsdescribed in controversial locations such as the Brazilian Tucurui Dam, the Three Gorges Dam in China, and former English nuclear test sites. Using narrative techniques, fictional programs, ambiguous spaces, and building devices, AmbiguousSpaces explores people, communities, and even entire cities oppressed by a lack of freedom.
