Architects Nannette Jackowski and Ricardo de Ostos have developed a unique form of experimental architecture that reinvigorates its strength as an agent of political and societal change. 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 dynamics described in controversial locations such as the Brazilian Tucurui dam, the Three Gorges dam in China, and former English nuclear test sites.
