404:NOT FOUND is distinguished by its resistance to authorial architecture and in its acceptance of the logic of the crowd. The project looks at architecture as an assemblage of crowd-sourced processes rather than the singular vision of a top-down designer. Architecture becomes an act of empowerment and an experiment for the participant, creating a platform and ethos of collaboration that legitimizes and enacts the desires of the user. The user-defined building block is the generator of the architecture. In an app-based process of form-assign-upload-share, the block is propagated, manipulated, and multiplied, creating a rich aggregation of heterogeneous textures, materials, and spaces. 404:NOT FOUND favors the glitch, the mismatch, and the transgression, creating a new typology of museum that rejects the authority of the white box in favor of the participatory.
