Acting as a river-based archive of the Thames and located on the banks of Greenwich, the project is a reinvention of the idea of the museum. Alex’s investigations into climate change, flooding, museology and the historic urban identity of the Thames led him to see it as a dynamic embodiment of the climate crisis. From this analysis, the building seeks to be made ‘of the river’, collecting artefacts to display within and being shaped by its flow. The proposal derives primarily from a strong sense of tectonics that have been directly shaped by a dynamic process of time-based fluidic simulation and iterative digital modelling. The undulating cavernous forms are sculpted by the flows of the river, but are also intended to directly control the water itself. Eddies and currents are controlled to encourage debris to form in and around the building, so as to create and curate the river's artefacts. Water is drawn into the museum to regulate internal environmental conditions and acts as a lifeblood, illuminating the river's artefacts. This is a monument to the Thames, to its mythical power and to the flow of time itself.
