As the Tidal North Sea flows into and withdraws from the River Thames, an estuary condition occurs just East of the city of London, affecting its ecology with its dynamic exchange of currents. In one typical day, the elevation of the River Thames fluctuates from 10 feet above the river bed to 30 feet, and back down again. Our project proposes an urbanism consisting primarily of a concentration of rafts floating along the River Thames, whose motions are activated by the ebbs and flows of the River to create new configurations and programmatic adjacencies. The entry to our proposal transitions from natural terrain to a permanent canopy system on the North and South banks, providing covered space and renewable energy to regular markets and pop-up events so common to London. As one progresses through the site, they are drawn along a pivoting arm, guiding them down to the drifting rafts, as they experience London from the river’s perspective. The rafts themselves host performances, park spaces, and exhibitions, as their kinetic roof systems open and close at the occupant’s discretion. Finally, the rafts lead to the Shifting Bridge, whose precision in fabrication and technology allows it to sway in response to the River, further extending the estuary condition through its animated structure.
