Two more example works from Heatherwick Studios have given me ideas using topography in my work.
This first work is very sweeping and could be a good way to start/ end the bridge as well as use the internal construction to form interesting spaces.
This second one is almost the complete opposite. It is actually designed as the facade of a building but could easily be laid down onto the floor. It is not as practical as the first example but certainly presents possibilities.
