Global warming has a detrimental impact on extreme weather events including flash floods. In the past, Sheffield has suffered devastating floods leaving thousands of people without power and even without a home. This devastation will only get more frequent and severe as global warming increases.
The current design of the interchange will result in it being an unusable space during flooding leaving the roads unusable. Therefore, this design concept will allow the interchange to serve and house the community during extreme flooding events. This will work as the interchange will double up as an evacuee centre once the interchange site has warnings for flooding. This shelter will be for people whose homes have become unhabitable due to flooding.
To create a space which is habitable when flooding, the interchange will use an amphibious design where the architecture is mainly rested on solid foundations, however, in the event of a flood, the entire building will float. The amphibious architecture uses a concrete basement in a concrete hole that will collect water and create buoyancy due to the density of the basement.
To avoid damages caused by these extreme weather events, the interchange will compact telescopically into the main building before the flooding. The furnishings will adapt depending on the required usage of the space. The colour scheme in the interchange and the evacuee shelter will have colours and materials that are associated with luxury to provide the users with a sense of calm and comfort during this stressful time.
