In our Master thesis project 'Plastic Island' completed at Chalmers school of architecture we investigated the possibility of creating 3 small structures out of ocean plastic. The 3 small houses contain the a program of a public diving center on Nordkoster, a small island off the coast of Strömstad, Sweden. Here we collected marine waste from the proposed site, transformed it and put it back where it was first collected. This design proposal raised awareness about marine plastic while also showcasing the potential in turning this waste into something valuable.
