Coastone is a new biomaterial, designed to show the possibility of naturally derived materials. It utilises materials that are found in close proximity, which reduces the carbon footprint due to lower transport. Coastone can be recast easily, with its aim is to shift a user’s perspective on valuing a material, rather than its form. Its current form is a home speculative home décor piece that allows the user to be inspired and see the versatility of the material. It’s aim is to show designers need to have a deeper understanding of their materials to allow them to apply them more effectively in their work.
