There are many positive implications for the use of seaweed in the construction of prefab panels. According to Kathryn Larsen — who is inherently interested in the instrumentality of the material, eelgrass is "naturally fireproof, rot-resistant, carbon negative, and becomes entirely waterproof after about a year." These characteristics become incredibly alluring as the architecture industry is shifting focus to be more efficient, cost-effective and sustainable.
The blooming potential behind the use of seaweed as prefab panels came to Kathryn Larsen as she was learning about how the Viking thatched their roof in seaweed. After heavy research and prototyping, the designer was able to develop "a set of prefabricated eelgrass-thatched panels to suit roofs or facades."
