Oysters: A Building Block for Coastal Conservation

Oysters: A Building Block for Coastal Conservation


Eastney Beach, Eastney, Portsmouth, South East England, England, United Kingdom

Project Description

Questioning the efficiency of current sea defence strategies and it's impact on biodiversity.

This projects aims to address climate resilience of inter-tidal ecosystems as well has the health and well-being of Portsmouth's younger generation.

To raise awareness of the importance of coastal biodiversity to the resilience of our coastal infrastructure and seas.
To promote the health benefits of children playing outdoors. As electronic devices are becoming ever-more present in our lives, children today are spending much less time outside than their parents did growing up. This proposal seeks to create an experience where wildlife habitats are incorporated within the architecture to increase interactivity and interest with the outdoors.

This proposal was achieved through researching methods of sustainable coastal defence strategies and uses of natural by-products to use as a building material. Through iterative physical modelling a design of a 3D printed, biopolymer, panelling module was developed using oyster shells, that would give the façade a depth to accommodate for wildlife to inhabit.

This project displays a resourceful use of natural waste to create a renewable and biodegradable building material. Whilst this is largely untested using oyster shells, exoskeletons of lobsters and crabs have been used to create 3D printable materials.
