Parnall Bio Engineering is a new technology driven project dedicated to improving health and quality of life through engineering. 

We are developing a structural bio-composite system called Hemposite™ which aims to offer an innovative solution to the future of construction. 

Our aim is to develop a novel building superstructure concept which substitutes conventional steel and synthetic materials for a superior low carbon bio-composite material befitting of current technology and environmental obligations. Using an assembly of readily available components, our system would create a building envelope that offers phenomenal performance. 



Our aim is to develop a building method that both minimises waste and energy demand, whilst sequestering carbon within its material structure as well as being quicker and easier to construct. 

The fully integrated renewable energy technology offered by Hemposite™ allows the building to be self-powering through solar impregnation and exist anywhere in the world without reliance on state infrastructure. 

Our plan is to build a demonstration structure using Hemposite™ with a unique look and feel, lending a brutalist monococque design with a more organic feel through natural materials and colour.

Eleanor SteeLE, Creative Support

After completing her Degree in Interior Design with Falmouth University, Eleanor joined Parnall to work part time on the Panther Project build. Since she has expressed her interest into the PBE project with its aspects of green design after living in Sweden and gaining an understanding to the importance of sustainable buildings and lifestyle.

Eleanor has since began working on the project part time providing her creative support to aspects of the project, with fresh ideas and visions to further develop the look and feel of the building.
