Daniel Maskell

Chair of Board of Trustees

Daniel is is a Research Associate at the Univeristy of Bath working on the ECO-SEE project. His passion for earth construction is mainly within the new build sector; which is fostered by his PhD work. It is his belief that mainstream adoption of earthen construction can utilise the environmental benefits on a wider scale and have a significant and measurable impact. This approach has become the rationale for his current research and will become key to his planned future work in academia.

Robin Britain

Robin is an architectural and building consultant based in the East Midlands, UK.  He developed an interest in cementitious and conglomerate building materials as a building student in further education, pursuing this during higher education with architectural degrees at, undergraduate level, and that being related to environmental, ecological and heritage building with research at post-graduate level; in particular the use of plant fibres and specifically industrial hemp with various lime binders.  He has continued to develop through research, the use of such plant fibres with low-impact binders focusing on the use with earthen resources as well as alongside other natural materials.  He has additional interests in the vernacular use of such natural resources with construction and architecture and various impacts, including toxicity and healthy, well-being with buildings.  He was formerly a volunteer director for former non-profit organisation, the Heritage Skills HUB for the Midlands, promoting and supporting heritage building, crafts and skills.

Sally Mareike

Sally’s interest in earth building stems from her undergraduate studies, her career as a potter, and an MSc from the Centre for Alternative Technology (CAT), Machynlleth, Wales. Her thesis experimented with creating a low-impact, insulating, healthy, breathable clay plaster, containing clay, hemp and cow dung.

In 2014 Sally set up and has since worked with Building Naturally Ltd to promote the use of natural materials in construction.

Working with EBUKI, Sally’s intentions are to help increase the knowledge and provision of healthier buildings, to re-skill society for a future without fossil fuel and to reduce CO2 emissions through low-impact construction techniques. Earth can do it all!
