Natural Building and Ecological Design Colloquium 2019

...where you will meet "cob fathers" and "cob mothers" and gather with other folks who love natural building!

Friday, June 14 - Sunday, June 16

Join us in celebrating OUR 20th year at OUR ECOVILLAGE! We are inviting the natural building community and friends to a fully immersive weekend of learning, gathering, honouring, sharing and celebrating!

The Natural Building Colloquium is a gathering for natural building enthusiasts: builders, teachers, professionals, and those who are passionate about natural building. It is a place to exchange the latest developments in practical applications and technology and share ideas with other people in the field. We will look at where the natural building movement stands in regards to professional support, permits, and finding qualified builders.

OUR “Lawful Permaculture” Demonstration Site & Education Centre is an immersion of a wide range of natural buildings that are cob, straw bale, rammed earth, earthship/tire, living roofs, or rubble trench foundations and are all permitted and engineered. Whether you are a green builder, regulatory official, designer, or home owner/builder, this (un)conference will open the doors for whole new ways of understanding ecological design and building.

This is NOT a workshop. We will gather for panels, presentations and network with one another with social time. We also plan on sharing our own stories as well as honouring the elders in the natural building movement.

OUR Ecovillage is a demonstration site for permaculture and sustainable living. OUR buildings show a variety of natural building methods and designs. We have worked with regulatory processes and professionals to receive permits for all of our buildings and to blaze the path of legal natural building for others. One example is OUR re-zoning project, which has allowed other groups to follow our demonstration project with similar ambitions.

We offer accommodation in some of OUR natural buildings: the Healing Sanctuary, shared dormitory and other beautiful cob spaces.

During the colloquium we will offer glimpses into many of the natural buildings on site during a guided tour led by natural building expert Elke Cole. Elke had been involved in the design, build, and execution of OUR natural building projects from the start.
