Announcing our 2021 Virtual Natural Homes Tour 

This year due to the continuing concerns around the Covid -19 virus, we will be replacing our in-person Natural Homes Tour with some natural home video clips from some of our members and friends. Please watch our Facebook page and this website for more information as it becomes available. We hope to return with an in-person tour in 2022!


A huge thanks to all the homeowners who voluntarily opened their homes to tour-goers and to all the people who took part in our last tour in September of 2019. 


See a CTV news video clip of one of the homes on our 2019 tour.

A Natural Home Tours Thank You


Over the years, many homes and buildings have participated in our Natural Building Annual tour.


Many of the homes that have been featured were models of innovation and energy efficiency and featured living roofs, natural clay wall finishes, rainwater catchment systems, grey water systems, composting toilets, while others incorporated solar and wind electrical systems, high efficiency wood burning appliances, solar domestic hot water systems, as well as a variety of other interesting green technologies.


The Ontario Natural Building Coalition would like to thank all the volunteer homeowners who have over the years graciously opened their doors and welcomed tour-goers. The annual tour would not be possible without them!
