Annual Natural Homes Tour

The annual natural homes tour took place on Sunday Sept 29th - with 29 homes across Ontario participating. It was a fantastic opportunity to view a wide range of natural homes that featured straw bale, rammed earth, hempcrete and many more natural building methods, as well as alternative energy and heating systems and much more! The annual tour typically takes place the last Sunday of September - keep an eye on this site for a date for next year. 

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

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


Visit our Natural Building Gallery to see houses built out of straw, wood & earth!

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!
