The Ontario Natural Building Coalition's 

Annual Ontario Natural Homes Tour

Sunday September 30, 2018 - 10am-4pm.

Natural building construction uses locally obtained and renewable materials, to produce homes and buildings that are visually unique and healthy to live in, while striving to keep energy consumption 

and its’ associated emissions as low as possible. 

As a way of promoting natural building, the Ontario Natural Building Coalition coordinates an 

annual Natural Homes Tour, in the early autumn each year. For the tour, dozens of natural homes and buildings across Ontario open their doors for participants to see examples of straw bale, rammed earth, cob, timber frame, off grid, passive solar, and many other natural building methods and alternative technologies. 

See map below for the locations on this year's tour - 30 locations!

Check back often, as locations are added almost daily!

Purchase your $10 entry ticket here. 

Your ticket entitles you to view as many homes as you would like on the day of the tour. (Sun. Sept 30, 2018)

For groups of 5 or more adults, contact us for group rates.

Under 16 years, no charge.

The 2018 Ontario Natural Building Coalition's annual

Natural Building Conference & AGM 2018

took place on April 7 and 8, 2018, at Camp Kawartha, near Lakefield.

This year's theme was: "Building Within Reach"

This year we continued to include community growth and personal health in our annual natural building conference. We held two parallel streams throughout the weekend: A technical stream focused on our professional member’s strengths and interests - on natural building with an emphasis on pre-fabrication and modular design using natural materials, as well as on-going carbon accounting and regulatory discussions. The community stream focused on personal and community health, reconciliation between First Nations and settler communities and affordable/accessible sustainable housing.

A big thank you to our 2018 conference sponsors!

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!
