The ONBC is a member based advocacy group of designers, builders & homeowners working to promote healthy, high performance natural building strategies in the construction industry.

The Ontario Natural Building Coalition was founded  in 2003  under the name, Ontario Straw Bale Building Coalition.  In 2013, the organization decided to change its name to the ONBC to reflect the growth of natural building in Ontario and to capture the wider scope of materials that were being used by our members.  


We believe that all housing should be healthy, sustainable, inspiring and resilient.

We promote the use of natural, non-toxic materials that can dramatically reduce our carbon footprint while achieving high levels of energy efficiency.

We support our community of building professionals and homeowners in the positive transformation of our built environment.

We foster the exchange of ideas, innovation, resources, and social opportunities across Ontario.

Meet the Board of Directors


Interim President / Treasurer

Adam lives in Perth, Ontario, and works with Julian Smith and Associates Architects. Exposed to the practice of architecture from early childhood, he has been involved for years with the uses and patterns of traditional materials in existing and heritage buildings. Often ‘natural’ by default, certain traditional materials can still have significant carbon sequestering properties. There is also a mounting body of evidence underscoring the significance of using natural materials to achieve occupant wellbeing, be it through emotional support or indoor air quality. Combining these various cultural and technical factors, Adam draws significant connections between the use of traditional materials and practices, on the one hand, and a variety of contemporary needs, on the other. Based on experience working in a tropical context, Adam’s architectural work goes further in attempting to integrate the natural world by blurring, where possible, the distinctions between building and landscape.

Principal, Dwellings Custom Homes

Dwellings is a company that builds houses using craft, integrity, good tools and our wits. Over the past six years we have had the opportunity to work on an amazing variety of projects that have served to deepen our carpentry and timber framing experience and also explore the world of natural building. The synthesis of craft, sustainability, durability, good design and the use of modern systems are what we bring together to create a house that is efficient and timeless.

We are heritage trained carpenters (by way of the Heritage Carpentry program at Algonquin College) and bring a love of architecture, sensible design, quality materials and good workmanship to every project. We work out of the Perth, Ontario area and try to stay close to home for larger scale projects such as whole houses. In a given year, we will generally work on two large scale projects (houses or additions) and a wide range of smaller scale jobs, such as timber frame entryways, pergolas, sheds, outbuildings, staircases etc.
