The house that straw built
home a masterpiece of ecological planning
Surrounded by saplings, wildflowers and running streams, it's easy to focus on respecting and preserving nature. When planning and building his home in Grey County, Richard Griffith took a particularly adventuresome route.
"It was time to act on my words and my beliefs," he says. "It was time to make a life-changing decision."
He opted to forego commonplace building conventions and materials, even a standard heating/cooling system. Instead his home is built using straw bales, which are noted for their enormous insulation properties — although, since even the hardiest of conservationists need warmth in the Canadian winter, the house has a large fireplace.
Today, tucked up in the picnic areas and cross-country ski trails of the Blue Mountains, Griffith enjoys the benefits of his choices. He's warm in winter, just fine in summer, too, and no heating bills trouble him as he watches for deer, wild turkeys and other wildlife.
This is his dream house.
Studies in Restoration Ecology at Niagara College in St. Catherines, following a stint at the University of Toronto studying English, led him to the conclusion that environmental problems were the result of human attempts to dominate and control nature in ways that were unnatural. Griffith became a permaculturalist, an advocate of an attitude toward design of housing communities and gardens based on the principles of nature.
"Permaculture is a design system based on patterns in nature. Nature wastes nothing and everything goes in cycles — that's a vital pattern that we have generally forgotten," he says.
An inheritance allowed him the opportunity to put his money where his mouth was.
"I could have gone either way," he recalls. "Get a nice job and a nice place or build this house. It was time for a life decision. I had been skiing up here for years and a friend told me about this land. Within a week, I owned the property and began to plan."

After a year, Griffith came up with a careful site plan for his 3.6-hectare property that orients the house to the south for the natural light and heeds the lay of the land and nearby trees. He hired Toronto-based architect Monica Kuhn and structural engineer Gerry Mason. Greg Allen and Mario Kani of Sustainable Edge Designs planned the mechanical systems.
And yes, there were those straw bales.
"I had seen a slide show of a straw-bale house," he recalls. "It was a beautiful-looking house. Of course, the beauty of the straw is its insulating properties.
"This house has been my opportunity to put my environmental beliefs into action."
One of those three pigs had it right the first time

Did the first of the three little pigs have a good idea after all? The insulation value of straw lies in the fact that it is hollow and the air is doing the work. Bales are 35 centimetres thick.
"If you have land in somewhere like Wyoming and you have a million or so bales of straw lying around, the idea of using it to build a house is appealing," says Gerry Mason, a structural engineer. "That's the type of application that inspired the first straw bale houses."
"Using straw bales is a viable construction technique," architect Monica Kuhn stresses. "We used a post and beam construction (to build Richard Griffith's house), but there are ways to make the straw load bearing. It has to be stored in a dry place, covered for a year."
Once that's out of the way, the golden blocks are surprisingly easy to work with and stack.
What about mice or bugs? "Straw is just cellulose. There is really no nutritive value," Griffith says. "The straw in this house will outlive me."
Griffith's house has cost him nothing to heat, as he has been able to cut down and supply his own wood for the masonry heater/fireplace, which consumes about five bush cords per heating season.
Finding insurance was an issue, however. "When I was looking there was an attitude of `what are you doing? Living in a haystack?'" Griffith recalls. He ended up getting insurance from the Co-operators in Collingwood at a cost of about $1,400 a year.
It's unlikely that straw-bale housing will become a trend in cities, where there is precious little room for 35-cm-deep walls. However, there are other such homes in Ontario and a Straw Bale Building Coalition, which holds a yearly open house tour across the province.
"I definitely think the concept is gaining popularity," Griffith says. "My firm may be building one this summer in Prince Edward County," adds Kuhn.
