First Ontario concrete houses being built

The first all-concrete house in Ontario is being built in Woodstock and a second is scheduled to start this summer in Burks Falls.
Tilt-Wall Ontario co-founder Len Overbeek said the technology is old but the future looks promising.
“Even though it’s been around for 100 years in the United States and other parts of the world, it’s very new to Ontario,” Overbeek told the London Free Press.
The cost of a tilt-up home is around 10 per cent to 15 per cent more expensive than a traditional build, Overbeek said, but he thinks this type of home may become popular with specific clients.
“It’s a custom home building type,” he said. “It wouldn’t be something you would use in a subdivision. Multi-family dwellings is another area that we would like to explore.”.”
Tilt Wall is not a homebuilder, but has been involved in concrete commercial construction for 15 years. Overbeek, who had the Woodstock house built as his own residence, said that his company just builds the walls for custom residential projects.
“Somebody interested in building a tilt-up home would have to come to us and we would have to work together,” he said. “We would find a builder for them.”
A strong builder is recommended: The 4,100-square-foot Woodstock house required 39 pre-formed insulated concrete panels, the largest of which was 38 feet high and weighed 39 tons.
As well as super durable, concrete houses are energy efficient, Overbeek said. He explained that a concrete house has no thermal bridging between the exterior and the interior. “If you took a normal stud framed home you have lots of solid wood for thermal energy to travel through. You do not have that with a tilt-up building, there is solid 100 per cent continuous insulation around the entire perimeter of the building.”
