Mr. Wickens, who specializes in residential architecture, faced a couple of significant challenges in the Swansea build. One was the location next to the pond, which means that the Toronto and Region Conservation Authority had to approve the project, along with City of Toronto’s department of Urban Forestry. Acquiring permits was a lengthy process. To ensure that the house would never shift or sag, they built it on the type of helical piers that more typically support a commercial building or condominium tower. ‘There’s a fortress underneath the building,’ Mr. Wickens said. ‘It’s kind of an indestructible thing.’Craig Williams
