Ken Soble Tower
Built in 1967, the Ken Soble Tower is the oldest high-rise multifamily building in the portfolio of City Housing Hamilton, the housing corporation run by the city of Hamilton in Ontario. Having been in decline for several years, the 18-story building is now on track to be the first residential high-rise EnerPHit in North America. With more than 730,000 units in many thousand similarly constructed concrete towers in Canada alone, this retrofit serves as a groundbreaking model for how to rehabilitate this aging—and yet still vitally important—housing stock.
Before choosing to retrofit Ken Soble, CityHousing Hamilton had examined various options for dealing with the property, including sale, rebuild, and capital repair. It was determined that making significant improvements would cost substantially less than demolition and a new build. In addition, extending the life of the concrete structure, and its associated embodied energy, greatly reduces the overall carbon footprint of the project.
