Bickford Park House is a full renovation of an old Toronto Victorian brick house that required a major retrofit. The new design consolidates separate apartment units into one family home, and a rear addition is removed to give the family 50% more backyard space. Insulation for the retrofit is added onto the exterior of the building using EIFS (exterior insulating finishing system) - a lightweight wall cladding with integrated insulation - in order to maximise interior space while creating a highly efficient, air-tight home.
