Since the sunniest part of the lot is at its center, Balaban designed the residence around a courtyard. "The outdoor space became the heart of the house," Balaban says. "You have the usual array of mechanical 'bells and whistles'—low-consumption fixtures, heat exchanger on the ventilation, radiant concrete floors, etc.— but the courtyard is the main green feature. It brings natural light to the basement and the center of the structure. It also creates a microclimate, protected from the wind. In combination with the stacked stair, it helps provide passive natural ventilation using a chimney effect through the house. The stepped courtyard also gives every space in the house direct access to a patio."  Photo 3 of 9 in A Minimal, Metal-Clad Montreal House With A Hidden Courtyard by Diana Budds
