Constructed on a 10m wide site these two homes explore an old type of housing familiar to Subiaco. The semi detached house is stretched over three pavilions to create a sequence of courtyards that allow north facing sun to passively heat spaces in winter and south westerly winds to cool spaces in summer. The traditional appearance to the street is corrupted by a more challenging selection of material, rusting steel and glowing opal polycarbonate provide a counterpoint to the historic surrounding houses. Sections are shaped by designing for sun penetration resulting in parabolic forms, a gable to the street and a skillion to the rear. Material and construction systems were selected based on economy, minimising construction time (and neighbour disturbance) and consistency with the exterior.
