This alteration to a late 1990s spec house replaced a jumbled series of tiled hipped roof forms with three simple gables. The house’s original organisation was largely retained but internal spaces have been transformed by the volume generated inside the stepping gables. Inside, new volumes afforded by the gable roof forms have replaced what was previously a standard 2.4 metre ceiling throughout. The entrance hall now rises the full two-storeys through the centre of the house and a third upstairs living area has been created by utilising what was previously an enclosed ceiling space.

The height of the new gable roof is also expressed within an upstairs bathroom which has been retained in its original location but enlarged by making use of previously dead space within the original hipped roof form. A limited palette of exterior materials is used – cream bricks and pale grey roofs for single storey elements and dark corrugated Colorsteel for the roof and wall cladding of the central two-storey form. Exterior brick cladding continues into the kitchen and entrance spaces. Light and airy volumes and more compressed spaces introduce spatial clarity and coherence.
