Petersham, Sydney, 2016
An articulated two-storey volume is sensitively stitched to the rear fabric of a Federation masonry and hipped envelope. Environmental, cost and planning values entailed in retaining the original fabric are augmented by a modestly sized footprint and lightweight-framed envelope in a crafted "new build" enabled at the rear. It has a sectional split-level relationship to the original house that harnesses the fall of the site to the rear, allowing the cellular front plan to vertically and horizontally unfurl into a series of connected interior spaces that expand to its setting.
Fenestration placement harnesses natural light and promotes passive ventilation, while acoustic attenuation measures for alternative air ventilation, insulation and internal linings assist the performance of the envelope in ameliorating latent aircraft noise. Surrendered floor area enables generously carved voids flanking an upper bridge for diverse views to sky, trees, and outdoor spaces, while encouraging a spatial interplay of public, semi-private and private rooms.
