The Cosgrove House offers a quiet, light-filled home on a compact and busy site, through a well-considered addition to a 1920s heritage-listed building in the heart of Woollahra in Sydney. Tzannes’ thoughtful design for the new residence brings contemporary comfort to a historically sensitive location, combining privacy and amenity.
The new three-storey addition comprises a two-bedroom home with large living, dining, kitchen and terrace spaces above a garage and entry. The layout has been carefully planned to shield interiors from street noise and maximise natural light and privacy. A central stair along the eastern edge helps buffer sound, while living areas face west to capture sun and leafy views.
Materials were selected for both performance and longevity. Robust concrete defines the lower floors, while a lightweight copper-clad roof forms the top level. Screens and planting maintain privacy from neighbours, while also softening the home’s connection with the street.
