unfurled house designed by christopher polly architect for sydney family
a 100m2 addition designed by christopher polly architect attaches to a federation style dwelling in petersham, sydney, australia. deemed the ‘unfurled house’, a lightweight volume expands outwards from a formal front, providing a split-level space that strengthens visual and physical connections to the natural environment.

the two-level structure by polly was developed to respond to the immediate setting as well as established conditions of the existing home. a linking space blends original and contemporary, acting as nexus for utilities, interior circulation, and a small courtyard within.

in rear, angled extrusions stretch into the backyard. in addition to mediating space in regards to scale of adjacent homes, the features provide cover for terrace storage. the uppermost ‘wedge’, hosts a private reading space and master bedroom, with a large void that overlooks public living space below. views look to the sky, trees, and outdoor spaces, and architectural detailing creates an interplay of public, private, and spatial concerns.
