Australian architectural firm Cox Rayner Architects has created the Left-Over-Space House. Completed in 2012, this contemporary home in Paddington, Australia, shows how a small narrow lot can be used effectively to create a comfortable living space. In the three metre wide frontage to the old cottage is a new study designed through its portals and window boxes to engage the street. Where the site slightly opens up behind the cottage to an open, roofed and screened staircase atrium forms the primary social space. A small bridge is a library connecting it to kitchen and living room, and beyond to stacked bedrooms and a stair to a roof deck.
Privacy from close placed neighbours is gained by a series of iron screens whose perforations for light are the patterns of peeling paint of weatherboards on one of the neighbouring cottages. The screens slide or swing out to engage the neighbours when desired and to mediate different solar positions. They are one of an array of details rethinking the typology of the private house, no matter how small, as both sanctuary and communal participant. The project recycles an existing small cottage as a piece of the house to which extensions in front and back are grafted in 3 metre and 5 metre wide portions respectively. The forward portion is a single level study room for architectural practice, or if later to be used by a new owner, a potential small office. The former cottage is opened up to form a conduit to the rear portion, it also comprising the dining space. As the site falls steeply to the rear, two levels of bedrooms are attached to the old cottage piece, with a staircase atrium running longitudinally beside a library which also bridges the front and rear parts of the house.
