Nobbs Radford Architects designed the 'Birchgrove House,' a renovated cottage located in the suburb of the same name, in Sydney, Australia.
The original structure was a weatherboard cottage, and the architects updated the design to maximize its relationship with the outdoors. They replaced the external walls of the upper level with a facade, that can open and close; when closed, it mimics the original weatherboards. The architects also extended the main bathroom out towards the upstairs balcony, allowing for a unique outdoor experience.
Finally, the architects replaced the existing staircase with an protracted stair spine. Joinery wraps fill the pockets above and below the stair with storage space, ensuring a completely new spatial experience. A concrete stucco wall runs the length of the staircase, diffusing light and shadows that enter from the glazed roof above.
