In this luxury sustainable home, the requirements of modern living have been provided while ensuring that neither the amenity of neighbours, nor the heritage quality of the street is compromised. The once dark and haphazard house now benefits from good natural lighting, good connection to outside spaces, intelligent connection between spaces and excellent use of the compact site through placement of the built form and design detail.
In essence, the courtyard house extension is made up of three elegant architectural elements. A timber link element contains the kitchen and connects to the masonry living room ‘pod’. Above this sits the sculptural second floor bedroom ‘pod’. The overhang of the second storey ‘pod’ functions as sun-shading to the northern ground floor windows and creates an undercroft to the south-west terrace.
The extension does not attempt to emulate the existing heritage home. Rather, the design complements and highlights the distinctive character of the existing home and increases the number of inhabitants who can comfortably, and sustainably, live there. Important environmental features including:- passive solar design, energy efficiency, water storage and the use of sustainable materials. Taking its cues from the existing timber building (and the timber buildings in the vicinity) , the extension features shiplap timber cladding to the linking element and radial-cut weatherboards to the second-storey bedroom ‘pod’.

The conventional response to linking old and new is often to join them via a glass corridor, by making our link functional we reduced the amount of useless corridor in the project.
