This project is the extension and reworking of an early Twentieth Century Arts and Crafts bungalow. In designing the new extension it was important to maintain the integrity of the original house and it’s positive contribution to the streetscape. Conceptually the old and new are not physically or visually distinct but simply butt up to each other, with the new rear wing incorporating the materials of the original house but with contemporary form and detailing. The lower level, while extensively glazed on 2 sides, adopts the rough cast rendered brick walls of the original along the western facade, while utilising a lightweight framed upper level clad in white painted cedar shingles, that were used to clad the large gables of the original roof. The restoration of the original bungalow formed a significant part of the building work, as did the maintenance and upgrading of the original landscaping of the house.


The retention of the original section of the house was fundamental to the sustainability of the project. Passive design strategies include a highly insulated building envelope, extensive glazing providing high levels of natural lighting, solar shading by louvres and overhanging awnings, while operable windows and doors provide for cross ventilation.

Innovative sustainable design elements:

The house incorporates the following sustainable design elements: rainwater harvesting tank for topping up the pool and garden irrigation, insulated pool cover, solar hot water system, mechanical and fixed louvres for sun shading, LED lighting, AAA rated taps, dual flush toilet cisterns, ducted underfloor heating and high performance glazing.

Environmental footprint of the building is minimised by:

The design of this house minimises it’s environmental footprint by the retention of a significant portion of the original house while utilising passive design principals for the extension. The incorporation of numerous sustainable design elements and the enhancement of the existing landscaping provide for a low energy, long life building.
