This house is located in a leafy suburb in Sydney’s
northwest, a typical lot with a single-story pre-war
bungalow which had a low quality addition done to
the rear at some point in its life. The aim of the
project has been to rejuvenate the original house
and roughly double its floor area with an environmentally
appropriate addition which takes advantage of the
site’s character and results in a light filled living
space overlooking the garden.
Materials and methods of construction have been
chosen for their environmental qualities and appropriateness
to climatic context:
- North facing windows allow the penetration of
sunlight during the winter months to enhance passive
heating.
- Lightweight roof and walls ensure heat-gain
is minimized during summer months. Good insulation
values (R3.0 at roof, R1.5 at walls) minimize
heat-loss during winter months.
- High ceilings, operable windows and ceiling
fans assist in passive cooling and cross ventilation.
- Steel structure minimizes overall material use,
transport and processing, and has a high recycled
content.
- Timber doors and windows ensure a warm feeling
to the addition as well as having good thermal
performance.
ESD strategies incorporated: rainwater tank, skylights,
cross-ventilation, ceiling fans, roof and wall thermal
insulation, daylighting throughout, north-facing
glazed areas to receive winter sun, sun shading
to control heat gain.
