Goolwa House
The brief called for a low maintenance dwelling (used in the
first instance as a weekend retreat and later to become a permanent dwelling)
that would engage with its great location.
It is in a highly corrosive environment 250 metres from breaking
surf. The southern (rear) boundary of
the site abuts a coastal reserve containing primary, secondary and tertiary
dunes. The house has been sited to
maximise its relationship and connection to this wonderful dune landscape and
the external materials chosen will weather to reflect the exposure of the site.
The climatic conditions are extremely variable featuring
strong winds (bearing sand, salt and rain) from the south west quadrant,
cooling on-shore breezes (SE to SW), hot northerlies and occasional breathless
warm nights. Accordingly the house has
been designed to mitigate the less pleasant conditions while maximising the
benefits of the benign weather events.
Timber decks to the north and south provide outdoor living opportunities
in almost every kind of weather.
Variable shading to the northern deck provides amenity in both winter
and summer while the solar panels provide shade to the southern deck.
Generally, construction materials have been selected for
their low-corrosive qualities, durability, energy efficiency. They include a
slab on ground (to take advantage of thermal mass), well insulated lightweight
walls, simple roof form falling to one SS gutter to one downpipe to water
tanks, natural anodised (25 microns) external door and window frames and
external shading. There is no air
conditioning (heating via slow combustion wood fire).
Having now been through two summers with days above 40
degrees it is clear that there is no need for air conditioning.

This project proves that air conditioning is unnecessary if
houses can be designed to work with their environment employing simple
principles of well controlled cross ventilation, good insulation, external
shading and sun control.

This project demonstrates that air conditioning is
unnecessary if houses can be designed to work with their environment employing
simple principles of well controlled cross ventilation, orientation, good
insulation, external shading and sun control.
Sustainable principles followed in this project included:
·
Slab on ground to take advantage of thermal mass of the
ground;
·
Collection of rainwater from entire roof;
·
Low-embodied energy construction materials including timber
framed construction for walls, timber framed upper level floor and roof
framing;
·
Sunshading and sun control;
·
Solar hot water system (evacuated tube);
·
Timber cladding to external walls - certified plantation
timber;
·
Good insulation (combination of air-cell sarking and batts in
walls and roof);
·
Light coloured roofing;
·
Minimal use of external materials with coatings (roofing
only);
·
Robust materials with non-corrosive qualities;
·
PV cells generating electricity which is fed back into the
Grid.
·
Heating is provided by a slow combustion wood burning fire
and one only small gas heater (LPG).

Sustainable Architecture
Combining successful form making
with an enthusiastic ESD approach doesn’t always make for successful form
making. This is not the case in this
well considered beach side house.
With attention to detail, the
Architect has produced a house that utilises natural materials that are both
elegant in their simplicity, yet represent a strong approach to sustainable
design.
This house incorporates good
orientation, appropriate insulation, good natural light and provides abundant
cross flow ventilation, providing a building that is comfortable, without the
need for air conditioning.
The innovative use of a long PV
array and a bank of hand operable horizontal screens, become strong design
features in the overall composition of the house, beyond their place as
sustainable inclusions.
Ultimately this house proves that
an intelligent and creative approach incorporating sustainable principals and
materials can produce an architecturally strong building, proud of its ESD
inspired roots.
