To build a small cost effective residence with environmental
technologies; where low energy demand minimises the size of
energy systems required. The project emphasised waste re-use
systems to maximise the opportunities for permaculture
development on the property.
The l5ha land parcel is remnant original bushland surrounded
by road easements and farm land. An existing shed, rain water
tank and stone shelter were located on the crest of the land
form in the centre of the land. An existing bench situated
north of and at a lower level than this existing development
intended by a former owner for a house site is re-used as a
levelled area for the permaculture garden activities.
The building site has good northern solar access and is close
to the existing water tank.
The brief called for re-use of the existing stone shelter,
incorparating a new roof and additions housing ablutions
and bedroom spaces.
The building was built-on in fibre cement wall claddings
on insulated timber wall and roof framing and steel roof
deck. The roof pitch suits solar system mounting.
Rain water is roof collected and stored in the existing
tank, gravity and pump reticulated to the house.
Solar hot water service is situated in the ceiling with
panels on the north roof pitch.
A wood stove provides space heating.
Solar photovoltaics on the northern roof provide power
to batteries located on the western verandah and services
an inverter and 240V AC reticulatíon in the building.
Waste disposal is in separate systems, one to compost
toilet, and a separate grey water disposal to reed
bed and the garden on the lower bench in the land.
Comfort is achieved by manipuilation of the openings.
The loft bedroom can be improved by incorporating a
