A new casual living area

Prospect SA 5082
Completed: August 2011
Cost range: $300,000 – $350,000

Houses from past eras have traditionally placed bedrooms along either side of a corridor off a main entrance. This is the way in which this house has been configured, and it means visitors have to traverse private areas of the house before they enter into living spaces. In the re-design the entry has been relocated along the side of the house which then leads visitors directly into the new casual living area with views to the rear garden.
The new living space faces due north allowing for all the design features that enable high levels of sustainability and comfort whilst providing unobstructed views of a rear garden and encouraging copious amounts of light and spaciousness to infiltrate the space.

  • Wide roof overhangs to shade walls and windows
  • Sloping ceilings with high level windows opening outwards from the bottom to exhaust hot air by convection

  • High thermal mass in floors exposed to the northern sun
  • Solar pergola shading northern windows
  • A 22,00 litre rainwater tank to harvest stormwater from new roof area
