A modest 1940’s austerity style home

Lower Mitcham SA 5062
Completed: June 2014
Cost Range: $500,000 - $600,000

This addition to a modest 1940’s austerity style home has transformed it into a 21st century 3 bedroom home with all of the comforts needed for a growing family. Sustainability was a driving motivation for the clients so that they can go forward using minimum energy whilst enjoying the benefits of a free running building. The additions include a new open style living, dining and kitchen, bathroom, study, wine store, walk in robe and en-suite. Remodelling of the existing house has produced a new master bedroom and sauna. Externally a new lap pool, spa, deck and landscaping has also been added together with rainwater tanks. The original house faces east and the rear yard’s long axis was north-south. It was therefore important to set the new additions to the southern side of the block so that the maximum solar exposure could be gained for the new living spaces.

 

SUSTAINABILITY FEATURES:

  • Plan shape to optimise solar access
  • Thermal mass in floors (polished concrete)
  • Sloping ceilings with high level opening windows to vent hot air

  • Rainwater tanks fed by all new roof areas
  • Liquid pool cover to reduce evaporation
  • Hydronic heating
  • Future photovoltaic array
