PRC Building uses conventional building techniques including steel frame construction, and progressive construction methods, including straw bale house and rammed earth.

Straw bale houses have a significantly lower energy input than traditional brick housing. In addition, straw insulates better, saving energy in heating and cooling costs. Straw also offers an aesthetic advantage to conventional methods of build.

PRC Building and Peter Costa is the only preferred WA contractor of Ausbale (www.ausbale.org), the leading association in Australia for straw bale housing and building.
