Limestone House passive house in Toorak for sale

The Limestone House, a sustainable passive house located in Toorak, Melbourne, has been put up for sale for the first time. The property is quoted between $11.5 million and $12.65 million.

Designed by architect John Wardle, the four-bedroom, four-bathroom residence is the first in Australia to be constructed under both Passivhaus principles and the Living Building Challenge. These standards require the home to operate as a regenerative environment, meaning it must manage its own water and generate more energy than it consumes.

The home was built by David Sutton, chairman of the clean energy technology company RayGen, who sought to combine high-end architecture with strict energy-efficiency standards.
