This Blue Mountains home was designed to integrate seamlessly with the outdoors and to hold a comfortable temperature all year round without the need for air conditioning.Tim and Madelyn, with their daughter Frankie, were ready to move away from city living, so bought a property in the Blue Mountains in 2017. The 1800 m2 block slopes east- west, with high surrounding hedges, creating a secluded private oasis.The original house was demolished, with minimal disturbance to the land, as it was beyond economical repair. All masonry products, timber, steel and plaster was separated and sent to separate recycling facilities. A new 300 m2 energy-efficient home was built. The design follows the slope of the land, split over three levels.
