The luxury home features a 25-meter sandstone tunnel beneath the property, a swimming pool, automated music and lighting, a gym, and more.
After 20 years, owners Rob and Wendy Procter are selling the gadget-filled property for “another adventure” and for “someone else to enjoy.”
The Procters also claimed that the 63 steps to the top of the house were one of the reasons they were selling the property.
“We’ve climbed those 63 steps for 40 years shopping in the rain, that’s the answer,” Mr Procter said.
The Procters said even James Bond would enjoy the house.
“I think he would find it inspiring,” Ms Procter said.
Most home gadgets can be controlled by your phone.
“We can turn on the lights, open the doors, turn on the music, anything in the house,” Mr. Procter said.
The property has a tunnel which was used to install the elevator at the back of the house.
To build the tunnel, the Procters employed five opal miners from Lightning Ridge.
It took the miners three months to dig the cavity, but the fact that the stone was completely dry added to the tunnel’s appeal.
“We were also lucky that it was dry, the stone was nice and dry, they were so skilled and the way they built it is so smooth,” Mr Procter said.
One of the biggest problems during construction was the removal of the 800 tons of rock that were excavated during the excavation of the tunnel.
It was transported by cranes to North Bridge to expand the golf course.
