No. 1 Wingadal Cres, Point Piper, is expected to fetch $60 million at the November 23 auction.

Sarah Cooke moved to London in 1989, she sold her tiny Bondi flat to fund a deposit on a family home in Notting Hill.

“I promised myself that, as soon as circumstances allowed, I’d buy a little bolthole back in Sydney,” she said.

With 1 Wingadal Place, Point Piper, the environmental lawyer and lecturer has outdone herself.

It’s set to go under the hammer on November 23 with auctioneer Damien Cooley.

Raine and Horne Double Bay’s Alex Lyons and Luke Hogan believe it could fetch $60 million.

There’s space for a private slipway on the waterfront.

The windows maximise the benefits of cross-ventilation and disappear into the walls when fully open.

That would smash the previous auction record of $23 million set by Mr Cooley in 2009.

The brand new five-bedroom, six-bathroom waterfront trophy home, built over multiple levels and featuring a lift, has iconic harbour views.

And you can’t get much more exclusive. It’s one of just three houses in a cul-de-sac off Wolseley Rd, Australia’s most expensive street.

Aussie John Symond owns the house next door. He realised he couldn’t let go of his two years ago, even for $100 million.

There are tranquil harbour views from the infinity pool lined in Cait Rosso red marble from Europe, which tones in exactly with the copper clad roof of the poolside studio and shower room.

The garden design was by landscape architect Craig Burton, and executed by a team from Growability at the Windgap Foundation, a charity for people with intellectual disabilities.

His block is bigger, but Ms Cooke’s house is an architectural masterpiece.

In 2006, 17 years after she made that promise to herself, Ms Cooke snapped up the Wingdal Pl site at a foreclosure auction.

“It was like I’d won the lottery … I thought it had incredible potential,” Ms Cooke said, turning to old friends from her Sydney University days, Jonathan Temple and James Stockwell for the original design for an energy efficient house which opens up to provide airy living spaces on all levels.

The woven vaulted copper ceiling is a unique feature.

Ms Cooke personally chose the reclaimed Karri wood.

The project was further developed and construction was supervised by award-winning architects Huw Turner and Penny Collins.

The secret to the completed home is the selection of natural materials.

Ms Cooke personally chose the reclaimed Karri wood. Sandstone came from Wondabyne on the Central Coast and marble from the family’s own quarries in southern Europe.

The one-of-a-kind woven vaulted copper ceiling on the top level was Mr Turner’s idea, who says: “We wanted to bring a combination of classic materials that while contemporary provide a sense of drama, warmth and permanence.”

A turntable in front of the double garage assures easy access.

There’s also an automated Panoramah! window system from Italy. “These windows maximise the benefits of cross-ventilation and ‘disappear’ into the walls when fully open. It’s an understated, simple touch yet dramatically frames some amazing views,” Mr Turner says.

There’s an infinity pool lined in Cait Rosso red marble from Europe which tones in exactly with the copper clad roof of the poolside studio and shower room.

The whole house opens up to the outdoor entertainment areas.

The views don’t get much better.

Other eco features include photo voltaic panels, a grey water recycling system; solar hydronic heating in the bathrooms.

The home has custom LED lighting by designer Tim Barry, manufactured in Australia by Opal Lighting.

It’s designed to be able to be converted into up to three apartments in the future.

The garden design was by landscape architect Craig Burton, and executed by a team from Growability at the Windgap Foundation, a charity for people with intellectual disabilities.

Subject to council approval, there’s space for a private slipway on the waterfront.

Mr Hogan said: “We are expecting a significant degree of interest in this special home both locally and internationally.”
