Night Sky, the Blackheath home built for the late astronomer Basil Borun, has been listed with $3.3m to $3.5m hopes.
It first sold in 2023 for $3.222m to Professor Allen-John Collins.
It won the Robin Boyd residential architecture prize in 2021 for Peter Stutchbury Architecture.
Borun, who at one time worked for National Aeronautics and Space Administration (NASA) and was reliant on a wheelchair, looked at the stars through an elliptical skylight in its parabolic vaulted ceiling.
Night Sky has been relisted at Blackheath.
“Completed in 2020, Night Sky has been designed to reach for the stars.,” the listing for the home reads.
“The key architectural feature is the parabolic vaulted ceiling, a self-supporting structure made of recycled bricks, having a 3.5m by 2.5m elliptical, unglazed skylight that retracts to gaze at the stars.
“The house looks to the future, designed to last beyond 120 years, it produces all its own power and collects all its own water. The house also references the past, the spaces feel ancient and modern at the same time.
“The main living has been compared to ecclesiastical spaces, the procession of the blade walls and long interior sight lines echo ancient colonnades.

The skylight retracts.
The truth is out there.
“Fixtures contrast to create contemporary touchpoints that are a joy to use. The meld is simply uplifting.
“The large, voluminous main living space is flanked either side by living wings. One, the master suite with ensuite and dressing and the other, laundry, second bedroom, bathroom and studio/home office.
“The house is located at one of the highest elevations in the Blue Mountains, a little over 1,000m.

“But its passive design, orientation, underfloor heating, solar hot water and large combustion stove creates a physically comfortable and emotionally uplifting everyday experience – what more could we ask for from a home?
“The two wings enjoy a north aspect and the main living opens to lawn to the west and native garden to the east. Set on a 999 sqm block, backing onto Blackheath Golf Course, the house enjoys long views of the golf course.

The key architectural feature is the parabolic vaulted ceiling.
“The long shadows that stretch across the fairway before dusk are beautiful but the promise of connecting with nature’s most spectacular view and its deep mysteries is simply mesmerising – all at a press of a button.
