The home was sold on Wednesday by the executors of her estate, public records show.
Buyer interest was strong despite the widespread challenges in completing renovations due to a shortage of materials and labour.
It drew 155 enquiries during its campaign, Woodards Camberwell selling agent David Gillham said.
The underbidders were a young couple hoping to renovate, while the winner was bidding on behalf of an unknown buyer, he said.
He said a redevelopment was unlikely due to the heritage restrictions and a large easement that runs through the 2000-square-metre-block.
“There is probably nothing you can do with it other than renovate,” he said. “It’s a shell of its former glory.”
Inside, the home has mostly been stripped except for the kitchen, three partitioning walls and one bathroom, he said, calling it a “huge project” that needs $1 million spent on it.
Heritage Victoria issued a repair order in 2020 for urgent works to the house and these were completed in April 2022.
Camberwell’s median house price was $2.5 million over the year to March, Domain figures show, up 22 per cent from the previous year.
Other heritage-listed buildings designed by Boyd include another of his former homes in Walsh Street, South Yarra, and Brett House in Toorak.
One of his designs in North Warrandyte recently found a buyer after being listed with a price guide of $2.25 million to $2.45 million.
