An under-construction Toorak apartment project is close to selling out after a mother-and-daughter duo snapped up two adjacent apartments off-the-plan for a combined $17 million.

The dual deal follows developer Orchard Piper selling two penthouses off-the-plan in May last year in the same project (known as Toorak Village) for a combined $23 million to downsizing locals. The project’s 400-square-metre top-floor penthouse sold for $12.5 million in 2023 to a local retiree.
