The estate represents more than a quarter-century of dedicated horticultural stewardship by the late John Egan, a distinguished management consultant and former Trustee of the Royal Botanic Gardens & Domain Trust, and his wife Margot.
What began as a remediation project in the late 1990s evolved into one of the Blue Mountains' most comprehensive private garden collections, featuring over 200 varieties of cool-climate trees and shrubs across European-inspired landscape architecture.
"This is an extraordinarily rare offering," said Nic Krasnostein of Ray White Double Bay.
"Properties of this scale, historical significance, and horticultural maturity simply do not come to market. The Braes represents a lifetime of botanical dedication and the preservation of Paul Sorensen's landscape design legacy."
The Sorensen-designed gardens feature original heritage walls and have been carefully restored and expanded to include:
Dams, streams and ornamental bridges throughout the grounds
Formal entertaining areas including a gazebo
Productive orchard and advanced propagation facilities
Comprehensive irrigation and water management systems
Fully equipped machinery shed with amenities
The estate comprises two separately titled properties that may be purchased together or individually:
The Main Residence (64-68 Grose Street) offers expansive two-storey family living with formal and informal spaces, three primary bedrooms plus a media room, and a versatile 300sqm lower level providing multi-generational flexibility. The chef's kitchen features dual butler's pantries and both gas and induction cooking, while an elevated alfresco balcony captures sweeping garden views.
The Chalet (14 Beattie Street) provides self-contained guest accommodation or independent living space, ideal for extended family, staff quarters, or rental income.
Despite the estate's scale and privacy, it sits within easy walking distance of Leura Village's boutique shops and restaurants, and Leura Railway Station, offering direct access to Sydney's CBD in approximately two hours.
"We're seeing strong interest from Sydney-based high-net-worth individuals, particularly those with a passion for horticulture or heritage conservation," Mr Krasnostein said. "This property appeals to multi-generational families seeking a private Blue Mountains compound, serious gardeners who understand the rarity of such established collections, and those who appreciate the opportunity to become custodians of a culturally significant landscape."
The separate titles provide unusual flexibility, accommodating extended families, guest accommodation needs, or investment structures.
The Braes Heritage Garden Estate is being offered via Expressions of Interest, with price expectations in the range of $8.5-9 million.
