'Wynstay Estate' Magical Mountain Retreat - An Australian Treasure.

Commanding the crest of Mount Wilson, Wynstay Estate is one of New South Wales' most celebrated and historically significant private holdings, a landmark property that has remained in the Wynne family since its establishment in 1875.
Created by Sydney merchant Richard Wynne, founder of the prestigious Wynne Art Prize, this extraordinary estate stands as a living record of heritage, architecture, and horticultural beauty. Across its park-like grounds, Wynstay offers an irreplaceable blend of stately residences, rare period outbuildings, and magnificent formal gardens that together form one of Australia's most complete 19th and early 20th-century Hill Station estates.
At its heart stands the grand sandstone homestead (1921-1923), designed by renowned architects Joseland & Gilling in the Inter-War Georgian Revival style. Built from locally quarried sandstone by Scottish stonemasons, the residence embodies refined craftsmanship with hand-cut stone, paired Doric columns, and sweeping views over the Blue Mountains and Wollemi National Park.
Complementing the main home are several heritage dwellings and outbuildings that together define the estate's unique character. The original 1875 two-bedroom Carpenter Gothic cottage, built from locally milled timber, reflects the earliest chapter of Wynstay's story with its floorboards fashioned from rejected Blue Mountains railway sleepers personally hand-cut by Wynne himself. Nearby stands Old Wynstay (c.1880), a four-bedroom Victorian vernacular home with a wraparound verandah glazed with etched and stained glass of Italian origin, offering rare secondary accommodation or guest residence potential.
At the entrance, The Lodge (c.1891), the original gatekeeper's lodge, is a striking architectural gem built on a hexagonal plan with a central fireplace and flues radiating to four rooms, complemented by two attic rooms above. Together with the basalt and sandstone Coach House and Stables (c.1890), complete with crenellated parapets and a domed brick water tank, these structures showcase Wynstay's remarkable attention to design, proportion, and enduring functionality.
Among Wynstay's most exceptional features is the private Turkish Bath House (c.1892), a rare and elaborate building of polychrome brickwork, cast-iron ornamentation, and Italianate detailing. One of only two private Turkish Baths remaining in Australia, it features patterned ceramic floors, painted vaulted ceilings, and arched double-glazed windows is a testament to the family's cultural sophistication and the estate's national significance.
The gardens that envelop these buildings are equally remarkable. Mature conifers, oaks, redwoods, magnolias, cherries, and maples frame the estate's avenues and terraces, interspersed with romantic garden rooms including the Sunken Garden and Italian Garden (Mimi's Garden). Fountains, statuary, Goodlet & Smith urns, and stone pathways create a sense of harmony and grandeur reminiscent of the finest English estates.
As the largest private landholding in Mount Wilson, Wynstay represents an unparalleled opportunity to secure a property that is as beautiful as it is historically important, a living estate of rare architectural depth, horticultural splendour, and unbroken family provenance.
