"Hawthorn Hill" is an easy 2 hour drive from the Sydney CBD and offers 5 acres of complete perfection, a verdant family haven of lush rolling lawns and magical gardens. The private sweeping gravel driveway culminates at the front portico of an incredible, bespoke 5-bedroom residence that embraces the phenomenal surrounds whilst capturing endless natural light.
Held by the same family for over 35 years, this architecturally designed home clearly conveys the thought, love and care that went in to its creation, from the hand painted foyer to the inspired layout offering incredible spaces to entertain and enjoy. You can easily imagine a lively lunch in the dining room before afternoon tea in the conservatory or musing in the library where time just seems to stop...so you can relax into a cocoon of absolute bliss.
When it comes to accommodation Hawthorn Hill aims to please. There are of course the 5 bedrooms in the main house (two with en-suite) as well as an office and a study, however if you are looking for total seclusion you can't beat the self contained love cabin tucked away behind the formal garden.
There is yet another spacious two bedroom self-contained cottage. Affectionately referred to as Cooks House, a fantastic addition given that it currently generates a lucrative passive income as it sleeps 6 guests and boasts many 5 star reviews as a peaceful weekend escape.
You, your family and guests will no doubt enjoy the extensive gardens, a friendly game of tennis, boules or even life size chess before an afternoon boat trip on the private lake. However if you choose to venture beyond the boundary of Hawthorn Hill the picturesque hamlet of Mount Wilson will leave you speechless. Astounding beauty, unique architecture and fascinating history are beyond compare.
Hawthorn Hill is the ideal family complex that will allow your lifestyle dreams to become a reality.
