The quaint heritage garden village of Mount Wilson was settled by the well-heeled society in Sydney as their summer retreat in the 1870's. ​ Dennarque Estate is situated on the highest point in the Village. The original sandstone house was built in 1879 by former Aide-de-Camp to the Governor, Commissioner for Crown Lands and Clerk of the Executive Council, Edward Merewether, who lived there with his wife Augusta and 10 children. ​ The original gardens were designed by Charles Moore, Director of the Royal Botanic Gardens Sydney. ​ Rarely open to the public, the extensive manicured cool climate gardens are ideal for the perfect retreat, or a boutique, bespoke wedding for up to 50 guests. There are 3 cottages on site, Camellia Lodge and Wisteria Lodge which have a King size bed, and Koonawarra which has 3 bedrooms - one with King size bed and 2 with Queen size beds. The property can host up to 12 persons in 3 cottages. ​ Today, Dennarque Estate is available to those who wish to experience nature at its best as an in-house guest.

The current hosts have been custodians of Dennarque Estate for over 20 years, and have done extensive works in the gardens, and the properties.
