The Hermitage, Denistone, NSW It took five years to conserve this State-listed heritage home in Denistone near Ryde (Sydney). Commencing in 2009, the works were completed in 2013, Heritage 21 worked closely with the owner, the expert heritage builder (Hany Sawires) and heritage landscape architect (Michael Zinn). The house was originally constructed in 1842 and inhabited by the one of the famous explorer; Gregory Blaxland. Heritage 21 presided over the entire refurbishment of the building selecting all the colours and finishes throughout. The clients were very happy with the result as was the Denistone and Ryde communities who saw the grand home fall into disrepair from the 1950s until the refurbishment and restoration works commenced in 2009.
